warning this does not work every time i got 2 identical ram kits just like this same color even lol did not work for me it will not keep the xmp profile i have no clue why it runs fine without it.
I believe 90% of techtubers are really just basic users with an audience usually obtained by having a goofy/silly personality and a [confusing] passion for tech. I can't yell you the last time i really learned anything in say, a build video. I like this video for calling out those other channels.
Almost 2 years and this video still helps people like me. I have exactly same problem you had, lucky I also have the same kit available I bought a year ago. Thank you!
2 Years ago I studied a course for Computer Technician. I finished it but I can't say i'm experienced in terms of computer. But, i'm pretty sure I learned that when adding more rams, it is advisable we get the same brand/model. Now I'm here double confirming if my memory is serving me right. The intro answered my question LOL.
It's crazy how i had to watch 6-7 videos of 10+ mins each just to decide buying the same kit of x2 8gb i already had so i could upgrade from 16 to 32 gb ram, and then i decide to double check and watch 1 more video and find this, the exact same kit i bought, in a shorter video, better explained and with a relaxing voice. Thank you man
Absolutely helpful. I got two pkgs of the same ram when I bought it, just because it was on sale. It was my first computer build in years. It used to be ok but wasn't aware of these other issues I started to learn about. So I thought I did something wrong. Your the first one to point this part out. Because like you I haven't seen anything wrong. And it loaded the XMP right out of the gate. After I turned it on. So thanks for the vid.
Amazing how technology has advanced and now does it all for you without having to apply too much if any effort at all. Over a decade ago I done something that wasn't recommended and mixed different speeds of ddr2 ram from different manufacturers to populate all the dim slots on my gigabyte mobo, my memory downclocked to the ram sticks with the slowest speed, my PC ran fine and surprisingly never crashed or blue screened when I thought it would.
That is correct, but you should also mention, that sometimes finding excatly same kit of RAM is very difficult, also in some country's if it is sold out "impossible". That's why in my opinion spending right away ( for example; double money ), and not ever worry if it will be enough, and spending time trying to find same kit, it's worth it getting more RAM than person currently needs.
Very informative and straight to the point. I recently did this 16 to 32 ram update and used the same kit as you. I like the low profile of the Vengeance ram.
There is one important detail you left out. The ram you bought also comes in a 4x8gb kit, model number CMK32GX4M4B3200C16, which happens to be on your motherboard's QVL. If you're upgrading from 16gb to 32gb like this, make absolutely certain that the 4x8gb version of your kit is supported by your motherboard - sometimes its not.
Can this be pinned to the top? I myself have purchased a second kit of 2x16Gb memory for it to fail like crazy. I just looked at the motherboard specs and sure enough, only 2 sticks are supported, making the other two just paperweights. I need to purchase very specific ram to get all four slots filled. Its pretty annoying.
Was looking for this exact situation. As this is what I'm running into. The only difference I saw on my sticks is the version on both sets. One is 3.32 and the other is 4.33 so I'm still not 100% sure if it's OK but looking at this, it should be fine.
i have the same kit and im too making it 32gb,my mobo doesnt support it at 2x8 and 4x8 but im currently running it for the past 4years 2x8 and its working ??
wow looking for about half an hour for a video that just explains it in a real scenario, always a small channel with the most helpful content 👍 saved me a lot of time
Great video! You helped a great deal as I'm the in the boat you were in. Thank you for being straight to the point with great info! You answered questions I had when upgrading RAM; I even have the same exact brand and model you have, though mine is 3000 MHz and red. But good to know that I can now comfortably purchase another 16 GB to add more RAM!
DDR4 is very forgiving. The main thing to remember is try to stick with the same kit if you can and if you cant then at least stick with the same speeds and timings. Even now with prices for RAM super low a 4 DIMM kit is still expensive and even just getting two of the same 2 DIMM kits at the same time often will be cheaper, and in some cases could even be half the cost. If you are adding ram in the future and can not find the exact same kit however you can mix kits but will have to be prepared for running everything at lower speeds or timings if the added kit does not match up to what it says it can do. So if your only option is to just buy another kit because your kit is not available any more make sure all of your ram is from well established venders as they will be more likely to preform to what is printed on the box. Though even then that may not be the case depending on your motherboard, CPU, and just getting unlucky. I had a 16gb kit of ADATA that was rated for 3000 but it only ran at 2666; still better then the DDR4 default of 2132 but not what is printed on the label either. You may also have to manually adjust everything if the kits do not match as XMP likely wont work correctly with mismatched kits Also for those who are unaware DDR4 is only rated for 2132 which is the default. Anything higher then that is factory overclocked from the base standard. Additionally if you are looking in your system and you see a much lower number like 1600MHz that is correct as the printed number (3200 in this case) is double what the actual speed is as the DD stands for double density. Your BIOS should display the full number if you are using XMP though.
I did a bit of research on the topic. From my understanding, crucial memory would be the absolute safest bet for higher capacity ram kit upgrades. (Reason) Crucial makes their own ram chips (micron parent company to crucial) As we all know, Corsair doesn't make ram chips. So for Corsair to guarantee that memory works for kits only indicates they use different chip manufacturers in each kit based on market price and availability. So the sub-timings can vary from chip manufacturers. That's when the average person can run into possible instability issues. The solution: if memory is unstable for 3200MT/s for instance on two identically spec kits. Run them both at 3000MT/s as the speed and Sub timings should be matched by the motherboard. Validate in CPUZ that all Sub timings are the same and run a mem test through windows memory diagnostic at the minimum. Also mixing capacity can cause potential issues, such as 32gb kit and 64gb kit to get a total of 96gb. One kit may be single rank, while the other may be dual rank. This can cause an issue. Again two larger capacities can also have denser chips between modules, despite having the same brand timings ect. I think a more comprehensive video could be good for this channel. I do think buying identical kits by the manufacturer will yield good results 90% of the time. I have mixed two of the same brand kits before and did have an issue once, and did have to step down the speed to a pre-defined timing on the motherboard. However i fo not overclock ram and play with timings as i dont have the time, no pun intended, to spend getting a fraction of an FPS when not being GPU bound.
I did that with Trident Z 16gb and got the same speeds and Trident Z ram but with 32gb and used them together. PC saw all 48gb, XMP profile worked flawless and ran without issues for two years until I sold the PC.
As long as the timings etc are identical you can use a different capacity for each slot. So you could do 4gb 8gb 16gb and 32gb populating the four slots and have no performance issues.
I'm doing this exact thing with my current build. I got a deal on two packs of 2 sticks for 4 sticks of total ram. I expect the XMP to work on the first boot, if not I will lower the ghz a little worst case scenario, with the XMP on. I've done this on past builds when getting a deal on PC parts. Just doing the best I can with my resources.
I upgraded to 32 Gb last year but I couldn't get the exact timings. But it is the same MFG and brand but what I had was 3200 and the other 16 Gb kit is 3400. Now I hated to do it but in this case I knew that it would all work but I would not see any of that 3400 performance because it will bring them all to the same sppeds and timings. But hey. Works greak. And it was Ripjaw by the way.
Different timings will work because the mobo will default to the lowest set. Ram can always be run slower than its rated speed and have no issues. Mixing different brands and timings tends to be an issue on oem workstation office type pc that are only compatible with certain timings and capacity. Dell and other major office pc makers do it to make the cheapest possible product. But if you buy any over the counter mobo from the typical vendors then they nearly all support mixing ram types and speeds.
I’m looking at doing the exact same thing. I have the exact same Corsair RAM kit and I’m also thinking of going with the second set as white like you as my case is white. My mother board is a bit older (MSI Z390), and I’m hoping adding more ram will help speed up my PC. Thanks for posting this video!
