Videos like these are WHY I watch this channel. "Screw it, lets see if it works" is basically the origin of scientific practice. This is the kind of argument tech nerds have been having for years, and most people don't have the hardware stash to actually test this kind of thing out properly. I love this kind of "lets find out together" approach, and appreciate that the "well that isn't how that was supposed to work" moments don't end up cut out and only in some private bloopers group chat or something.
Agree
Great comment! Totally agree. These episodes are also very entertaining. More videos like these, please!
"the difference between science and screwing around is writing it down"
in this case, documenting it in a video form
The "well that isn't how that was supposed to work" moments
is the only reason to watch most of these types of videos
oh and the memes ofc
Great video and great comment @Samebito. I totally agree. I also remember watching a few months ago a similar video, about using mismatched memory on LTT. However, I think Jay'z approach is more in depth and more explanatory . Very happy he did a follow up video.
That video can be summed up with a quote from Christopher Titus: "I don't fail, I succeed at finding what doesn't work." And to be honest, it answered a lot of questions I had about RAM speeds and timings, so it's definitely not a waste. It was educational, it was entertaining, it was JTC.
I'd love to see this exact test with the AMD bench, considering AMD seems much pickier with its memory speeds
sadly amd is picky i guess intel doesnt care
Yes. This.
This!
Yes
early on it mostly had to do with XMP and some of the settings in it that don't work with AMD's memory controller(that's changed over the years since first gen Ryzen released). the interesting thing is that if you manually set all the XMP timings they'll work fine, enable XMP and sometimes they don't work.. the other thing is that running 1.38v instead of 1.35v seems to solve most of the memory compatibility issues especially if you're using hynix memory modules.
I remember EDO RAM where you would have 4 slots but only 2 banks, it would make the lager stick come down to the smaller one. If you put in a 16MB and a 32MB in the same bank you only had 32MB total (16 x 2). I learned the hard way because the first time I built my own PC it was on a Socket 7 platform.
Don't forget about ranks if you're going to get into the whole number of dimms conversation
That's where 4 single rank and 2 dual rank sticks at the same speeds technically perform the same, right?
@@jamesiepooh7337 yes but 2 dual rank is generally preferred
@@whoisthatthingwhat @James DeHart I can't find any information on 8GB Corsair Vengeance RGB Pro DDR4-3200mhz. Is it dual rank or single rank? I've read somewhere that 4 and 8 GB are usually single rank, but 16 or higher is dual rank. It doesn't seem right to me.
@@peterletran single rank
@@peterletran 4 and 8gb are almost always single rank, with the exception of old 2 x 8 kits using something like 2015 Samsung E die. Nowadays some 16gb sticks (2x16gb) can also be single ranked, I know some Micron for sure and probably Hynix as well. The Corsair kit you speak of will almost definitely be single rank and could be any number of different IC's including but not limited to Hynix (Corsair Version no. 5.31-5.48) CJR, DJR, JJR and Micron (or Spectek made micron IC's Version no 3.31-3.34) Rev E and J
It's fun, watching the logical part of Jay's brain melting down when hardware just decides to say "fuck it" and do whatever the hell it feels like...
As for the oddest amount of RAM I've used recently, I ran 56GB a couple months ago (3x16 1x8) while I waited for a stick to replace one that failed. I had a 8 stick laying around and for my workflow the 56 setup was faster than the 32 2 stick and the 48 3 stick, not a lot faster but every bit helps.
Jay is so old that he remembers when his 2 cents were worth a nickel. /s
Love this channel.
I always used mismatched ram, no complaints. Just needed to set as slowest...
Only thing to give headache was to mix single sided ram with double sided... either didn't work, or didn't recognize all of it or didn't enabled dual channel.
HAHAHAHA! This is the greatest channel. An unbelievable source of ridiculously useful, common sense information with a nice humble comedic flare. I’m a mechanic and that whole Honda Fit turbo to supercharger bit was great! I was freaking dying! Keep up the good work
Yo Jay, That ‘Office’ Reference Was GOLDEN!!!
🤣🤣 U shld use more analogies of funny crap like that… love to hear one on animals or politics 😂
Hah! Love this. Excellent video.
Gotta say though, with modern day mem controllers, you will still start seeing performance losses on larger capacity setups.
