I have AMD build same problem with the Asus Tuf X670E motherboard first dual (kingstom ram 2×16) channel works on 6000mhz. But if use 4 dual channel it not boot up to windows. Strange things is you can see and hear fans spinning plus all ram have rbg light up but black screen. So issue is not the ram stick but need a firmware update ???
I built a 12900KS with the ProArt Z690 and 128GB of DDR5. As you highlighted in this video, I had continuous issues trying to get the sticks to operate at anything above base clock. The system would refuse to POST and usually required me to remove the other two sticks of RAM before it would even boot again. Every time a new BIOS version was released for that board. I immediately installed it, hoping it would correct the issues, but it never did, to include the very latest version with 13th Gen support. I dropped everything on eBay and built a Threadripper PRO 5975WX with 256GB of ECC DDR4. It will be years before I even attempt to mess with DDR5 again. Not impressed.
Good decision. Especially with the ECC rams. You will have an amazingly stable workstation. The only thing I don’t like about Threadripper builds is the lack of nice mainboards. I found most of them not really looking good.
same with amd ... got 7900x and 16x4 ddr5 6000mhz ram sticks .... only able to run ram @3600 mhz with timings 40 40 76 properly ... 3600+ and pc starts crashing and boot slow downs takes upto 70+ seconds sometimes to boot to windows !! what a waste of money
@@moriyokiri3229 I saw Corsair made 48GB memory modules available recently, not sure if they're compatible with AM5 now but they enable 96GB or 192GB memory total, maybe something to look into!
Wow, at least those of us who tried without knowing all the problems have the consolation of not being alone. Thank you. I tried everything to stabilize Windows 11 running 128GB without XMP on a z790 board. Ok for a few hours, then freeze, freeze, freeze at stock speeds. Latest BIOS. Wasn't a problem with CPU or paste or cooling, just this issue you were talking about four months ago! Cheers!
I chatted with Asus tech support and the rep said they are working on a BIOS update to address the XMP issue. I asked if I purchase 128 GB of RAM (x4 32GBs) from the QVL that a BIOS update (to come) would resolve the issue and he said it is in the works. He recommended 5600 or 5800 speeds.
To be fair, on Intel Ark product specification: i9-12900K : Up to DDR5 4800 MT/s i9-13900K : Up to DDR5 5600 MT/s Which leads me to believe that if you have a 13th gen, you can could run 5200 MT/s or even 5600 MT/s. Chip is out thursday officially. On vas bien voir!
Don't forget to read all the specs. 'Up to' 5600 mt/s on 13th gen. That's with 1 dimm per channel. I can't seem to find the damn chart unfortunately, however speeds decrease with increased ram. As in more sticks. Then you have the stress of single vs dual rank ram, dual rank puts more stress on the memory controller. Having all 4 dimms populated 2dpc, also adds more stress. And if you're talking ddr5, then a typical 32gb of ram in 2x16gb is just fine. It's 1dpc and single rank, there are no dual rank ddr5 at 16gb per stick. 32gb sticks and up are dual rank. Tech Notice here is using 4 sticks, 128gb so 32gb per stick. Worst case scenario, dual rank and 2dpc. The most stress on the memory controller. And of course intel's official speeds drop the more stress you add to the system. Hence the 'up to'. Then there's also the consideration that intel's officially supported speeds don't mean people 'can't' run faster ram, just that it's not guaranteed to run. You run a ddr5 1dpc setup of 2x16gb on 13th gen and you get ddr5 6000 it'll probably work. But if it doesn't, if for some strange reason someone got a low end lottery cpu and it will only function at 5600 mt/s, well that's all intel said it would run. They never promised more. There's no rma for that. I imagine if the chip was severely hosed and could only run 5200 mt/s within intel's specs, the cpu could likely be seen as 'faulty' and rma'd. Intel's already been confirming 13th gen working with ddr5 over 7000 mt/s so maybe they'll update their specs? But then they'd have to guarantee all 13th gen will handle it and that might be another story.
@@Mehecanogeesir Intel official specs aren't the 'max', just the confirmed spec. Many people enable xmp and get well over the 'max' on the intel specs but it's not guaranteed. Xmp is never guaranteed. The ram company can promise you 'ddr5 6400'. The motherboard can promise you 'max memory speeds of 7200+!'. But neither gets to dictate what you get. They can only speak for their component. That stick of ram 'can' run that fast, that motherboard 'can' run ram that fast. Ultimately it's up to the integrated memory controller in the cpu. In this case, intel. Some people could run ddr4 4000, others ddr4 3600. Some people put ddr4 3600 in their system and no boot with xmp enabled. It didn't like it. They had to drop to ddr4 3200 which was still technically more than intel promised for ddr4. But it wasn't what they were hoping for and what they were hoping for was a roll of the dice. Silicon lottery, like a good overclocker vs a poor one. The cpu's are all within manufacturing tolerance, a range of performance. Which is why you could have one cpu with a 'max' top end of 3.9ghz at 1.26v running 4.6 or 4.7ghz oc'd. And another with the same model cpu couldn't get 4.4ghz stable even pushing 1.3v core voltage. They had to settle for 4.2 or 4.3ghz. The reference to 'golden' chips meaning those in the same product line that were just the best tolerances and like a lucky lotto winner got a better version of the same thing out of the box.
I would love to see you give this a second try with a 13900k instead of the 12900ks (keep the same MB). It would tell us if the problem is in the chipset or the CPU. I think people invested in Z690 will not want to buy a Z790 so you would be answering if a new CPU could allow faster RAM speeds.
I'm running a 13900k and a ROG Maximus z690 Formula. I tried running two kits of CORSAIR Vengeance 64GB (2 x 32GB) @ 5200. I can enable XMP but the system was entirely unstable with BSOD after 15-30 minutes of running, as well as the system taking minutes to POST occasionally. I haven't tried manually setting the profile to try and get both kits running together. I can't be bothered putting in that much effort for it. Just gonna hope some people smarter than me resolve it in an easy manner.