You definitely can mix and match memory from different manufacturers. No harm to your system. I’ve done it on several occasions, and have never experienced any issues
been doing it ( not on gaming ) but on p.cs and laptops since windows 2000. I always new it wasnt the best. but not once have i had an issue. Except dell. Dell did NOT like anything other than dell.
I also bought the same kit 2 years later and ran into a ton of problems (BSOD frequently). Haven't nailed down if it's a problem with the newest kit or just a problem with the different kits working together. So it may just be hit or miss for everybody.
Hi there im experiencing the same thing. I have the exact same RAM kit too but i get BSOD. Tried memtest and it seems individually the ram doesnt have any problems but together, they keep getting errors. Have you found a solution for this?
@@nissa7825 Yep I just built my son a PC for Christmas and used the newest set of ram sticks. He's had no issues using them. Together in my system it was giving me BSOD. Really weird how that works. I never tested changing XMP profile but it could be an issue with that setting. I'm not sure though.
@@imhooks i see, thanks! Ive been trying and trying nonstop to get both of my RAM working smoothly and what worked for me was to set the DRAM Frequency in bios to 2400 MHz instead of 2666 MHz. Both of my RAM sticks were HyperX DDR4 2666 MHz 8gb (literally same everything except for the manufacture date i guess). So far i havent had any problems and it passed memtest too.
@@nissa7825 Yea I figured it was probably something to do with frequency and/or XMP profiles. Did you try setting it to 2400 restarting BIOS and set it back to 2666 at same time? Not that losing that 266mhz is going to make much of a noticeable difference. Edit: This is something that I didn't think to try. I should have reset the DRAM settings in my BIOS prior to installing the second set. Then applying XMP profile on all 4. Instead I just installed the new ones and didn't make any changes.
@@imhooks nah i didnt try it anymore, I've been trying endlessly for days to get it to work properly that when I was able to make it work, I didnt wanna touch it anymore for fear of just messing everything up again lol (i'm not a pro in tech stuff and my field of expertise is far from it thats why im actually scared to touch stuff when its working properly) But yea, I also found out only 1 of my RAMs had XMP which was kinda weird. In the end I just set XMP to auto and the only thing I changed was the DRAM Frequency
THANK YOU!!!!!!!! I'm in a pretty similar situation with the same RAM model and an MSI motherboard with 2 dual channel slots- the difference being that in my region there's not a single place online or physical where I could find an 8*2 ram kit, only single sticks are available now so I have to buy 2 identical ones.
This has always how I have done my upgrades. I buy how much I need when I build the pc, and double it later down the line as requirements grow. DDR3 was 8gb to 16gb, and DDR4 was 16gb to 32gb. The one caveat is that you should still try to keep the sticks as a pair, as mixing between the two sets can, but not always, cause issues. For example, kit #1 you might put in slots 1 and 3 to keep as a pair, and kit#2 you put in slots 2 and 4. A lot of kits will have some sort of version numbers on them so you can tell which set are a kit even if you get them mixed up. Worst comes to worst you can always swap between DIMM slots until it posts correctly.
Awesome! Thanks! I had 2x16GB then I bought an X299X and bought a second set of 2x16GB and a 4x16GB kit. All the memories were the same G-Skill memory but I kept getting errors when running XMP. Only later I found out the QVL says that I can only populate 4 of the 8 sockets with that memory ... and that got me somewhat mad at myself. Memtest86 quickly showed errors when running the 8 sticks at 3200MT/s but the system is pretty stable at 2133MT/s. 2133 is somewhat slower, though ... Oh, btw, 4 sticks used Micron ICs and the other 4 used Samsung ICs ... that got me mad at G-SKill!!! I'll check what happens if I use only 4 slots. My goal was to have a few VirtualBox machines running but it did not work that well, though. Thanks for the video!
The Takeaway is that you can Most certenly do this on DDR4 but it might very well be Diffrent story on DDR5. as you are very likely to run into issues with 2 identical kits if you enable XMP on DDR5. you might get lucky and it works but chances are slim as of right now at least. but you can just disable XMP and try your luck with manual setting the ram settings!
I feel more confident now adding my old corsair vengeance 16gb 3600mhz to my current corsair vengeance 32gb 3600mhz. Gonna go ahead & install it tomorrow. I will update this if all goes well.
@@notanothertechreviewer yeah, 2 separate kits. I haven't got around to installing them yet, but from my understanding, they're identical other than memory size. The motherboards manual suggests it should work fine. I may have to adjust my bios to get them working efficiently
@@connorwest465 As I mentioned in the video, it's best to go with kits that are 100% identical, and that includes memory size. However if all other specs are the same, you might still be OK. Hope it works out for you :)
I think it goes without saying that the exact same model of RAM will work together, yeah. When most people ask if they can mix RAM, usually it's whatever RAM they have and the cheapest RAM available, thus they'll probably use a different brand. Of course it will cause problem. Good video, eitherway.
Mine are same as you have but my 1st kit was 2x8 kit my 2cnd kit was 2x16 both were 3200mhz total of 48 gb Works fine. A & C channel has 2x16 kit B&D has the 2x8 kit. Bought 4 years apart .👍
Well I upgraded to the same ram same mhz same brand same cl16 3200 ddr4 just did 32gb instead and luckily that worked automatically which makes sense it's the same ram just more of it lol. You will always have more issues adding 2 new on top aka 4 sticks instead of just using 2 ram sticks exact same but 32gb instead with 2 sticks. The reason it worked for you is exactly why it did for me. It does auto and boom perfect.
GPU-Z is great. Have found many boards, even if you pick the XMP profile when leaving the timings to auto, on start-up the timings when checked in CPU-Z may be looser than the XMP profile. Recently added 2 additional sticks of Hyper Fury and discovered even though the sticks had identical timings at 3602 that was highest clock for one pair, whereas the 2nd pair had higher clock on 2nd XMP setting of 3730. Running the 2 pairs at 3600MHz without issue. As long as you run identical sticks in pairs and run at what speed and timings the weakest of the RAM can handle don't see much of an issue mixing and matching.
Have you stress-tested the kits? For example, even with just two channels populated from the same kit, I got memory errors on disabling and enabling the memory integrity option in Windows Security. I had to retrain the RAM modules by disabling Memory Context. This might sound irrelevant but one never knows where the problem hits.
bought a laptop recently and was looking at upgrading the ram - the 64GB kit is around £200 in the UK, whereas if I buy two single 32GB sims it works out to around £140!!! Insane and it'll probably be the exact same RAM!
I've done this exact same thing and ran into nothing but problems. so your mileage may vary. I bought the exact same kit of ram for my system and the XMP will not even post. I am trying to figure out now how to get it to post and become stable.
I just did this to Msi Meg Ace x570e with Gskill Trident Neo 3600 8gb. I had 2 for 16gb now added 2 more for 32gb. Both identical kits and same thing happened, got the screen telling me to go into bios. Then everything was the same so saved and booted into Windows and worked perfectly.
@@davidteiman Sorry I am still seeing 36gb I learnt somewhere in maths that 2x16=32 and 4x8 also equals 32 Sorry if I am wrong. I think there is some technical glitch in my eyes or brain.
Same thing with me! I had some money to burn so I upgraded from 16GB to 128GB... but all wasn't fun for me. Reaching limits like that are a little dangerous. I had frequent and random crashes on Windows, with completely random error codes. Some OS corruption occurred but thankfully no data loss and a quick sfc command fixed my machine up. The solution was to look at my CPU's specification, and limit the clock speed of the RAM to the maximum value on the specification. I.e. 4x32GB sticks @3200 MHz with an Intel i9-10900k **must** be underclocked to 2933 MHz.