Ram virtualization makes a lot of these mismatched setups not only possible, but even perform decently. It might make boot times a bit slower, but I'm not even sure you'd see a human measurable difference.
Capacity will create a difference though.
If you go from 16 gig to 32 gig, no big deal.
From 4x8 sticks at cl16 to 4x16 sticks at cl16, you'll start seeing a lot more heat from the memory controller.
At 4x32 @cl16, if you can get it to boot without lowering timings, your memory controller will absolutely hate you.
Obviously this is with a standard dual channel currently Ryzen or Intel Z490 chipset.
Server applications and higher dim/channel capacities will see the same type of response though.
You’re going to have to test higher speeds with mismatched timings as well as mismatched capacities for the heck of it. It would also be interesting to see how a matched set of 4 sticks would compare to a mismatched set of 4 where the lowest stick is a stick of the matched set.
This makes me a little happy to see that my purchase of CL14 (14-14-14-34, 67 Clocks) makes a difference. :-D
I'd love to see a video on manually setting ram timings etc. I still use an older system (2600k and 32 GB ram) that runs just fine. Going over ram timings is a chore to find decent info on.
Love the fun you guys have too.
Yes, this
It's really not that hard to find good info. There's plenty of channels just on TH-cam with good videos explaining ram timings. BuildZoid has a series explaining some of the basics on ram and such, GN has had part one of their ram explanation out for a couple years at this point I think, can't remember the specifics now.
@@NotThatGuyJD Thanks
Timings are a complex topic. Sometimes loosened secondary timings prove an improvement, because they let the rest of the timings work better together.
It is a sign that tinkering with the secondary and ternary timings can be adjusted to perform even better on the tighter primary timings.
Back in the day I had a machine with 384MB of RAM. (256+128).
It was a Pentium 2 that came from the store with FOUR MEGABYTES and Windows 95. I slapped another 4MB out of the shelf, and then spent years upgrading it.
It ended with 384MB and Windows XP, still running smoothly after I REPASTED it, the thermal paste had crumbled to dust.
From 4 to 384. Nothing else had such a upgrade in the history of anything, ever.
Imagine a MOPED with 4HP. You upgrade it until it has 384HP and can rip burnouts at 100mph.

My old out of warranty MB B channel stopped working. When I upgraded, I replaced the two sticks with a larger size. I just used those old two sticks later in a media PC I built. I needed more RAM for media art 2D and 3D stuff. My MB also supports RAM cache for the storage.
In college my professor wouldn't even use RAM that was from different lots
That professor is a dunce.
@@CompproB237 back in the day, you had to be that picky. So.. he's just set in his old ways
Phil and Nic dying in the background made this video epic.
Jay Patriot make some very good memory. Their Viper Steel series is great for overclocking and is cheap for high frequencies.
I used to have, on each channel, matched memory, but unmatched channel vs channel. It worked very well, and this was on an older setup. But since the CPU is the one that actually handles the memory, I figured, it would just do the best it could do, in each memory controller/channel
In my previous system I had 2x4GB and added 2x8GB for a total of 24GB. Simply the added capacity made it perform much better.
Yes do a timings video. I'm about to get 64gb for my girlfriends pc and would love to know if 3600 with a little looser timing is worth more money or if it'd be better to get 3000
In my case about the same. Don't recall the specs exactly for the ram, but 4x8 @3000 vs 2x32 @ 3600. Very very close scores on firestrike and cinebench23.
This with a 3900x on a msi b540 tomahawk max.
depends on the system setup whether it's AMD or Intel since there is a slight performance increase running 3600 over 3000 that may offset the performance loss due to timing and what the systems being used for.. it's likely that overall there's no significant benefit to running 64x3600 vs 64x3000 but saving a couple 100 dollars might be worth it.
I just built a top end pc and felt/feel I overspent on the ram. Feel a little bit better now. Paired an AMD 5900x with 4 sticks of Trident z Royale 16gb 3600mhz 14 14 14 34. Going to running some benchmarks now.
@@tchlin it pains me to see you buying overpriced ram and not manually overclocking it.