I watched all your videos on DDR5 issues as I came across an issue on my own system. I am running an Asus z690e wifi + I9 12900k + 4 sticks of 16GB T-force ram rated for 6400Mhz. I originally built my PC with 32GB but then amazon had a sale on the same ram, so I added another 2 sticks to make it 64gb all together. Upon adding the 2 new sticks, BSOD started happening. What worked for me was bumping up the voltage from 1.35 to 1.37 and changing ram power deliver system from " synced all 4 " to "per dimm" and reducing my clock speeds from 6400 to 6200 . So far I was able to get stable sessions from my pc and I hope it stays this way ....
Your conclusion is on point. You want to build your PC then use it. Not tune the parts because of glitches from the manufacturer's end. GREAT POINT. This philosophy should be applied to CPUs and GPUs as well unless you're an enthusiast.
This guy was really helpful for building a new pc, I had my Asus rog mobo, Corsair DDR5 ram (6000mhz) x 4 stick and intel i9 13900k, 13 gen, turn on XMP, and voila no boot. I even update the mobo BIOS and driver on Windows 11 with no luck. I haven’t tried to take out 2 rams yet, but I am pretty sure this will solve my issue. So anyone who wants to buy 4 sticks, do some research first since overclocking is still not stable with gen 12/13th mobo, unless you are confident with changing Voltages for CPU or memory. Good job mate.
Thanks for answering why there's no 4 sticks available for DDR5 ram. Creators are going to drag their feet even more in adopting next gen with such a problematic hardware bottleneck.
Yeah DDR5 is still bleeding edge, it's part of the reason why I got a DDR4 board for my build, it's much easier to get high capacity of RAM. I don't think DDR5 will really be worth adopting for about another year.
not using 4 sticks but when using 2 sticks of kingston Fury 5600, the XMP did go into windows, done benchmarks right, only once a while crash in MSFS, and don't pass FFT512+ prime 95 over 2 hours at XMP, perfectly fine with 4800MT, ended up the solution, was disabling the dynamic memory boost, now rock solid in prime 95 with XMP
This finally answers the questions concerning "Plug and Play," which has often been called "Plug and Pray." I've been building PCs since the late 1980s; remember MS-DOS and early individual memory chips? None of this is new to me. Problems like this are just a part of building a PC. Sometimes you must learn to live with it or go crazy. Don't worry; just let someone else figure it all out. Hot running DRAM? You can purchase small fan DRAM coolers to solve that.
So many people reported this type of issue on AM5 and 12/13th gen intel. I plan on buying 2x32GB kit for my next build with Zen 5 or 14th gen intel for now until the situation improves with both ram channels populated. Also if you're a scientist, engineer, or creator you really just need rock-solid stability. Even as an enthusiast I am leaning toward running my next rig at stock settings because AMD is pushing their chips to the limit out of the box. Less than 5% of performance uplift on them isn't worth the instability. With Intel, at least for now you still get gains overclocking but at the cost of a ton of power and cooling increases.
Yeah, this explains a lot. I've got 4 sticks of 16GB 6400 MHz Kingston Fury w/ intel 13900k, can't run XMP at all, even at the slowest 4800 MHz profile. Blue screens everywhere. Forced to run stock @4000 MHz. Sucks from a consumers perspective that these chips are advertised at the higher speeds when they're unable to run at that frequency.
Still can’t do it with an MSI Z790-P and 14700K. I’m gonna prolly return the 2x16 sticks I got cuz I couldn’t get all 4 to run at CL 40 6000MT/s. 4000MT/s was the only stable speed.
I got 4*16 DDR5 6000MT CL40...with XMP the PC boot but lots of errors in MEMTEST...I lowered the MT to 5200 and CL to 28-34-34-68 1.350v...and works like a charm no errors 😁
You might need to look at the memory support of your board. 4x16GB might be 1R, (heard it could sometimes be 2R which further lowers the potential clock speeds you can reach) and 2DPC 1R could be rated to well under 6000MHz. The board I got for the 2 sticks of 32GB I got is rated for "1DPC 2R Up to 6000+ MHz" so my 5600MHZ should have a high chance of just working fine. If I got another pair It most likely wont run above 4800 as it's only rated for "2DPC 2R Up to 4800+ MHz" which is what 4x32GB sticks function as.
@@JoshM7 2 STICKS of ram can run @6400MT on my board ...But now after the latest BIOS , I can run 4 sticks @5600MT and 28-30-30-60 1.350V without any errors in memtest
13:32 It would have booted anyway. I'm not sure if you tried because of editing and not live, but I just put 6000 in my 12700K rig, and it did that same thing down to the letter. But when it said it was reset and you pulled that channel of RAM, I did not. Instead, I went into BIOS and turned on XMP (6000), rebooted like normal, and it worked like a charm. Has been running solid ever since. Not sure what that corruption message was, but all it did was reset the BIOS back to the factory, and then I just turned on XMP, and that was it.
Thanks; just updated my 2x32GB Kingston Fury Beast RGB DDR5-5200 with an extra set on Asus Z690-Plus with i9-12900KF CPU; did not work with the advertised 5200 Mhz. Troubleshooting and found your channel. Already running latest and greatest BIOS. Will keep an eye out here - thank you for the detailed video.
Your videos have been very helpful and informative! Yes, G. Skill DDR 5 5600 kept getting BSODs (I thought a DIMM slot was bad) running on ProArt Z690 Creator Wifi mobo with i9-12900K, new build Bios 2004 & GeForce RTX 3090..however, runs great on 2 sticks at 5600. I don't want to have to continually do tweaks to run 4 sticks. Thank you for your update!