Not always a fail-safe approach... you just got lucky: I bought the "exact same kit" too, 100% identical product name and model number (Corsair CMK16GX4M2B3200C16 - even in the same colour ;) )... then I found out it depends on how reliable the Vendor is.... after Corsair got lots of positive reviews on their Vengeance LPX 3200CL16 kits, they changed the underlying chips: there was a tiny label under the DDR4 label that changed: I think they were v4.xx and v5.xx.... up to v4 those had Samsung B-Die.... and the later models had SK Hynix. If I borrowed another Samsung B-Die kit, I could still run the rated XMP speeds, but if I tried the 4 sticks of Corsair CMK16GX4M2B3200C1 purchased a few months apart, it was very unstable to the point it couldn't even boot into Windows. I could run either of them at the rated speeds.... I just couldn't mix the Samsung and SK Hynix at the rated speeds, despite them being branded by Corsair as "the exact same kit".
I have a 2 stick 32gb ddr5 5600mhz vengence kit installed....went on amazon and REORDERED the same kit...and my pc wont boot. Keyboard doesnt turn on, nothing. The only difference I can see is that the "old" kit has ver 5 and the "new" kit says ver 4
I did the same but I used 32 gig kits. I went from 32 to 64 with the exact same kit of DDR4 G.Skill 3600. Everything worked but the XMP would not take. The 3600 memory insisted on running at 2100. I didn't have good luck and you did. Oh well, it worked in another build I was doing so no loss really. I am at 32 gigs and staying there.
What is said in this video is mostly true, however I have a ryzen 9 5900x cpu and I'm running 2 separate identical kits of ram. The 2 identical kits i'm running on that cpu are the following speed, capacity, and timings. Each kit is a separate identical kit of 32GB 2x16GB 4000Mhz CL18. I have 2 identical kits installed and running right now. That makes a makeshift ram kit with 4 sticks of ram. So it then becomes 64GB 4x16GB 4000Mhz CL18. I can run just fine with one kit of that ram on my cpu. Then i when added the second kit of ram, my cpu then became extremely hard to get running smoothly. For not very many people 4000mhz with 2 sticks of ram with 32GB can run stably. Be it 2 kits of ram at that speed, amount, and timings. For smaller amount and speeds this method of mixing 2 identical ram kit would be fine like shown in the video. Similar things apply to DDR5 too, DDR5 ram is lot more picky about combining 2 separate identical ram kits. Therefore this video is mostly true. Just remember not to follow all advice you see on the internet. Sometimes that advice would be mostly true as in the case in this youtube video.
Thank you! I could not find a 128g kit of g-skill ddr5 6400 so I bought 2 64gig kits and assumed it should be fine. I have been looking for this answer for ever. You hear and see alot of mismatched ram etc but little to nothing of same kit ram. My 2 ram kits serial numbers are even in chronological order. Last 3 digits are, (197, 198 kit 1), (199 ,200 kit 2), so I got them all off the same line in chronological order which is awesome. So by the way you installed yours the first kit was in A2 and B2 for dual channel mode. And the second kit went into A1 and B1 instead of any random order even if they are all the same.
Hi, It's great to hear about stability of having 4 sticks of ram, but what about the performance ? have you tried any benchmark and whether there's a little performance drop ?
Thank you for this, I did the exact same thing with the same Corsair sticks (only 2133 instead of 3200), but sadly your conclusion didn’t apply to me. My Motherboard recognised all sticks just fine and ran intensive games perfectly without any issues, but Chrome would randomly crash my PC and in general my PC would have random power shutdowns until my PSU would kick in and activate the safety measure. Eventually I even had a BSoD and couldn’t solve it without removing the 2 new sticks again. I ran the old 2x8 sticks for 4 years and never had any issues, so it was no coincidence. I thought the new 2x8 sticks may have been defect, but I decided to run my PC with just the new 2x8 sticks instead as a test, and more than a year later I have never had these issues again. Till this day I haven’t tried running the 4x8 config again because I’m scared to permanently brick my PC, and I still haven’t found any reason as to why 4x8 with two identical dual kits was not functioning flawlessly for me. Maybe I should try it again? Any ideas as to why I may have had these issues?
I can't see any reason even before watching this video why adding in additional identical ram sticks will be an issue? What difference does it make if you install four sticks right away or add in two more later? None. It's like the industry standard for upgrades and why most mid to high end mobo have four slots to begin with so you can add more ram later if needed. There you go saved 6 minutes of your time!
What bothers me a bit is that rams that come in kits (of 2 or 4) have different part codes than single sticks of same product, I am thinking there is a slight chance that a kit of 4 might be tunned (or hand picked) in detail to have the exact same speed tolerance / variations, where 4 individual sticks of exact same product might have higher variations of frequencies / top speeds. They run at extreme speeds so I am thinking they are extra sensitive about running at exact same step.
Not so lucky here. Same Ryzen 5 3600 but using Corsair Vengeance LPX 3600MHz. Brought another exact kit to fill up the other 2 slots (A1, B1) and use it fine for like a month before I get random BSOD and random reboots. My motherboard QVL shows only support for 2x8GB for this Vengeance LPX, not 4x8GB. Wasted 16GB.
There might be some timings set to tight automaticly by your motherboard. For my experience but with DDR5 it were the tertiary timings with start which have the "dr" and "dd" (different rank / different dimm). My system wouldn't even boot with 4 dimms installed because it was automaticly set to tight. installed only 2 dimms and loosened them and after that i installed the other 2 dimms. After that i tightened them to the max.This maybe would work for you too.
i Went full yolo and combined a 32gb Kingston DDR5 6400cl32 with a Gskill DDR5 6600cl36 which i got gifted. Loosened all timings and started with 5400 which surprisingly worked. Then startet bumping all up and both kits are working together with 6000 cl30 and pretty tight subtimings at 1.45v. Both are A-Die Sk Hynix dimms and they can go really low on some timings. 6000 is the thery max my ROG z690f can handle with 4 dimms installed and that is pretty good to be honest and i might be very lucky that this does even work at all with 2 completly different dimms. I have to keep in mind that just resetting Cmos and installing booth kits didn't work. I had to make a very loose memory profile first and then install the second dimm because it automaticly set some timings to tight for it to train properly. Cheers!
I (literally 5mins ago, ironically) just put in 32GB of identical ram to my original 16GB, to make sure they worked. And the mobo didn't even revert from the docp profile either.
this is true for am4 motherboards with good memory controllers like that tomahawk but ive witnessed instances with ddr5 on am5 that will either not boot into the os, get a ram or cpu error light, or only run on base frequency (tested on 4x16gb of same brand, model and chip manufacturer).
My prebuilt came with 32gb ddr5. Just added another 32gb ddr5 two days ago and thankfully so far working fine. Had no messages upon boot up. 64gb total
Some quite switched-on comments below. One thing, I believe that if you mix different speeds & latencies, all the modules will default to the lowest spec, ie. 2x 2133 + 2x 3600 = 4x 2133, at least with DDR4. It might not even boot if you do that with DDR5, though - not used it, so far. But I've often mixed different capacity modules, at least on DDR4 laptops, either 4GB + 8GB or 8GB + 16GB, and that's never been a problem, you just get 12GB / 24GB, happy days!
I Purchased two identical 16GB kits of the same RAM as you running at 3200 CL-16-18-18 but now my system performs slightly worse then my 16GB 2133 CL 14 kit 😞
I think I may be running the same memory as you. It's actually really good chance your running Samsung b-die; They are usually good at overclocking 3200 cl16 cranked up to 3800 cl14. Can't remember been a few years.