@@whoisthatthingwhat if I ever understood subtimings properly I'd probably do all manual overclocks. For some reason I enjoy tuning things more than actually using them.
my first pc was 1x1GB ddr2 667 + 1x2GB ddr2 800 and it ran pretty well for a budget build. the aging hard drive that caused lockups unless actively cooled was more of a performance issue than tjw ram.
my current rig has 2x4GB 1866mhz hyperx and 1x8GB 1600mhz xms3 salvaged from my fx3200 rig. i think it's 8GB per channel so should be fully dual channel rather than just the first 8
im running 48gb of 2133@1770 9-11-11-27 cr1 in this old 1366 rig, when my crosshair v-z died my uncle gave me his old 1366 rig, and i replaced the 12gb ram with 32gb i had from the ch v-z and was able to get 1 more matched kit for $99 by luck, replaced the i7 920 with an x5675@4.42-4.65ghz for 20bucks... not bad... for a decade old rig... primocache helps with load times alot...
I have a 10+ year old i7 970 Dell XPS 9100 that's running 36GB of ram. Triple channel ram, 3 sticks of 8GB DDR3, two from a couple years ago and one from a friend (all the same brand/line in name, but definitely not actually the same) and 3 original sticks of 4GB DDR3. Runs completely fine and I only upgraded the whole system this year after the GPU kicked the bucket.

The importance of CAS latency over frequency was established a long time ago. Glad to see nothing has changed.
I think buildzoid needs to tech jay about b die, cjr/djr, micron revs. Just just went full mormy. Does jay know about ram ranks?
Yep, but in the general sense that just contributes to a particular set (or stick) of ram being able to achieve tighter timings. He showed that today without losing a lot of the more casual users with technical jargon.
This video is a nightmare. I'm gonna have to stop trying to explain to redditors how RAM works, because they're gonna keep referencing this monstrosity. Jay is way too big to be putting out a video about something he's THIS uninformed about.
Total agree on this. This did
Happen to me i bought the same ram didn't see the timing but same speed. Had this problem couple of time than just bought another set than have no issue.After looking at the timing had to be the same than it works great.
One of my experiences with XMP out of many is that it does not always work.
To get one confirmation to work I had to disable XMP and manually set the timings plus set the power requirements for the ram.
I think xmp was not working because power requirements were not being met
You should also make sure that when XMP is off the RAM is running at the actual DDR4 voltage - 1.2 Volt. It can surprisingly have a noticeable impact (iirc the memory controller is part of PL1/2)
Also:
No, not "everything over 2133 is an overclock". DDR4 is specified all the way up to 3200 - but those dies are rare and cost a LOT.
I've always gone for low lattency ram... and my computers have always been super fast. Sooo many people dont look at timing at all, but its more important than most ppl realize.
When the 4 sticks test (with 2 pairs of different fimms) worked betther than the XMP ON dual initial setup; It would had been a good test to do 4 identical sticks XMP ON test. Just to see if, for any reason, the CPU score of the 3DMark was heavily influenced by the total capacity of RAM.
I have 56gbs of ram in my rig. It's an 32gb kit and 2 separate single sticks that I ripped out of my previous 2 Walmart prebuilts... runs amazing somehow. When I get home I'm going to run the bench 🤣

My takeaway is that from now on I will be paying more attention to timings on my ram kits.
A set up I often hear is having 2z4 stick (8GB) at the start and now adding 2x8 sticks, ending up with 24GB. It's good to expect no real problems (and significant improvement) as long as the speed & timings can match!
I'd say you can run mismatched just fine as long as the timings and speeds are the same. The voltage should standard for the most part.
Yeah, 24GB here. 2x8 (Crucial Ballistics) and 2x4 (Kingston HyperX), but that's still DDR3 1600MHz. Both kits run smootlhy together at 1866MHz. They do run even at ~2GHz without issues in Cinebench or other benchmarks, but after a long times of running somehow PC had issues with booting up again, so I've lowered it back to safe values.
Runs fine till I decide if I want an ok gaming rig or workstation capable of photo editing while running VMs in background.
Did you check the number of ranks in each module? I feel that could be the major contributing factor to getting more performance from "moar RAM".
If the original DIMM only has 1 rank, having 2 of them per channel (or swapping for a 2R module) should improve the performance noticeably.