Nope mine would not write correctly with nearly 4000 errors with 4 sticks in system. Wish I would have know this before buying 4 sticks of DDR5 memory. Memory test sent: sent RRWWGET but read RRWWDET errors out the ying yang. 2 sticks of 7200 runs the memory test great, no issues.
its still early adopter of ddr5, but the headaches and the pricing is why i went ddr4. i belive mr tech notice also mentioned for creation amount is greater than speed. i might be wrong.
You’re not doing the correct settings in the BIOS. After you set the XMP profile the next step is to go down to DRAM VDD Voltage and set it the voltage to 1.3. Then change DRAM VDDQ Voltage to 1.3. THE FINAL STEP!!! Go to “AI Tweaker Advance Memory Voltages and go down to PMIC Voltages and change it to “By Per PMIC” save and exit. Restart, it may take some time, and then it will work.
Hey! so ive got a 12900k, 64GB DDR5 6400Mhz, Z690 Aorus Master MB, 3080 ti aorus master and this crashes on their own xmp profile i cant even boot and i get a memory code on the motherboard all my games stutter when im streaming in 1080p and playing in 4k max on apex and this is kind of ridiculous because i bought almost the best everything and nothing is working right in either windows 10 or 11
Aesthetics are important to me next to performance. Obviously performance first. That being said I wish Corsair would continue making the fake dimms for DDR5 with all its RGB kits. Vengeance and Doms. A mobo with 2 slots being used out of 4 just doesn’t look good when using RGB ram.
People spend too much time obsessing over the innards of their pc when concerning "keeping up with the Joneses". I remember a time when people just played games without caring so much about what brands were under the hood.
Advertised speeds are for the memory it doesn't guarantee that the mem mb and proc combo can reach that speed. Hint: look at the intel specs for its processor mem speed.
I was replacing 2 corsair 3200mhz 8g sticks,and had to boot the PC without ram before I even put in the 4 sticks of trident z 3600mhz. If you are upgrading dump the memory first it makes it easier and the PC will default and dump old configuration.Or if you are replacing ram in A2 and B2 ,take them out and ut the new sticks in A1 and B1 and then it will work since those slots are open.I thought you only did that with AM3+ I guess it works for Am4+.My friend works at asrock he told me that secret.Because clearing bios with ram still in the PC aint going to reset those slots to default it holds those settings till it boots.
i got 4 DIMMs at EXPO to work, i run 4 Gskill Flare x5 5600 on a Asrock X670e Pro Rs , & i actually am using their first initial bios with the motherboard (1.03) & my OC is stable, when i update my bios to their recent versions (1.07) i cant get it to post, took me a day of testing to figure this out
Fantastic video, thank you. I am having the exact same issues with my new computer. Just bought the Corsair Vengeance i8100 that came with 2 sticks of 32Gb Dominator DDR5 ram clocked at 6,000MHz. Tried installing 2 more 32 Gb sticks of the exact same ram. Same speed, size same everything and the new computer would not go more than 3 min. without a crash and need to reboot. I even got 2 blue screens and total system lock up in the first hour. When I pulled the new ram back out, everything started working great. Also, when I removed the added RAM, it was very hot to the touch. About to watch your update video. Hope it has a solution to the problem.
I had no issues until today when booting up my system it simply didn’t power up! I removed the memory (G.Skill 4 16GB) sticks on my Asus Prime Z690-A Mobo and the CMOS battery. I installed them back after 5 minutes and the BIOS screen popped up, made adjustments mentioned above (XMP 1) and saved it and still an issue. The only way it will boot up properly to windows is by removing the memory sticks but one. I didn’t have this issue before and it ran beautifully with 64GB of ram until today.
This isn't limited to DDR5, or Intel, XMP always was dodgy with more than 2 sticks... It's a synchronization issue... Sometimes you can get around it by shuffling the sticks around, sometimes you can relax the timings manually, sometimes you can lower the frequency by 100-200MHz and then it works fine. Try your XMP 6000 setting, but manually set the clock to 5800 MHz instead.
Indeed, I am having the same issue with 4x32GB in an AM4 B550 board with BIOS from August 2023. Runs at 2133, won't post at 3200 (the one XMP profile). I haven't tried anything in between yet. The RAM is Corsair CMK64GX4M2E3200C16. If you dig, 2133 appears to be the highest frequency at which it is guaranteed to run. It's a scam. They advertise the memory as 3200, include that number in the article number and what it actually means is "if you have no more than two DIMMs, of not too high capacity/density, with a bit of luck you may be able to overclock it to 3200 MHz and make it to a desktop without crashing".
AMD 7950x here with 128GB (4x32) G.Skill Flare X5 on ASRock x670e, I can occasionally boot with AMD EXPO for my ram but have experienced memory corruption (confirmed with memtest) so I disabled it. The extra speed would be nice but the capacity is essential for me.
Depends on the bios. Some versions of bios wont allow it properly due to new updates for newer cpus for the MB. I found with mine, i had to manually set the ddr voktage up .2 volts when using XMP. Older bios, xmp will work without voltage change. Something to do with bios uogrades and cpu compatibilities.
from what i have heard lately, it is about how 32GB+ sticks are DUAL channels which max out the bandwidth. anything else "overloads" it and really doesnt make much of a difference. i am completely new to the DDR5 quirks but it makes sense. i found that corsair currently sells a 4 stick kit BUT its only 8GB or 16GB but they are only single channel sticks. from how it was explained in a video, a single channel is writing or read only. dual channel can read and write at the same time. there seems to only be 4 channels for a 4 DIMM mobo. the only way that a lay man like me can think of is that mobo will have to have 8 channels for 4 DIMMs. however, i think that would impact the cpu and mobo development quite a bit. hope this might make a little sense. PS- single channel, the ram chips are on ONE side of the stick. dual channel has ram chips on BOTH sides.
On my AMD 7950 running 4 sticks of ram at 5600 MT/S my system bullet stable at this specs but with 4 stick of ram 64 GB total 6000 Mhz NOT STABLE the system boots up but not stable tested with Memtes 86+ , AIDA 64 Stability test , OCCT Test Not stable I tried every method not stable at all none of them worked for 4 sticks of ram !