I took the same path as you, with the same Corsair kits. Also with no issues, once I enabled XMP. My only hesitation is whether, with all four slots populated, I should have put the two kits into the same channels, instead of dual channeling each kit. So if you did that you'd have your two white and two black DIMMS in adjacent instead of alternate slots. Would that provide any benefit over your (and my) current setup?
you can actually mix RAM from other manufacturers, you just need the same spd and timings. I had a 2x8gb from Avixer and just added 2x16gb from lexar, all are CL16 and 3200mhz all works great without issues.
I bought the same kit as was already fitted even making sure the part numbers matched but the first two were Samsung chips and the second two were Hynix.
I had to slow my 2x16gb 3600 cl 14-16-16-16-32 down to 3200 cl 16-18-18-18-36 with 2x(2x16gb) without crashing. maybe 1% performance drop in games but way better overall for my productivity work. just take the (barely) hit in performance if you need the extra ram. you will barely notice.
Kit have vers8on numbers, if same version, yes it ok. If version difference, it could be because of different ram manufacturer chips... You can also put in different ram chip brands, but depending on board option. You may ha e to setup to your rams worst settings... Like if you got 16 24 24 64, and 2nd kit , 18 26, 22, 74 So you put in 18 26,24,74 timings Run mem86 plus pro , use 1 cpu only for testing. (P.s if you don't run ram test (say 4 loops), Windows will still work, but it can cause stability issues, or corruption when you save data.
Ram is a confusing thing. Good video. 👍👏 I just put 4 dimms (2 kits, same manufacturer, same oem. Different age) into my Ryzen 2700x (linux server) and xmp 3200 didnt work, memtest found countless errors. So i switched manually to 3000 MHz, that seems to work. Happens with old Ryzens sometimes. The same dimms were running perfectly in an old I7 7700k build at xmp 3200. What i cant figure, the kit i switched back into the I7 didnt work with xmp 3200 also, even though it was running perfectly a year ago in this machine and in any other machine i tried. The heck😄
I can see in your video, that you where originally running your ram in dual channel. When you installed the extra Ram modules, you now have a "new" stick and an old stick connected in each channel. Do you know of it would be better/more stable to group the "new" sticks on one channel and the old sticks on the other channel?
was hoping to see you mix different ram sizes from the same kit and see if that mattered, i have that exact ram kit but wanna get a 32 gig of two 16 gigs. would that work?
I read that sometimes you can have issues even ordering the same model/timings of RAM but a period of time apart from one another. I don't know how often this happens, but a number of other posters in the thread seemed to readily agree that even mixing the same brand/model/amount/timings can have issues if they aren't all from the same purchased box.
I am facing the same problem now.😁 I bought two single ram sticks at different times with the same specs except manufactured year and serial number ( not model number).. With my new Ram nothing works..be it individually or together with the old Ram.. Old ram alone in any ram slot works perfectly but not the new ram stick
The main actual takeaway is that mixing will work if you default to the looser speed and timings. Its more beneficial to have identical amounts on each dtick.
I do the same thing today. corsair vengeance 3200. 32gb to 64gb. past the kit i have before in slot 1 and 2, and the new one in slot 3 and 4. 64gb total. same ram brand reference etc. But now in slot 1 and 2 they are in sngle mode, but in 3 and 4 dual channel. How i can get all in dual chanel? tks
If you buy the same one there is still no guarantee that they are the exact same memory chips under the headspreader, what makes the matter worse is that the company selling you these "never validated these for 4x8GB" even tough they might sell a similar kit? Well if the "similar kit" has higher CAS you could manually adjust them to the 4x8GB kit XMP settings and if they are indeed same memory chips it should work.
I was under the impression that you have to keep each pair of ram kits to its own channel memory. But what you have shown here is the ram kits split into two different channels for both. Cause slots 2, 4 are two different channels and 1,3 are two different channels and you have the two different kits paired with each other in each memory channel. I have had ingame crashing issues and i noticed the two middle slots of ram 2,3 are much higher temps than the outside slots 1,4 so i will try your way and see if the heat in 2,3 slots is still higher maybe the overheating is causing the crash cause it happens after like 2+ hrs of gaming.
I have purchased the exact same Kingston fury beast cl17 3600 ram and it doesn't work stable with 4 sticks at 3600mhz only at 3000mhz xmp. This is not an absolute . Maybe with Corsair. Either set works individually at 3600 in a1 and B1. I'm going to try a matching set in a1/2 and same again b1/2 fingers crossed I can get full speed.
Is it okay to add dual channel 2x8gb (3600 CL18) to my existing 2x8gb (3733 Cl17)? it is the same brand and even product number just different speed and timing. I just use around 3200 ram speed in xmp.
i had 2x 4GB Adata DDR4 2600, 288 pin sticks, to add 2 more the exact same would have cost me 200$. Turns out G.Skill Ripjaw makes the exact same ram for 50$ so i bought that, been mix matched for 5 years with no issue. Literally the same ram made in the same factory with different heatsinks and different price. Both casings metalic red btw.
I have the same brand, the same speeds and the same timings but they have different sizes. I took a friend's advice on mixing ram sizes, just as long as the speeds, timing are the same... The Ram arrived today, and I am scared to install it with the old stuff still in there. I most likely will remove the 16GB kit and install the 32GB kit. And then buy another 32GB kit in a couple of weeks.
What about DDR4 16 GB (2 x 8 GB) 3200 MHz CL 16 Corsair LPX and DDR4 64 GB (2 x 32 GB) 3200 MHz CL 16 Corsair LPX together for a total of 80 GB? Do you think it could work?
so can I use my Corsair vengeance pros with my new Corsair vengeance pros? they the same speed n everything else the only difference is my old ram sticks are taller then my new ones.. will that be a issue even tho they the exact same?
Once again, it's always a random small channel that is more useful than the bigger and more mainstream channels.
Thank you.
Glad to be able to help!

I believe it has to do with matching batches. If you get identical sticks from different batch numbers it can sometimes lead to problems

I believe 90% of techtubers are really just basic users with an audience usually obtained by having a goofy/silly personality and a [confusing] passion for tech. I can't yell you the last time i really learned anything in say, a build video.
I like this video for calling out those other channels.
Almost 2 years and this video still helps people like me. I have exactly same problem you had, lucky I also have the same kit available I bought a year ago. Thank you!
2 Years ago I studied a course for Computer Technician. I finished it but I can't say i'm experienced in terms of computer.
But, i'm pretty sure I learned that when adding more rams, it is advisable we get the same brand/model.
Now I'm here double confirming if my memory is serving me right. The intro answered my question LOL.
Wow, actually someone who answered a relevant question. Great work and, love your build!
It's crazy how i had to watch 6-7 videos of 10+ mins each just to decide buying the same kit of x2 8gb i already had so i could upgrade from 16 to 32 gb ram, and then i decide to double check and watch 1 more video and find this, the exact same kit i bought, in a shorter video, better explained and with a relaxing voice.
Thank you man
Absolutely helpful. I got two pkgs of the same ram when I bought it, just because it was on sale. It was my first computer build in years. It used to be ok but wasn't aware of these other issues I started to learn about. So I thought I did something wrong. Your the first one to point this part out. Because like you I haven't seen anything wrong. And it loaded the XMP right out of the gate. After I turned it on. So thanks for the vid.