*
Intel works fine with unbalanced RAM configurations. The CPU will use any amount available on every channel in dual channel, then add any leftover as single channel memory. The system should also be smart enough to only use the dual channel area if it's enough.
id like to see the long term stability of the system tho. it all well and fine doing a quick benchmark. but who knows what would happen in the long term
I don’t think that the last one just working is surprising. I do this regularly with DDR2 on test motherboards: I just grab random sticks from my RAM box and use them. Usually works.
Of course, it’s not the optimal performance for obvious reasons but who cares, it’s DDR2 and I just need something to test a hard drive.
I thought it was anything over the IMC's rated speed was considered an OC, not that anything over a fixed memory speed was considered an OC. Like Coffee Lake has a max operating memory speed of 2666MHz, anything above that is considered an OC for those chips. But Comet Lake it's 2933MHz, and Rocket Lake is 3200MHz
I’m running mixed RAM. My first RAM kit is Corsair Vengeance LPX 3000MHz cl15 2x4GB, second is GSkill Trident Z RGB 3200MHz cl16 2x8GB. Totally 24GB running at 3200MHz cl16. Everything runs smooth. :)
Ryzen 5 3600, golden silicon runs at 4.2GHz@1.1v, B350-F latest bios, thx 1070 msi gaming x.
For Science!!
The only DDR4 I have is the kit in my Ryzen build (8GBx4 3200 16,18,18,36), but I've still got an X58 rig with its 6x slots. I've got 2x packs of 2GBx3 in it, but I've got an 8GBx2 pair from another build I could play with. 24GB might be doable there, but I doubt I'll get anywhere close :-D
I used to have an old PC about a decade ago that was really weird. It was DDR 3 intel board, and would boot up fine with 2, 4, 8 and 12 GB of ram, but it would not post what so ever with 16 GB, however it booted and ran fine with 24 GB. This was all done using the same sets of ram in various configurations.
Definitely wanna see more (maybe try 2133 or 2400 MHz and get timings as low as possible?), but I'm guessing that TridentZ RGB would have handled the timings of that mismatch x4 setup if it was also at that same clock speed of 2400MHz. Also, you should do more tests with games (ideally ones more memory dependent) and maybe leave Cinebench out since it doesn't seem to be memory sensitive.
My old Pentium 4 was running a 1+2 GB combo for years and had nothing wrong with it and my current PC is running a 8 GB (2400 MHz) + 4 GB (2132 MHz) and also runs fine. I never cared about RAM matching because more memory was better for performance than less memory but matched from experience (if you actually use it fully).
Let me explain:
When Jay added 2 more sticks, the channels had DUAL RANK, which is faster than single ranked config.
When Jay removed 1 stick (3 total), one channel still had a dual rank config, while the other was single rank, still some benefits to one channel. The CB score might have been higher with 3 sticks because it's easier on the IMC.
When Jay had 4 sticks at 2400 Mhz, there are still benefits to dual rank, yet the frequency was too low, hence the bad 3Dmark score. CB doesn't care as much about frequency, and it being very low, was pretty light on the IMC.
yes please! talk about memory timing in a video! i need to learn what whats!
I was running 48GB of a 32 and 16 gb g.skill kits. The 16 was way slower though, 3200 kit vs a 3800 kit. The 3800s could go and sit at 14-14-14-34 at 3200. Maybe even tighter. I havent tried yet. So now only running 32gigs at those timings, under a 5800X on a X470 Prime pro.
And yes! Please a video on timing tuning.
So I have an older system in my little collection that has 15gb of DDR3(1gb, 2gb, 4gb, 8gb), But I've known that mixing and matching ram "works" for a long time. The first 486 I built for myself was a jumble of parts I rescued from my uncles junk bin..... He was surprised it ever worked at all.
I had a Ryzen 2200G rig in my office that I used for research. I had 16 GB (2x8GB 3000 MHz Corsair Vengance) running at 2933 MHz (the max I could get with XMP enabled and no other tweaking) and got a Geekbench multicore/single core scores of 3247/940. I pulled it and put in 32 GB of 3200 MHz memory (which would not run faster than 2133 MHz due to the memory controller on the CPU) and low and behold, the Geekbench scores dropped to 3080/935. It is interesting to me that the multicore score took a much bigger hit than single core!
At any rate, I replaced the CPU with a 4650G and am now able to run with 32 GB at 3200 MHz, anf am getting Geekbench scores of 7295/1229. I can't wait to put linux on that rig and get back to some computational chemistry!