Currently running a z690 with 128 gigs at 6k mhz. I have a LOT of instability. Iv had days where I tune it and it runs great all day all 4 sticks but usually on restart or idle it crashes and goes into boot loops. Upping voltage helped, I’m going to try a few different things but this process is lengthy
I bought my X570 PC before I was aware of the limitations with regard to populating all memory slots. I should have bought 2 16gb sticks. The memory controller has a tough time with maintaining a 1 to 1 "Infinity Fabric" (1,800Mhz) with all memory slots populated. 16gb sticks were somewhat rare and expensive at the time. I bought 4 sticks of 3,600Mhz c14, 15, 15, 15, 35 (Samsung B-die), and though I could get all 4 sticks to operate at their XMP profile, I had WHEA errors. They were incredibly intermittent- sometimes going for days without a reboot even though correctable WHEA errors were happening in the background all the time. This lasted through several different video cards, and 2 CPU's- as I had a 5600x prior to the 5900x. Recently, I bought a new GPU, and while changing it my water pump died. While replacing the water pump, and the GPU, I accidentally ripped the 5900X out of its socket without releasing the bar- ouch. This happened because of how damn well the Thermal Grizzly pink thermal paste was adhering between the CPU, and waterblock. While simply trying to remove the water block, it pulled off the CPU with it. However, there was no damage, it just cleaned the pins, even scraping off a thin layer of gold plating(I wonder where that went). I crossed my fingers and reinstalled everything, and thankfully it posted, and booted just fine, and low and behold- no more WHEA errors.. It's been almost two weeks, now. What the hell? Was one of my pins dirty, and not getting good contact?! Now I'm afraid to change anything.
For some reason, I couldn’t change anything in my Gigabyte Bios. But after I unplugged the battery for 20 seconds, with no power cable and turned on my PC with all 4 Ram blocks. It worked perfectly 🙂
Just built a system with 128GB DDR5 based on 6600 sticks. Can boot Win11 at 5400. Knew I have to sacrifice clock rate with 4 sticks. Finally can be stable at 4800 with aggressive latency parameters (tCL-tRCD-tRP-tRAS etc.). On the future upgrade path from 64GB two stick, I'm unsure if I can get the exactly same 64GB sticks later. So might as well get 4 sticks now or none.
I got a 7800X3D. I went with 4 sticks of T-Create 6000MTs CL30. I get weekly blue screens. Surprisingly stable since it's only weekly. I can work hardcore creator workloads for entire days straight with no issues, but once a week I'll be randomly hit by a blue screen. I've ruled out every other possible cause, and none of the RAM sticks are bad. This is my first time going with 4 sticks and now I wish I went with 2 lol, but I am experimenting now with trying to get it fully stable since it's been surprisingly stable otherwise. I've rolled by speeds to 5600MTs to keep the timings, since AMD seems to respond better to low timings; as opposed to higher speeds. If that doesn't work I'll try 5200MTs at CL30. If that doesn't work maybe I'll try CL34; basically copying the 2x32 spec from teamgroup. If that doesn't work I'll try 5600MT at CL40, or take half the sticks out and call it another learning mistake in PC building lol...like when I built my first & only dual-GPU PC in 2012.
I actually bought 4 sticks of that exact Kingston Fury DDR5 RAM up to 128 GB but haven’t built it into a system yet. Are you saying that without XMP (at base speed) it will be stable but it just can’t be overclocked? If so, that’s not the biggest deal for me since my workflow just requires the capacity to hold lots of music samples. I wasn’t planning to overclock. Are the sticks stable without XMP?
I think we need to see you build the ASUS Z790 Creator mobo, with the I9-13900k CPU and test 128gb DDR5 with that. If it works that's what I'm buying!! 😀
I agree keeping the BIOS up to date is important. It can sometimes have a bad effect if a system is already stable but on new/cutting edge tech it often solves more issues than it causes. As a tip: I found a need on my ASUS boards to also do a clear CMOS and reset to default settings before reconfiguring all the settings again as this had a material impact on performance and stability. Reloading saved profiles or not loading back to defaults would sometimes see strange behaviour.
When you update the bios tbe saved profiles are removed and a cmos is done automatically for you. I learned the hard way and lost all my configs / oc undervolt but figured it back out 😂 and took screenshots of my uief settings
Agree, it wipes the saved profiles when doing an update. I loaded my saved profile from a USB drive I had exported it to assuming it would be fine and found it wasn’t 100%. Reconfiguring the exact same settings after a Clear CMOS manually resulted in a much better stability and slightly more performance.
I was looking for 4 x 16GB or 4 x 32GB kits and there's literally nothing. That the motherboards are advertised as 128GB capable with RAM kits on QVL is hugely misleading if not downright false advertising. How does one get 128GB @ 6,000mhz DDR5 today? You can't. Interesting video!!

i agreed with all your comment, 4x DIMM won't work stable for long .. although you have pass all memory test doesn't mean you can pass with your daily work. for my case, i had to left it with 2x DIMM and set myself limit
I'd love to take the plastic off my ram sticks, and put some all metal heatsinks with optimized topology for moving air, and then just slap a 4 slot ram cooler on top. I bet we could really push the limits then.

Thanks for the in-depth video. I got a Ryzen 7590x setup myself with 2 sets of 2x32GB kits. Even at the stock bios speeds it was very unstable, and I ended up returning my first motherboard because of it. Having the same issue on the next board, I ended up having to de-clock and up the voltage on the RAM manually to get it stable. So far I have 4200MHz at CL32 stable. Far from the advertised 5800MHz on the sticks. I do hope this is all fixable with future updates, and not hardware limitations.
@@ChatGTA345 with the latest bios update, I've been able to get 4800 cl 36 stable, but I had to increase the voltages and go up to 1.4v to the sticks.