Amazing how technology has advanced and now does it all for you without having to apply too much if any effort at all. Over a decade ago I done something that wasn't recommended and mixed different speeds of ddr2 ram from different manufacturers to populate all the dim slots on my gigabyte mobo, my memory downclocked to the ram sticks with the slowest speed, my PC ran fine and surprisingly never crashed or blue screened when I thought it would.
ive done this with adata for several years now and always works fine 😅
glad there is a video about a Normal ram upgrade
That is correct, but you should also mention, that sometimes finding excatly same kit of RAM is very difficult, also in some country's if it is sold out "impossible". That's why in my opinion spending right away ( for example; double money ), and not ever worry if it will be enough, and spending time trying to find same kit, it's worth it getting more RAM than person currently needs.
Very informative and straight to the point. I recently did this 16 to 32 ram update and used the same kit as you. I like the low profile of the Vengeance ram.
I know I’m late but thanks so much for not adding fluff and getting straight to the point.
There is one important detail you left out. The ram you bought also comes in a 4x8gb kit, model number CMK32GX4M4B3200C16, which happens to be on your motherboard's QVL. If you're upgrading from 16gb to 32gb like this, make absolutely certain that the 4x8gb version of your kit is supported by your motherboard - sometimes its not.
How may I make sure of that tho…?
your motherboard manufacturer posts a pdf of the supported ram kits on the support section of there site@@misterhoudi2824
Can this be pinned to the top? I myself have purchased a second kit of 2x16Gb memory for it to fail like crazy. I just looked at the motherboard specs and sure enough, only 2 sticks are supported, making the other two just paperweights. I need to purchase very specific ram to get all four slots filled. Its pretty annoying.
Was looking for this exact situation. As this is what I'm running into. The only difference I saw on my sticks is the version on both sets. One is 3.32 and the other is 4.33 so I'm still not 100% sure if it's OK but looking at this, it should be fine.
i have the same kit and im too making it 32gb,my mobo doesnt support it at 2x8 and 4x8 but im currently running it for the past 4years 2x8 and its working ??
This is the exact info I was looking for, and from what I can tell it is the only video answering this on YT. You got a sub from here!
wow looking for about half an hour for a video that just explains it in a real scenario, always a small channel with the most helpful content 👍 saved me a lot of time
Great video! You helped a great deal as I'm the in the boat you were in. Thank you for being straight to the point with great info! You answered questions I had when upgrading RAM; I even have the same exact brand and model you have, though mine is 3000 MHz and red. But good to know that I can now comfortably purchase another 16 GB to add more RAM!
DDR4 is very forgiving. The main thing to remember is try to stick with the same kit if you can and if you cant then at least stick with the same speeds and timings.
Even now with prices for RAM super low a 4 DIMM kit is still expensive and even just getting two of the same 2 DIMM kits at the same time often will be cheaper, and in some cases could even be half the cost.
If you are adding ram in the future and can not find the exact same kit however you can mix kits but will have to be prepared for running everything at lower speeds or timings if the added kit does not match up to what it says it can do. So if your only option is to just buy another kit because your kit is not available any more make sure all of your ram is from well established venders as they will be more likely to preform to what is printed on the box. Though even then that may not be the case depending on your motherboard, CPU, and just getting unlucky. I had a 16gb kit of ADATA that was rated for 3000 but it only ran at 2666; still better then the DDR4 default of 2132 but not what is printed on the label either. You may also have to manually adjust everything if the kits do not match as XMP likely wont work correctly with mismatched kits
Also for those who are unaware DDR4 is only rated for 2132 which is the default. Anything higher then that is factory overclocked from the base standard. Additionally if you are looking in your system and you see a much lower number like 1600MHz that is correct as the printed number (3200 in this case) is double what the actual speed is as the DD stands for double density. Your BIOS should display the full number if you are using XMP though.
TMTR
This is exactly the question I was looking answers for. Thanks.
This is EXACTLY what im looking for. I want two ram in black and two in white. Same kit, speed, manufacturer, etc.
I did a bit of research on the topic. From my understanding, crucial memory would be the absolute safest bet for higher capacity ram kit upgrades. (Reason) Crucial makes their own ram chips (micron parent company to crucial)
As we all know, Corsair doesn't make ram chips. So for Corsair to guarantee that memory works for kits only indicates they use different chip manufacturers in each kit based on market price and availability. So the sub-timings can vary from chip manufacturers. That's when the average person can run into possible instability issues.
The solution: if memory is unstable for 3200MT/s for instance on two identically spec kits. Run them both at 3000MT/s as the speed and Sub timings should be matched by the motherboard. Validate in CPUZ that all Sub timings are the same and run a mem test through windows memory diagnostic at the minimum.
Also mixing capacity can cause potential issues, such as 32gb kit and 64gb kit to get a total of 96gb.
One kit may be single rank, while the other may be dual rank. This can cause an issue. Again two larger capacities can also have denser chips between modules, despite having the same brand timings ect. I think a more comprehensive video could be good for this channel. I do think buying identical kits by the manufacturer will yield good results 90% of the time.
I have mixed two of the same brand kits before and did have an issue once, and did have to step down the speed to a pre-defined timing on the motherboard. However i fo not overclock ram and play with timings as i dont have the time, no pun intended, to spend getting a fraction of an FPS when not being GPU bound.
What i would like to see is using same manufacturer, model, speed but with different sizes like 16GB kit(8+8 sticks) + 32GB kit(16+16 sticks).
Same question here
I did that with Trident Z 16gb and got the same speeds and Trident Z ram but with 32gb and used them together. PC saw all 48gb, XMP profile worked flawless and ran without issues for two years until I sold the PC.
As long as the timings etc are identical you can use a different capacity for each slot. So you could do 4gb 8gb 16gb and 32gb populating the four slots and have no performance issues.
@@nonaurbizniz7440 do you have to do them in that order 8gb 16gb 8 gb 16gb or you should do them 8gb 8gb 16gb 16gb? I assume first option is correct.
I'm doing this exact thing with my current build. I got a deal on two packs of 2 sticks for 4 sticks of total ram. I expect the XMP to work on the first boot, if not I will lower the ghz a little worst case scenario, with the XMP on. I've done this on past builds when getting a deal on PC parts. Just doing the best I can with my resources.
I upgraded to 32 Gb last year but I couldn't get the exact timings. But it is the same MFG and brand but what I had was 3200 and the other 16 Gb kit is 3400. Now I hated to do it but in this case I knew that it would all work but I would not see any of that 3400 performance because it will bring them all to the same sppeds and timings. But hey. Works greak. And it was Ripjaw by the way.
Different timings will work because the mobo will default to the lowest set. Ram can always be run slower than its rated speed and have no issues. Mixing different brands and timings tends to be an issue on oem workstation office type pc that are only compatible with certain timings and capacity. Dell and other major office pc makers do it to make the cheapest possible product. But if you buy any over the counter mobo from the typical vendors then they nearly all support mixing ram types and speeds.
I’m looking at doing the exact same thing. I have the exact same Corsair RAM kit and I’m also thinking of going with the second set as white like you as my case is white. My mother board is a bit older (MSI Z390), and I’m hoping adding more ram will help speed up my PC. Thanks for posting this video!
Thank you. None of these big channels I've seen discussed idetntial ram kits. It's crazy
You definitely can mix and match memory from different manufacturers. No harm to your system. I’ve done it on several occasions, and have never experienced any issues
I've mixed RAM from different manufacturers but DDR3, no issues to report.
You can mix rams with default settings, the problem comes when overclocking
been doing it ( not on gaming ) but on p.cs and laptops since windows 2000. I always new it wasnt the best. but not once have i had an issue. Except dell. Dell did NOT like anything other than dell.