The thing is Intel can innovate the mem controller (and everything else on their motherboards) while AMD is very limited on what they can change since they pigeon holed themselves into using the same chipset socket for over half a decade (AM4 & again when AM5 launches). That is why Ryzen has been and will always be lacking in the memory department, because of their insistence on backwards compatibility.
Another case where capacity matters more is when Windows has too little memory and starts to slow down. I had some mismatched cheapo sticks lying around and just chucked them in, and after swapping some around in the memory slots it would work fine - and Windows was much happier with almost twice the memory.
How do you get those mismatched sticks? Upgrade RAM or whole PC's for family and gather up all the sticks that are left over (I tend to throw out the Dell and HP assembly line PCs but keep the memory sticks. These tend to contain just one stick).
On the other hand, I have had horrible luck with high-end memory kits: one 4 dimm kit would not boot at all in my Asus ROG something something (8 years ago), one would work but not at the advertised memory timings. More recently I have run some G.Skill Trident Z 3200MHz on my Ryzen system which ran fine, then I upgraded to Corsair 4000MHz which don't play nice: Above 3600MHz the infinity fabric and memory bus go asynchronous and I could not get it stable (I should have done more reading before buying). But even at 3600MHz stability is a problem in some scenario's... :(
Jay there was never a time that you couldn't use mismatched RAM. It was only an issue after XMP and that's because of the XMP profiles if you enabled them rather than the old fashioned manual tuning that had to be done to get the speed and timings that were on the sticker.
I run a dual CPU Xeon server as a gaming rig, Still on DDR3, I got a set of 1866mhz on one CPU and 2400mhz on the other, but the server is only able to do 1333mhz anyway and the RAM plays well together so I left it alone.
Hey Jay, Great video, I have Patriot Steel 4x8GB 4000mhz, CL 19, 19, 19, 39 can only run 2 on Asus X570 Tuf. I have Ryzen 7 3700X, RTX3060TI. I have struggled to run 4 at XMP 2 3866. I have tried watching videos to see about manual timings but nothing works, i have used Typhoon Burner and Dram calculator but with no success. After watching this video i decided to add my Crucial Ballistix from my test bench 2x8GB 3600 CL16, 18, 18, 38. I have the 4000 in B and 3600 in A. I enabled XMP and system booted ok, CPUZ states 32GB at 1799.6Mhz Timings 16, 18, 18, 38 Command rate 1T. However CPUZ slot 1 Crucial XMP 3602, Slot 2 Crucial XMP 3602, Slot 3 Patriot XMP 3868, Slot 4 Patriot XMP 3868. Not sure what it all means except different manufacturer and ram size works. My Time Spy overall is 11416, GPU 11662, CPU 10202. Please more content on Ram timings and mixed manufacturers please
I tested my memory in my R9-5950X with 128GB 4x32 Corsair LPX 3200 system, both at 2133 and 3200, and the memory benchmarks at 3200 are actually slower than the 2133, because the timings go up from 15 15 15 36 to 22 22 22 53. I would have to mess around with individual BIOS settings to probably try to tighten up the 3200, which is just not worth it.
My favorite part of all of JTC’s videos are hearing Phil occasionally explode with laughter off screen.
Since timings are measured in ticks of the frequency, these are exactly the same in terms of latency (measured in time):
3000 MT/s C15
1500 MHz frequency
15 / (1500×10⁶ s⁻¹) = 10×10⁻⁹ s = 10 ns
3200 MT/s CL16
1600 MHz frequency
16 / (1600×10⁶ s⁻¹) = 10×10⁻⁹ s = 10 ns
3600 MT/s CL18
1800 MHz frequency
18 / (1800×10⁶ s⁻¹) = 10×10⁻⁹ s = 10 ns
That's why the high frequency DIMMs with lower timings are so expensive - more mainstream modules are genuinely unable to run the chips at such extremes (even 3600 MT/s CL16 would be 8.89 ms).
I have a HP Prebuilt bought it from work, it has a I5 6500 , a quadra M2000 and 3 8gb ram 2400mhz, 2 of them with hynix chips and one with samsung (HP memory no heat sink), my use case is not that much for gaming but for photo editing so the memory counts
Should try this with one of the laptops that have soldered memory with one open slot to find fastest configuration.