I was able to get 4 chips to work on my pc a little more stable by going into AI Tweaker\Advanced Memory Voltages and under PMIC Voltage, you select By per PMIC
Crucial uses micron for their ram, which is more stable than Samsung or Hynix. But cannot be pushed into higher speeds like them so you are unlikely to see anything above 5600mhz from them for now. So they can have a higher jdec spec than 4000.
As far i remember from the 12th gen cpu reviews, tt's not a matter of ram or either motherboards. It's the cpu that doesn't support 4 stick of memory in xmp mode
i saw similar issue earlier on other video called "Be Careful Before Buying Intel 12th Generation Memory(i might be wrong)" on a JayzTwoCents channel, he also tried to boot with 4 sticks at full speed and motherboard failed that. Also i read some "theory" in discussions about that, and it seems caused by low count of PCB layers/trackways. Actual/current boards only have about 8+ layers(i might be wrong), so there a required more "thicker" boards with more layers/trackways, and i hope that will become with 700-chipsets. That's why i decided to skip DDR5 on the 600-chipsets until 700 come out, and save some money by pairing 12700k with DDR4 board and RAM that i already have.
I bought a new build with a Tuf z790 plus wifi motherboard, I7 13700k cpu, Gigabyte RTX 4080 OC and a 2x16 32gb Corsair Dominator 6200mhz ddr5 kit. Every time I tried to enable the XMP profile the system would fail post. I found a forum thread that mentioned slot population, I removed the dimms and populated the 2 dimms in slots 2 and 4, BANG! XMP working at 6200mhz, no issues at all.
@@n4ul17o yes but apparently thats just DDR5, not sure if correct but the way I understand it is that it needs the extra latency because of how fast it is.
Be warned if you update your bios you lose your old bios settings. So record your settings before updating! Also just buy larger 2x capacity sticks. Also if you buy a k series cpu then you fine tune that so there's no reason not to fine tune your ram. Try loosening the timings (if it won't boot) the last tip I'll give is don't buy dd5 in the 1st place 🤣🤣
Hey i just installeed 32 more gb ram into my rig with 4 sticks instead of 2 Had no issue with xmp on 32 gb but after getting new ram my pc restart alot. What Can i do?
I got stable working by manually lowering profile at AI tweaker at BIOS (asus z790e), standart 6800mhz, I reduct it to 6200mhz with XMP turned on and everything work properly (G.Skill 6800mhz, 4x16gb)
Even after all this time , ram, cpu and boards manufacturers really need to solve this with 4 sticks!!! 4 sticks! 128 Gig still will not run at 5000 or 6000 very disappointing
Ditto. I hope we can get that tested when the 13th gen and Z790 come out next week. Anyone know if there's been any announcements for release dates for 64GB DDR5 sticks?
Buy your memory based on your own requirements (i.e. understand your workloads). If you need capacity (especially the max supported by the platform) you will not get JEDEC defined standard speeds. If your workloads are latency sensitive you should target a single stick per memory channel. Ranks might also play a role here, but it will depend on platform. Each generation of CPUs will come with improved memory controllers. Intel 12th gen can do 4800, AMD 7000 series can do 5200, rumors suggests that Intel 13th gen could do 5600. This will probably slowly go towards 7200 (but will take years).
Hello. Do you think the DDR5 would make a big difference in comparison with DDR4 using i7 13th g. and Z790 motherboard for music and video production? Worth it?
This is a nightmare. I was running 2x32Gb for some months, running perfectly at 6000Mhz. And now i saved some extra money and got 2 other identical blades. Vengeance 32x2 (64Gb) CL32-6400Mhz. Updated my Msi Bios to latest (It's a AM5 system) 7950x. The full Ram (128Gb) identified at bios, but after the first boot, never POST again. So i had to PHYSICALLY remove 2 blades to be able to see the Bios again, down the speed to 4000Ghz and now they finally Boot. Also the Boot is Soooooo SLOW takes ages to start loading windows. When it start loading it it loads fast.
Ive got b660m pro rs 12400f with 2 sticks RAM corsair vengeance rs 3200gb 8x2, i'm about to upgrade 2 more sticks and also can i turn xmp with 4 sticks?
Thanks so much for this video. I had given up on enabling XMP with my 4x16gb 5200mhz DDR kingston fury ram. I have a msi z690-a pro with a 12700k cpu and updating the bios finally posted. I haven't run any benchmarks but it posts and does everyday tasks just fine.
love the info on ram!b With so many brands out there it is so easy to over spend! All this info is helping me see how much I need, what speeds and what I don't need! Thank you!
Here is my janky solution. Using corsair 6000 mt/s RAM 32 gb, 2 sticks on a TUF z790 PLUS WIFI board. XMP doesn't want to boot? If you're using corsair RAM, make sure ICue is installed (the software that controls corsair products such as RGB lighting and for some reason, RAM). Then go into bios, turn off xmp in easy mode, then go to the AI tweaker in the advanced settings and manually set the DRAM frequency to whatever your kit allows. Don't change anything else. For me this has led to the RAM working perfectly with every setting left on automatic.
The 4x DDR5 RAM problem of the Asus Prime Z690-A was solved with Bios update 2305. Have all my G Skill Tridenz Z5 5600Mhz installed & tested with MemTest86 V10.2 free (USB). Before it was not possible for me 4x DDR 5 with 5600Mhz stable to run. am glad that it now runs. Great video THANKS
I'm running the ProArt Z690 board with latest BIOS 2305 and 4 sticks of G Skill Trident Z5 5600Mhz with timings of 30-36-36-89 with no luck. I can get it to *almost* pass memtest with it running at 5000 40-40-40-79 but there's always one or two memory errors that show up. Still doing various tests to see if I can make it stable at all.