I also bought the same kit 2 years later and ran into a ton of problems (BSOD frequently). Haven't nailed down if it's a problem with the newest kit or just a problem with the different kits working together. So it may just be hit or miss for everybody.
Hi there im experiencing the same thing. I have the exact same RAM kit too but i get BSOD. Tried memtest and it seems individually the ram doesnt have any problems but together, they keep getting errors. Have you found a solution for this?
@@nissa7825 Yep I just built my son a PC for Christmas and used the newest set of ram sticks. He's had no issues using them. Together in my system it was giving me BSOD. Really weird how that works. I never tested changing XMP profile but it could be an issue with that setting. I'm not sure though.
@@imhooks i see, thanks! Ive been trying and trying nonstop to get both of my RAM working smoothly and what worked for me was to set the DRAM Frequency in bios to 2400 MHz instead of 2666 MHz. Both of my RAM sticks were HyperX DDR4 2666 MHz 8gb (literally same everything except for the manufacture date i guess). So far i havent had any problems and it passed memtest too.
@@nissa7825 Yea I figured it was probably something to do with frequency and/or XMP profiles. Did you try setting it to 2400 restarting BIOS and set it back to 2666 at same time? Not that losing that 266mhz is going to make much of a noticeable difference.
Edit: This is something that I didn't think to try. I should have reset the DRAM settings in my BIOS prior to installing the second set. Then applying XMP profile on all 4. Instead I just installed the new ones and didn't make any changes.
@@imhooks nah i didnt try it anymore, I've been trying endlessly for days to get it to work properly that when I was able to make it work, I didnt wanna touch it anymore for fear of just messing everything up again lol (i'm not a pro in tech stuff and my field of expertise is far from it thats why im actually scared to touch stuff when its working properly)
But yea, I also found out only 1 of my RAMs had XMP which was kinda weird. In the end I just set XMP to auto and the only thing I changed was the DRAM Frequency
THANK YOU!!!!!!!! I'm in a pretty similar situation with the same RAM model and an MSI motherboard with 2 dual channel slots- the difference being that in my region there's not a single place online or physical where I could find an 8*2 ram kit, only single sticks are available now so I have to buy 2 identical ones.
Added 2x8 DDR4 3600 Corsair Vengeance to my existing 2x8 on my AMD B550 MB. Now have 32GB and all runs fine.
Does it run at 3600 Mhz?
Yes in fact it does. They were actually from the same batch by the numbers from MicroCenter. @@Focus_Fearless
This has always how I have done my upgrades. I buy how much I need when I build the pc, and double it later down the line as requirements grow. DDR3 was 8gb to 16gb, and DDR4 was 16gb to 32gb. The one caveat is that you should still try to keep the sticks as a pair, as mixing between the two sets can, but not always, cause issues. For example, kit #1 you might put in slots 1 and 3 to keep as a pair, and kit#2 you put in slots 2 and 4. A lot of kits will have some sort of version numbers on them so you can tell which set are a kit even if you get them mixed up. Worst comes to worst you can always swap between DIMM slots until it posts correctly.
thank you for this video man, the bit where you talked about other TH-camrs mixing completely different rams was so true it made me laugh
Awesome! Thanks! I had 2x16GB then I bought an X299X and bought a second set of 2x16GB and a 4x16GB kit. All the memories were the same G-Skill memory but I kept getting errors when running XMP. Only later I found out the QVL says that I can only populate 4 of the 8 sockets with that memory ... and that got me somewhat mad at myself. Memtest86 quickly showed errors when running the 8 sticks at 3200MT/s but the system is pretty stable at 2133MT/s. 2133 is somewhat slower, though ...
Oh, btw, 4 sticks used Micron ICs and the other 4 used Samsung ICs ... that got me mad at G-SKill!!! I'll check what happens if I use only 4 slots. My goal was to have a few VirtualBox machines running but it did not work that well, though. Thanks for the video!
The Takeaway is that you can Most certenly do this on DDR4 but it might very well be Diffrent story on DDR5. as you are very likely to run into issues with 2 identical kits if you enable XMP on DDR5. you might get lucky and it works but chances are slim as of right now at least. but you can just disable XMP and try your luck with manual setting the ram settings!
DDR5 on AM5 is super picky. My 7900X hates using 4 sticks of ram
I feel more confident now adding my old corsair vengeance 16gb 3600mhz to my current corsair vengeance 32gb 3600mhz.
Gonna go ahead & install it tomorrow. I will update this if all goes well.
You're mixing a 16GB kit with a 32GB kit? That might cause some issues
@@notanothertechreviewer yeah, 2 separate kits. I haven't got around to installing them yet, but from my understanding, they're identical other than memory size.
The motherboards manual suggests it should work fine. I may have to adjust my bios to get them working efficiently
@@connorwest465 As I mentioned in the video, it's best to go with kits that are 100% identical, and that includes memory size. However if all other specs are the same, you might still be OK. Hope it works out for you :)
@@connorwest465 hi, after one year, how's it going now ?
I think it goes without saying that the exact same model of RAM will work together, yeah.
When most people ask if they can mix RAM, usually it's whatever RAM they have and the cheapest RAM available, thus they'll probably use a different brand. Of course it will cause problem.
Good video, eitherway.
You just posted the video for the exact issue I was facing, now I wish I had the option to get white ram as well xD
Mine are same as you have but my 1st kit was 2x8 kit my 2cnd kit was 2x16 both were 3200mhz total of 48 gb Works fine. A & C channel has 2x16 kit B&D has the 2x8 kit. Bought 4 years apart .👍
Well I upgraded to the same ram same mhz same brand same cl16 3200 ddr4 just did 32gb instead and luckily that worked automatically which makes sense it's the same ram just more of it lol.
You will always have more issues adding 2 new on top aka 4 sticks instead of just using 2 ram sticks exact same but 32gb instead with 2 sticks.
The reason it worked for you is exactly why it did for me. It does auto and boom perfect.
I just bought the same kit of ram acouple days ago and it just arrived and i wanted to check if i could just plug it in thank you for answering.
Exactly what i needed, im gonna be saving money since its cheaper to buy 2 of the same kit here with sale and voucher going on thank you very much
GPU-Z is great. Have found many boards, even if you pick the XMP profile when leaving the timings to auto, on start-up the timings when checked in CPU-Z may be looser than the XMP profile. Recently added 2 additional sticks of Hyper Fury and discovered even though the sticks had identical timings at 3602 that was highest clock for one pair, whereas the 2nd pair had higher clock on 2nd XMP setting of 3730. Running the 2 pairs at 3600MHz without issue. As long as you run identical sticks in pairs and run at what speed and timings the weakest of the RAM can handle don't see much of an issue mixing and matching.
Have you stress-tested the kits? For example, even with just two channels populated from the same kit, I got memory errors on disabling and enabling the memory integrity option in Windows Security. I had to retrain the RAM modules by disabling Memory Context. This might sound irrelevant but one never knows where the problem hits.
bought a laptop recently and was looking at upgrading the ram - the 64GB kit is around £200 in the UK, whereas if I buy two single 32GB sims it works out to around £140!!! Insane and it'll probably be the exact same RAM!
Did it work for ya?
I've done this exact same thing and ran into nothing but problems. so your mileage may vary. I bought the exact same kit of ram for my system and the XMP will not even post. I am trying to figure out now how to get it to post and become stable.
It always comes down to what motherboard you have. The cheap AsRock B450 is very good with adding 2 more sticks even when using XMP.
thank you. thats what i was searchin for. great video

Same thing with me!