I once build a system on the X58 platform with 17 gb RAM... 3x4+2x2+1x1 - only to see if it would have better 1% lows than just the 3x4gb, at the same speed and timings... it was not, it was more or less the same... with a X5675@4,45 and a GTX 1070ti...
Back with ddr 2/3 I used to go for fastest timings available.. This setup with ddr 4 is more of reasonably high speed (3200 iirc) and affordable price to get 4x 16gb "kit" (actually 2+2 kits). Went for the 64gb because I sometimes run some rendering jobs and back when I had my best ddr 3 setup with fast 32gb, some rendering jobs ate 100% of available memory.. and that was before I tried to work solely with photoreaslistic renders. :p
I actually run 24 GB on my Alienware 51m, I put the two same RAMs on Channel 1 and the other RAM on Channel 2; the other one is very similar but not the same and it works pretty well. It had a positive effect for Star Citizen and everything else has appeared to be same. Probably a little different, but it had positive seen effects instead of negative seen effects. For me it was just an extra stick I had and I said; screw it, let us see what happens, and it worked out
Simply toggling XMP was a headache for me because it started to crash my games and I couldn't figure out why for months. Come to find out the default XMP profile wasnt giving my RAM enough voltage.
Getting close to then end of build as i finally found the big 3 i needed CPU/GPU/MB. Was looking at 4 stickers of slower 3600 ram instead of going up to the 4000/4400 mhz ram cause i can't afford 4 sticks of the faster memory. Would be interested to see how to figure out where to best spend my money as i don't have the ability to upgrade often so this will last me 5-8 years unless something drastic changes. Thanks in advance and keep up the great work!
My first thought when you took the first GSkill stick out and it improved was that the stick was at the bottom of the "silicon lottery" or maybe not set correctly. I still think that something like that was the case.
Yup I went with 8 sticks of 3600 1515 15 xx TridentZ on my TR had to increase voltage to my SoC but it runs perfect. Had to mildly increase 2nother voltages. On the old P4, 4 mixed match sticks ram better than less... Im certain the P4 would had preferred matched RAM with tight timings better of course but I was broke and in HS LOL. My AMD's have always liked fast high quality RAM woth tight timings all channels filled.
For me to get another match 32GB set it will be $400ish dollars and it's for 2400mHz c10 DDR4. I really have been on the fence on getting another set since I know it will default to my 2400 but I know the timings wont be anywhere near the Dom Plat set.
back in the pentium 4 days, i had 4 mixed sticks of 1GB each. but to get it to run, i had to put each stick into the correct spot in the correct order and boot in between.
but in the end, it worked and that counts :D
Not all motherboards will default to the lower XMP profile speed. Some will read from a particular dimm slot first. Eg x99 soc champion
interesting outcome. As said in the last vid corsair 2x4-2x8gb's all 4 out of the box @ 2133mh/z 24gb's, still fine for my gaming. Well at least i think ;pit runs & works so.
I finally got annoyed enough at 16GB @ 3200 not being enough capacity for all my browser tabs... that I recently pulled my old 16GB @ 2400 kit out of an old rig, and now have 32GB running @ 2666... no issues. even ran well at 3000 speed (with that 2400 ballistix kit) until I ran into an error a month later that may or may not have had to do with RAM... but set it to 2666 to be safe.
Mine is just a simple 2x8GB config on a B450M-DS3H (Ryzen 5 1600). My RAM is the Corsair CMK16GX4M2E3200C16 which I know I can easily find if I want to get more RAM, but for now, I am far from utilizing 16GB of RAM.
you've done videos on overclocking cpu and gpu, can you do a video on how to overclock or at least tweak ram?
Cinebench only uses like 2.5GB of RAM. I guess games, using more than 10GB (or even more than 16GB) RAM, might show bigger differences than these benchmarks, if the memory can't be distributed evenly between the sticks or channels.
Maybe not that common, but for years i was running 8x4gb 2133mhz sticks with oc to 2666mhz after some bios update with my 5820k. Today it is working 2x16gb 3200mhz sticks running at max speed of 2666mhz (my mobo doesn`t like more)
My AMD 5800x system is running 32gb of slightly mismatched 3600 16-16-16-36 (2x8gb kits with same timings and speed with xmp enabled, both are g.skill trident z; one kit is RGB the other isn't).