@@seephor I own 2x the following set: G.Skill TridentZ Z5 RGB 32GB DDR5 5600, CL28, (2x16GB), F5-5600J2834F16GX2-TZ5RK. Works on my Asus Prime Z690 without problems. Whether the RAM in the XMP (all over 4800mhz is oc) works with your CPU is of course dependent on the CPU, not just the RAM.
the problems you had with 4 sticks i had with 2 sticks of kingston fury beast on an asrock 790 pro rs . I was getting black screen with 2 dimms on. At least it was showing bios with 1 stick So i put lesser values and then it worked with 2 sticks in dual channel. But i had to drop it from 6000 to 4800 and up latencies to 42

i got a question, if i got 2x16 sticks of corsair vengeance ddr5 5600mhz cl36 and another 2 same but 32x2, can i use 4 of them together? or in order to the pc dual chanel to work properly it has also to have same capacity ? and if can i use them together, can i use xmp for 4 of them together?
I have the same specs as you have, the exact same Kingston Ram, even the same GPU. I only have a different CPU, an AMD Ryzen 9, 7900x cpu running on an ASUS Prime B650-Plus. According to specs this board also supports that ram, according to the QVL. I have not been messing in the bios at first. Tried 64GB, ran perfectly fine at 4,800Mt/s. Then added the other two dimms for the total of 128GB, but my pc wouldn't boot. I tried turning on Memory Training, but I simply could not get into the bios. Only when removing two dimms it worked again. For me it's not even needed 4 dimms running at 4,800Mt/s. If all of them ran at 3,600Mt/s it would be fine as well, but also this combination is not working. And, I did upgraded the bios a few days ago. It could probably be the motherboard, which is not the most expensive board, but one could assume if the specs say, it can handle 128GB, it should be able to handle 128GB. So currently I have 2 (expensive) Kingston dimms lying here collecting dust. Any suggestion how I get 4 of them working? 128GB on 3,600Mt/s is faster than 64GB on 4,800Mt/s. It did work for a while, but I noticed after the bios update (when all settings are reset, and of course the 4 dimms were set back to auto, the pc refused to boot again), that after removing the 2 extra sticks my video editor is working a lot slower. I do a lot of video effects, encoding on 4K video material. Any suggestions on how to get this working?
Do you plan to test the crucial 128Gb, which have default speed @4800? It's also listed at the Pugets recommended system for Davinci resolve. Thank you for all the info, keep up the excellent work!
tried running 4x 16GB @ 7200 on 13900K ... it will boot. But as soon as any serious load on the system it will crash. I think I will try to bump it down to 6800 or 7000MHz. It seems like it's almost there. It runs perfectly fine @ 7200 MHz with 2 sticks.
Here's an update/explanation to this video: th-cam.com/video/wzVZgTP2204/w-d-xo.html
I have AMD build same problem with the Asus Tuf X670E motherboard first dual (kingstom ram 2×16) channel works on 6000mhz. But if use 4 dual channel it not boot up to windows. Strange things is you can see and hear fans spinning plus all ram have rbg light up but black screen. So issue is not the ram stick but need a firmware update ???
I built a 12900KS with the ProArt Z690 and 128GB of DDR5. As you highlighted in this video, I had continuous issues trying to get the sticks to operate at anything above base clock. The system would refuse to POST and usually required me to remove the other two sticks of RAM before it would even boot again. Every time a new BIOS version was released for that board. I immediately installed it, hoping it would correct the issues, but it never did, to include the very latest version with 13th Gen support. I dropped everything on eBay and built a Threadripper PRO 5975WX with 256GB of ECC DDR4. It will be years before I even attempt to mess with DDR5 again. Not impressed.
Good decision. Especially with the ECC rams. You will have an amazingly stable workstation. The only thing I don’t like about Threadripper builds is the lack of nice mainboards. I found most of them not really looking good.
@Ms Moon Boo done mate. I was a little too fast. sorry for that :-)
@Ms Moon Boo I also deleted the other comment.
why are you so rich?
i mean..... the reason is due to ddr5 using 4 seperate channels on 2 sticks.. 4 sticks = 8octo if single sided.
Thank you for being one of only a few TH-camrs to talk about this issue. If feel like creators have been left out by the manufacturers for this gen 😕
same with amd ... got 7900x and 16x4 ddr5 6000mhz ram sticks .... only able to run ram @3600 mhz with timings 40 40 76 properly ... 3600+ and pc starts crashing and boot slow downs takes upto 70+ seconds sometimes to boot to windows !! what a waste of money
The clock speed of the ram is memory controller/ motherboard dependant. 2 will always clock faster than 4 though. On a like for like comparison.
i'm crying something please think of the "creators"
@@moriyokiri3229 I saw Corsair made 48GB memory modules available recently, not sure if they're compatible with AM5 now but they enable 96GB or 192GB memory total, maybe something to look into!
Wow, at least those of us who tried without knowing all the problems have the consolation of not being alone. Thank you. I tried everything to stabilize Windows 11 running 128GB without XMP on a z790 board. Ok for a few hours, then freeze, freeze, freeze at stock speeds. Latest BIOS. Wasn't a problem with CPU or paste or cooling, just this issue you were talking about four months ago! Cheers!
It's the imc of the CPU, most likely :)

OMG. I was WAITING for someone to mention this! Am so glad that you did.
I chatted with Asus tech support and the rep said they are working on a BIOS update to address the XMP issue. I asked if I purchase 128 GB of RAM (x4 32GBs) from the QVL that a BIOS update (to come) would resolve the issue and he said it is in the works. He recommended 5600 or 5800 speeds.
To be fair, on Intel Ark product specification:
i9-12900K : Up to DDR5 4800 MT/s
i9-13900K : Up to DDR5 5600 MT/s
Which leads me to believe that if you have a 13th gen, you can could run 5200 MT/s or even 5600 MT/s. Chip is out thursday officially. On vas bien voir!
ur right, i just got an i9 13thgen , and my ram finally runs at 5600mhz 64gb without any problem
@@rekenops8651 Four sticks?