I had some money to burn so I upgraded from 16GB to 128GB... but all wasn't fun for me.
Reaching limits like that are a little dangerous. I had frequent and random crashes on Windows, with completely random error codes. Some OS corruption occurred but thankfully no data loss and a quick sfc command fixed my machine up.
The solution was to look at my CPU's specification, and limit the clock speed of the RAM to the maximum value on the specification.
I.e. 4x32GB sticks @3200 MHz with an Intel i9-10900k **must** be underclocked to 2933 MHz.
thnx for the advice. straight to the point thnx i bought it and no issues at all
Not always a fail-safe approach... you just got lucky: I bought the "exact same kit" too, 100% identical product name and model number (Corsair CMK16GX4M2B3200C16 - even in the same colour ;) )... then I found out it depends on how reliable the Vendor is.... after Corsair got lots of positive reviews on their Vengeance LPX 3200CL16 kits, they changed the underlying chips: there was a tiny label under the DDR4 label that changed: I think they were v4.xx and v5.xx.... up to v4 those had Samsung B-Die.... and the later models had SK Hynix. If I borrowed another Samsung B-Die kit, I could still run the rated XMP speeds, but if I tried the 4 sticks of Corsair CMK16GX4M2B3200C1 purchased a few months apart, it was very unstable to the point it couldn't even boot into Windows. I could run either of them at the rated speeds.... I just couldn't mix the Samsung and SK Hynix at the rated speeds, despite them being branded by Corsair as "the exact same kit".
I have a 2 stick 32gb ddr5 5600mhz vengence kit installed....went on amazon and REORDERED the same kit...and my pc wont boot. Keyboard doesnt turn on, nothing. The only difference I can see is that the "old" kit has ver 5 and the "new" kit says ver 4
Most these kits are not the name serial number even though the same product this could cause problems…
I did the same but I used 32 gig kits. I went from 32 to 64 with the exact same kit of DDR4 G.Skill 3600. Everything worked but the XMP would not take. The 3600 memory insisted on running at 2100. I didn't have good luck and you did. Oh well, it worked in another build I was doing so no loss really. I am at 32 gigs and staying there.
What is said in this video is mostly true, however I have a ryzen 9 5900x cpu and I'm running 2 separate identical kits of ram. The 2 identical kits i'm running on that cpu are the following speed, capacity, and timings. Each kit is a separate identical kit of 32GB 2x16GB 4000Mhz CL18. I have 2 identical kits installed and running right now. That makes a makeshift ram kit with 4 sticks of ram. So it then becomes 64GB 4x16GB 4000Mhz CL18. I can run just fine with one kit of that ram on my cpu. Then i when added the second kit of ram, my cpu then became extremely hard to get running smoothly. For not very many people 4000mhz with 2 sticks of ram with 32GB can run stably. Be it 2 kits of ram at that speed, amount, and timings. For smaller amount and speeds this method of mixing 2 identical ram kit would be fine like shown in the video. Similar things apply to DDR5 too, DDR5 ram is lot more picky about combining 2 separate identical ram kits. Therefore this video is mostly true. Just remember not to follow all advice you see on the internet. Sometimes that advice would be mostly true as in the case in this youtube video.
Legit had this exact question - thanks for the video
Thank you! I could not find a 128g kit of g-skill ddr5 6400 so I bought 2 64gig kits and assumed it should be fine. I have been looking for this answer for ever. You hear and see alot of mismatched ram etc but little to nothing of same kit ram. My 2 ram kits serial numbers are even in chronological order. Last 3 digits are, (197, 198 kit 1), (199 ,200 kit 2), so I got them all off the same line in chronological order which is awesome. So by the way you installed yours the first kit was in A2 and B2 for dual channel mode. And the second kit went into A1 and B1 instead of any random order even if they are all the same.
Hi,
It's great to hear about stability of having 4 sticks of ram, but what about the performance ? have you tried any benchmark and whether there's a little performance drop ?
Thank you for this, I did the exact same thing with the same Corsair sticks (only 2133 instead of 3200), but sadly your conclusion didn’t apply to me. My Motherboard recognised all sticks just fine and ran intensive games perfectly without any issues, but Chrome would randomly crash my PC and in general my PC would have random power shutdowns until my PSU would kick in and activate the safety measure. Eventually I even had a BSoD and couldn’t solve it without removing the 2 new sticks again. I ran the old 2x8 sticks for 4 years and never had any issues, so it was no coincidence. I thought the new 2x8 sticks may have been defect, but I decided to run my PC with just the new 2x8 sticks instead as a test, and more than a year later I have never had these issues again. Till this day I haven’t tried running the 4x8 config again because I’m scared to permanently brick my PC, and I still haven’t found any reason as to why 4x8 with two identical dual kits was not functioning flawlessly for me. Maybe I should try it again? Any ideas as to why I may have had these issues?
Hi, how's going ? have you solve your issue yet ?
I can't see any reason even before watching this video why adding in additional identical ram sticks will be an issue? What difference does it make if you install four sticks right away or add in two more later? None. It's like the industry standard for upgrades and why most mid to high end mobo have four slots to begin with so you can add more ram later if needed. There you go saved 6 minutes of your time!
What bothers me a bit is that rams that come in kits (of 2 or 4) have different part codes than single sticks of same product, I am thinking there is a slight chance that a kit of 4 might be tunned (or hand picked) in detail to have the exact same speed tolerance / variations, where 4 individual sticks of exact same product might have higher variations of frequencies / top speeds. They run at extreme speeds so I am thinking they are extra sensitive about running at exact same step.
Thank you for this video. I’ve been finding the same other videos
thanks for this video bro its very helpfull i have the same ram and i want to upgrade like u did great man
This is what I've been looking for.
Not so lucky here. Same Ryzen 5 3600 but using Corsair Vengeance LPX 3600MHz. Brought another exact kit to fill up the other 2 slots (A1, B1) and use it fine for like a month before I get random BSOD and random reboots. My motherboard QVL shows only support for 2x8GB for this Vengeance LPX, not 4x8GB. Wasted 16GB.
There might be some timings set to tight automaticly by your motherboard. For my experience but with DDR5 it were the tertiary timings with start which have the "dr" and "dd" (different rank / different dimm). My system wouldn't even boot with 4 dimms installed because it was automaticly set to tight. installed only 2 dimms and loosened them and after that i installed the other 2 dimms. After that i tightened them to the max.This maybe would work for you too.
i Went full yolo and combined a 32gb Kingston DDR5 6400cl32 with a Gskill DDR5 6600cl36 which i got gifted. Loosened all timings and started with 5400 which surprisingly worked. Then startet bumping all up and both kits are working together with 6000 cl30 and pretty tight subtimings at 1.45v. Both are A-Die Sk Hynix dimms and they can go really low on some timings. 6000 is the thery max my ROG z690f can handle with 4 dimms installed and that is pretty good to be honest and i might be very lucky that this does even work at all with 2 completly different dimms. I have to keep in mind that just resetting Cmos and installing booth kits didn't work. I had to make a very loose memory profile first and then install the second dimm because it automaticly set some timings to tight for it to train properly. Cheers!
I (literally 5mins ago, ironically) just put in 32GB of identical ram to my original 16GB, to make sure they worked. And the mobo didn't even revert from the docp profile either.
this is true for am4 motherboards with good memory controllers like that tomahawk but ive witnessed instances with ddr5 on am5 that will either not boot into the os, get a ram or cpu error light, or only run on base frequency (tested on 4x16gb of same brand, model and chip manufacturer).