This is the kind of quality content I subscribe for 😂 I've been running mismatched ram for a while with lowered frequency and tighter timing. It's a weird world
Been learning from ya for years my dude! Please continue this with timings!
Well thanks, this lead me to check the RAM sticks I had sitting around, all specs matched other than capacity, slid them in and hey, it was free real estate!
Science Fell in Love, So I Tried to Prove It
GN Steve & HUB Steve are either weeping or laughing somewhere.
I have 28 GB in my NAS/server. Older dual xeon workstation (X5670 s). Came with 12 Gb in 6x2GB. Found a couple 8GB kits. And boom, 28 GB of ram
That mobo flex when he puts the ram in :D push Jay push
I have x2 16gb Corsair vengeance 3000 dual channel & x2 sinba (Leven) 16gb 3200 single channel! Somehow after much messing with timings all run at 3200 stable.
19:41 Well I'm guessing it's lower not because of the mismatch but because it's running at 2400Mhz
Hehe, i was very surprised when I had to send my 2*8Gb DDR4 3600 Ram Kit to RMA and had to put a single 16Gb DDR4 3600 from my brother in law in... The speed of my 5600x didn't change as much as I expected.
Maybe have something to do with the 2*8Gb Kit be Singlerank and the single 16b Stick being Dualrank.
Was impressed tbh.
I have 24 GB of RAM, but both sticks are the same XPG brand/type with same speed and timings. Only the outside color is mismatched (oops). I could even lower the timings a little after running DRAM Calculator for Ryzen. It's been running fine for months at 3600 MHz CL 16-19-16-36.
JAY! just got around to watching this video about a week late... You asked for weird memory setups. My laptop (Asus tuf A17) reports 15 gigs of ram. My Proxmox setup (amd 3950, GTX 1050ti, with 98 gigs of mismatched elcheapo ram) is even more off the wall, it reports 94.33 gigs of ram available to virtual systems. The laptop yeah I run it hot, that's my fault. The home lab is intentional. I don't need performance on a virtual machine where frame rate is bottle necked over a wifi connection. I do however run a few virtual machines each getting their own section of ram for stability. The NAS wants it's chunk, plex gets a portion and has PCI passthrough, openvpn on pfsense for remote security, and even a local mysql server for local projects. The use case for mismatched memory isn't always speed. Sometimes you just need to run all the things.
I have 80GB in an i3-10100 :-) running as my server. The bios absolutely cannot figure out the timings with the crucial+corsair mix, and I had to set timings from datasheets.
Anyone else notice in the redux ad the sticker on the cooler master fan? That things wobbling more than i was on my 21st birthday!
FYI, the new Honda fit comes with 1.2ltr turbo charges engine.
I have a r7 2700x, using 4 sticks of same capacity Corsair vengeance pro ram... Different timings and speeds ( didn't read when I bought the 2nd one :( ).
Worked fine at first. Xmp is not an option. I had to manually "overclock" the slower card. Well apparently they are different manufacturers for the 2 sets, and the sk hynix brand DOESNT like that. So I'd blue screen left and right. If I understood how to deep delve tweak ram, I think I could get a decent result. As it stands, they work, but I'd like to optimize it.
Side note, on my fx6350, I had a 8 gb, a 2, and 2 4gb sticks. Recognized them all and played beautifully at 900mhz (1800) on a ASRock pro something board. The 2 4gb were ripjaw, other was a crucial, and the other a Corsair.
Intel: It just works.
Wait… something seems off.
Not weird as such, just unnecessary.
96GB. 2x 16GB and 2x 32GB.
Basically I got the 2x 16GB which is enough, but my OCD wanted all 4 slots taken to look nice with RGB.
So I went to buy another pair of 16GB for a price of £150 which was the original cost, but then as I ordered them they went out of stock and the next sticks costed £210. I thought, well F it I will get a 64GB kit for £300 and if I need to I will sell the 64GB or 32GB kit in the future if I upgrade to DDR5.
So I have 96GB of RAM and no, the performance did not change at all, Cinebench score was the same, 3D mark was the same and all my games ran at the exact FPS. No performance hit at all.
whoa whoa whoa! you never tried to enable xmp with the mismatched 4!! they had a good timing bracket! it might have worked!!!