So how are people getting their systems to work with higher clocks?
Don't forget to read all the specs. 'Up to' 5600 mt/s on 13th gen. That's with 1 dimm per channel. I can't seem to find the damn chart unfortunately, however speeds decrease with increased ram. As in more sticks. Then you have the stress of single vs dual rank ram, dual rank puts more stress on the memory controller. Having all 4 dimms populated 2dpc, also adds more stress. And if you're talking ddr5, then a typical 32gb of ram in 2x16gb is just fine. It's 1dpc and single rank, there are no dual rank ddr5 at 16gb per stick. 32gb sticks and up are dual rank. Tech Notice here is using 4 sticks, 128gb so 32gb per stick. Worst case scenario, dual rank and 2dpc. The most stress on the memory controller.
And of course intel's official speeds drop the more stress you add to the system. Hence the 'up to'. Then there's also the consideration that intel's officially supported speeds don't mean people 'can't' run faster ram, just that it's not guaranteed to run. You run a ddr5 1dpc setup of 2x16gb on 13th gen and you get ddr5 6000 it'll probably work. But if it doesn't, if for some strange reason someone got a low end lottery cpu and it will only function at 5600 mt/s, well that's all intel said it would run. They never promised more. There's no rma for that. I imagine if the chip was severely hosed and could only run 5200 mt/s within intel's specs, the cpu could likely be seen as 'faulty' and rma'd. Intel's already been confirming 13th gen working with ddr5 over 7000 mt/s so maybe they'll update their specs? But then they'd have to guarantee all 13th gen will handle it and that might be another story.
@@Mehecanogeesir Intel official specs aren't the 'max', just the confirmed spec. Many people enable xmp and get well over the 'max' on the intel specs but it's not guaranteed. Xmp is never guaranteed. The ram company can promise you 'ddr5 6400'. The motherboard can promise you 'max memory speeds of 7200+!'. But neither gets to dictate what you get. They can only speak for their component. That stick of ram 'can' run that fast, that motherboard 'can' run ram that fast. Ultimately it's up to the integrated memory controller in the cpu. In this case, intel. Some people could run ddr4 4000, others ddr4 3600. Some people put ddr4 3600 in their system and no boot with xmp enabled. It didn't like it. They had to drop to ddr4 3200 which was still technically more than intel promised for ddr4. But it wasn't what they were hoping for and what they were hoping for was a roll of the dice. Silicon lottery, like a good overclocker vs a poor one. The cpu's are all within manufacturing tolerance, a range of performance. Which is why you could have one cpu with a 'max' top end of 3.9ghz at 1.26v running 4.6 or 4.7ghz oc'd. And another with the same model cpu couldn't get 4.4ghz stable even pushing 1.3v core voltage. They had to settle for 4.2 or 4.3ghz. The reference to 'golden' chips meaning those in the same product line that were just the best tolerances and like a lucky lotto winner got a better version of the same thing out of the box.
I would love to see you give this a second try with a 13900k instead of the 12900ks (keep the same MB). It would tell us if the problem is in the chipset or the CPU.
I think people invested in Z690 will not want to buy a Z790 so you would be answering if a new CPU could allow faster RAM speeds.
13th gen + z790 still can't enable the xmp with 4 sticks
I'm running a 13900k and a ROG Maximus z690 Formula. I tried running two kits of CORSAIR Vengeance 64GB (2 x 32GB) @ 5200. I can enable XMP but the system was entirely unstable with BSOD after 15-30 minutes of running, as well as the system taking minutes to POST occasionally. I haven't tried manually setting the profile to try and get both kits running together. I can't be bothered putting in that much effort for it. Just gonna hope some people smarter than me resolve it in an easy manner.

I watched all your videos on DDR5 issues as I came across an issue on my own system. I am running an Asus z690e wifi + I9 12900k + 4 sticks of 16GB T-force ram rated for 6400Mhz. I originally built my PC with 32GB but then amazon had a sale on the same ram, so I added another 2 sticks to make it 64gb all together. Upon adding the 2 new sticks, BSOD started happening. What worked for me was bumping up the voltage from 1.35 to 1.37 and changing ram power deliver system from " synced all 4 " to "per dimm" and reducing my clock speeds from 6400 to 6200 . So far I was able to get stable sessions from my pc and I hope it stays this way ....
Your conclusion is on point. You want to build your PC then use it. Not tune the parts because of glitches from the manufacturer's end. GREAT POINT. This philosophy should be applied to CPUs and GPUs as well unless you're an enthusiast.
This guy was really helpful for building a new pc, I had my Asus rog mobo, Corsair DDR5 ram (6000mhz) x 4 stick and intel i9 13900k, 13 gen, turn on XMP, and voila no boot. I even update the mobo BIOS and driver on Windows 11 with no luck.
I haven’t tried to take out 2 rams yet, but I am pretty sure this will solve my issue. So anyone who wants to buy 4 sticks, do some research first since overclocking is still not stable with gen 12/13th mobo, unless you are confident with changing Voltages for CPU or memory. Good job mate.
Thanks for answering why there's no 4 sticks available for DDR5 ram. Creators are going to drag their feet even more in adopting next gen with such a problematic hardware bottleneck.
Yeah DDR5 is still bleeding edge, it's part of the reason why I got a DDR4 board for my build, it's much easier to get high capacity of RAM. I don't think DDR5 will really be worth adopting for about another year.

@@MistyKathrine There's an easy fix; It's go AMD.
not using 4 sticks but when using 2 sticks of kingston Fury 5600, the XMP did go into windows, done benchmarks right, only once a while crash in MSFS, and don't pass FFT512+ prime 95 over 2 hours at XMP, perfectly fine with 4800MT, ended up the solution, was disabling the dynamic memory boost, now rock solid in prime 95 with XMP
This finally answers the questions concerning "Plug and Play," which has often been called "Plug and Pray." I've been building PCs since the late 1980s; remember MS-DOS and early individual memory chips? None of this is new to me. Problems like this are just a part of building a PC. Sometimes you must learn to live with it or go crazy. Don't worry; just let someone else figure it all out. Hot running DRAM? You can purchase small fan DRAM coolers to solve that.