My prebuilt came with 32gb ddr5. Just added another 32gb ddr5 two days ago and thankfully so far working fine. Had no messages upon boot up. 64gb total
Some quite switched-on comments below. One thing, I believe that if you mix different speeds & latencies, all the modules will default to the lowest spec, ie. 2x 2133 + 2x 3600 = 4x 2133, at least with DDR4. It might not even boot if you do that with DDR5, though - not used it, so far. But I've often mixed different capacity modules, at least on DDR4 laptops, either 4GB + 8GB or 8GB + 16GB, and that's never been a problem, you just get 12GB / 24GB, happy days!
I Purchased two identical 16GB kits of the same RAM as you running at 3200 CL-16-18-18 but now my system performs slightly worse then my 16GB 2133 CL 14 kit 😞
I keep hearing that memory controller is stressed when you have four sticks of ram filled. Is that true or false?
@Stefan Raab what if you left the 4 ram sticks at stock speed instead of the max speed?
Awesome video, Thank you!
I think I may be running the same memory as you. It's actually really good chance your running Samsung b-die; They are usually good at overclocking 3200 cl16 cranked up to 3800 cl14. Can't remember been a few years.
I took the same path as you, with the same Corsair kits. Also with no issues, once I enabled XMP. My only hesitation is whether, with all four slots populated, I should have put the two kits into the same channels, instead of dual channeling each kit. So if you did that you'd have your two white and two black DIMMS in adjacent instead of alternate slots. Would that provide any benefit over your (and my) current setup?
you can actually mix RAM from other manufacturers, you just need the same spd and timings. I had a 2x8gb from Avixer and just added 2x16gb from lexar, all are CL16 and 3200mhz all works great without issues.
I bought the same kit as was already fitted even making sure the part numbers matched but the first two were Samsung chips and the second two were Hynix.
This is what I was looking for. Thank you very much. I am now a new subscriber. Wonderful Video 🌈☕
THANK YOUUUUU i was looking for this 🙌🏽
Thank you very much for answering!!
I had to slow my 2x16gb 3600 cl 14-16-16-16-32 down to 3200 cl 16-18-18-18-36 with 2x(2x16gb) without crashing. maybe 1% performance drop in games but way better overall for my productivity work. just take the (barely) hit in performance if you need the extra ram. you will barely notice.
Kit have vers8on numbers, if same version, yes it ok.
If version difference, it could be because of different ram manufacturer chips...
You can also put in different ram chip brands, but depending on board option.
You may ha e to setup to your rams worst settings...
Like if you got 16 24 24 64, and 2nd kit , 18 26, 22, 74
So you put in 18 26,24,74 timings
Run mem86 plus pro , use 1 cpu only for testing.
(P.s if you don't run ram test (say 4 loops), Windows will still work, but it can cause stability issues, or corruption when you save data.
Ram is a confusing thing. Good video. 👍👏 I just put 4 dimms (2 kits, same manufacturer, same oem. Different age) into my Ryzen 2700x (linux server) and xmp 3200 didnt work, memtest found countless errors. So i switched manually to 3000 MHz, that seems to work. Happens with old Ryzens sometimes. The same dimms were running perfectly in an old I7 7700k build at xmp 3200. What i cant figure, the kit i switched back into the I7 didnt work with xmp 3200 also, even though it was running perfectly a year ago in this machine and in any other machine i tried. The heck😄
I can see in your video, that you where originally running your ram in dual channel. When you installed the extra Ram modules, you now have a "new" stick and an old stick connected in each channel. Do you know of it would be better/more stable to group the "new" sticks on one channel and the old sticks on the other channel?
the channels work with a space in between like that, so the new sticks ARE on one channel and the old ones are on the other
was hoping to see you mix different ram sizes from the same kit and see if that mattered, i have that exact ram kit but wanna get a 32 gig of two 16 gigs. would that work?
It should. Just remember to put it in dual channel config, they will run faster. It will have issues only above rated speed, and only possibly.
I read that sometimes you can have issues even ordering the same model/timings of RAM but a period of time apart from one another. I don't know how often this happens, but a number of other posters in the thread seemed to readily agree that even mixing the same brand/model/amount/timings can have issues if they aren't all from the same purchased box.
I am facing the same problem now.😁 I bought two single ram sticks at different times with the same specs except manufactured year and serial number ( not model number)..
With my new Ram nothing works..be it individually or together with the old Ram..
Old ram alone in any ram slot works perfectly but not the new ram stick
@@rockr8840 If it doesn't work alone, or with the new ram, try to RMA it.
@@krnldude I have already returned and got refunded.. bought a new Ram from Corsair vengeance RGB series
@@rockr8840 Great! Very fast replying lol.
The main actual takeaway is that mixing will work if you default to the looser speed and timings. Its more beneficial to have identical amounts on each dtick.
Thanks for the advice!
I do the same thing today. corsair vengeance 3200. 32gb to 64gb. past the kit i have before in slot 1 and 2, and the new one in slot 3 and 4. 64gb total. same ram brand reference etc. But now in slot 1 and 2 they are in sngle mode, but in 3 and 4 dual channel. How i can get all in dual chanel? tks
If you buy the same one there is still no guarantee that they are the exact same memory chips under the headspreader, what makes the matter worse is that the company selling you these "never validated these for 4x8GB" even tough they might sell a similar kit? Well if the "similar kit" has higher CAS you could manually adjust them to the 4x8GB kit XMP settings and if they are indeed same memory chips it should work.
I was under the impression that you have to keep each pair of ram kits to its own channel memory. But what you have shown here is the ram kits split into two different channels for both. Cause slots 2, 4 are two different channels and 1,3 are two different channels and you have the two different kits paired with each other in each memory channel. I have had ingame crashing issues and i noticed the two middle slots of ram 2,3 are much higher temps than the outside slots 1,4 so i will try your way and see if the heat in 2,3 slots is still higher maybe the overheating is causing the crash cause it happens after like 2+ hrs of gaming.
You can use any brand as long as its the same ddr and mhz
I have purchased the exact same Kingston fury beast cl17 3600 ram and it doesn't work stable with 4 sticks at 3600mhz only at 3000mhz xmp. This is not an absolute . Maybe with Corsair. Either set works individually at 3600 in a1 and B1. I'm going to try a matching set in a1/2 and same again b1/2 fingers crossed I can get full speed.
Is it okay to add dual channel 2x8gb (3600 CL18) to my existing 2x8gb (3733 Cl17)?
it is the same brand and even product number just different speed and timing.
I just use around 3200 ram speed in xmp.
i had 2x 4GB Adata DDR4 2600, 288 pin sticks, to add 2 more the exact same would have cost me 200$. Turns out G.Skill Ripjaw makes the exact same ram for 50$ so i bought that, been mix matched for 5 years with no issue. Literally the same ram made in the same factory with different heatsinks and different price. Both casings metalic red btw.
I have the same brand, the same speeds and the same timings but they have different sizes. I took a friend's advice on mixing ram sizes, just as long as the speeds, timing are the same... The Ram arrived today, and I am scared to install it with the old stuff still in there. I most likely will remove the 16GB kit and install the 32GB kit. And then buy another 32GB kit in a couple of weeks.
What software can I use to test my ram? Make sure the timing and everything is working? Also great video ty much.
What about DDR4 16 GB (2 x 8 GB) 3200 MHz CL 16 Corsair LPX and DDR4 64 GB (2 x 32 GB) 3200 MHz CL 16 Corsair LPX together for a total of 80 GB? Do you think it could work?
so can I use my Corsair vengeance pros with my new Corsair vengeance pros? they the same speed n everything else the only difference is my old ram sticks are taller then my new ones.. will that be a issue even tho they the exact same?