So many people reported this type of issue on AM5 and 12/13th gen intel. I plan on buying 2x32GB kit for my next build with Zen 5 or 14th gen intel for now until the situation improves with both ram channels populated.
Also if you're a scientist, engineer, or creator you really just need rock-solid stability. Even as an enthusiast I am leaning toward running my next rig at stock settings because AMD is pushing their chips to the limit out of the box. Less than 5% of performance uplift on them isn't worth the instability. With Intel, at least for now you still get gains overclocking but at the cost of a ton of power and cooling increases.
Yeah, this explains a lot. I've got 4 sticks of 16GB 6400 MHz Kingston Fury w/ intel 13900k, can't run XMP at all, even at the slowest 4800 MHz profile. Blue screens everywhere. Forced to run stock @4000 MHz. Sucks from a consumers perspective that these chips are advertised at the higher speeds when they're unable to run at that frequency.
Still can’t do it with an MSI Z790-P and 14700K. I’m gonna prolly return the 2x16 sticks I got cuz I couldn’t get all 4 to run at CL 40 6000MT/s. 4000MT/s was the only stable speed.
Is this still an issue with the 13th Gen CPUs??

@@EvenHarmonics Corsair Vengeance RGB DDR5 6000MT CL40
You might need to look at the memory support of your board. 4x16GB might be 1R, (heard it could sometimes be 2R which further lowers the potential clock speeds you can reach) and 2DPC 1R could be rated to well under 6000MHz.
The board I got for the 2 sticks of 32GB I got is rated for "1DPC 2R Up to 6000+ MHz" so my 5600MHZ should have a high chance of just working fine. If I got another pair It most likely wont run above 4800 as it's only rated for "2DPC 2R Up to 4800+ MHz" which is what 4x32GB sticks function as.

13:32 It would have booted anyway. I'm not sure if you tried because of editing and not live, but I just put 6000 in my 12700K rig, and it did that same thing down to the letter. But when it said it was reset and you pulled that channel of RAM, I did not. Instead, I went into BIOS and turned on XMP (6000), rebooted like normal, and it worked like a charm. Has been running solid ever since. Not sure what that corruption message was, but all it did was reset the BIOS back to the factory, and then I just turned on XMP, and that was it.

You’re not doing the correct settings in the BIOS. After you set the XMP profile the next step is to go down to DRAM VDD Voltage and set it the voltage to 1.3. Then change DRAM VDDQ Voltage to 1.3. THE FINAL STEP!!! Go to “AI Tweaker Advance Memory Voltages and go down to PMIC Voltages and change it to “By Per PMIC” save and exit. Restart, it may take some time, and then it will work.

Aesthetics are important to me next to performance. Obviously performance first. That being said I wish Corsair would continue making the fake dimms for DDR5 with all its RGB kits. Vengeance and Doms. A mobo with 2 slots being used out of 4 just doesn’t look good when using RGB ram.

If you are upgrading dump the memory first it makes it easier and the PC will default and dump old configuration.Or if you are replacing ram in A2 and B2 ,take them out and ut the new sticks in A1 and B1 and then it will work since those slots are open.I thought you only did that with AM3+ I guess it works for Am4+.My friend works at asrock he told me that secret.Because clearing bios with ram still in the PC aint going to reset those slots to default it holds those settings till it boots.
i got 4 DIMMs at EXPO to work, i run 4 Gskill Flare x5 5600 on a Asrock X670e Pro Rs , & i actually am using their first initial bios with the motherboard (1.03) & my OC is stable, when i update my bios to their recent versions (1.07) i cant get it to post, took me a day of testing to figure this out
Fantastic video, thank you. I am having the exact same issues with my new computer. Just bought the Corsair Vengeance i8100 that came with 2 sticks of 32Gb Dominator DDR5 ram clocked at 6,000MHz. Tried installing 2 more 32 Gb sticks of the exact same ram. Same speed, size same everything and the new computer would not go more than 3 min. without a crash and need to reboot. I even got 2 blue screens and total system lock up in the first hour. When I pulled the new ram back out, everything started working great. Also, when I removed the added RAM, it was very hot to the touch. About to watch your update video. Hope it has a solution to the problem.
I had no issues until today when booting up my system it simply didn’t power up! I removed the memory (G.Skill 4 16GB) sticks on my Asus Prime Z690-A Mobo and the CMOS battery. I installed them back after 5 minutes and the BIOS screen popped up, made adjustments mentioned above (XMP 1) and saved it and still an issue. The only way it will boot up properly to windows is by removing the memory sticks but one. I didn’t have this issue before and it ran beautifully with 64GB of ram until today.
This isn't limited to DDR5, or Intel, XMP always was dodgy with more than 2 sticks... It's a synchronization issue... Sometimes you can get around it by shuffling the sticks around, sometimes you can relax the timings manually, sometimes you can lower the frequency by 100-200MHz and then it works fine. Try your XMP 6000 setting, but manually set the clock to 5800 MHz instead.
Unstable tried
Indeed, I am having the same issue with 4x32GB in an AM4 B550 board with BIOS from August 2023. Runs at 2133, won't post at 3200 (the one XMP profile).
I haven't tried anything in between yet.
The RAM is Corsair CMK64GX4M2E3200C16. If you dig, 2133 appears to be the highest frequency at which it is guaranteed to run. It's a scam. They advertise the memory as 3200, include that number in the article number and what it actually means is "if you have no more than two DIMMs, of not too high capacity/density, with a bit of luck you may be able to overclock it to 3200 MHz and make it to a desktop without crashing".
AMD 7950x here with 128GB (4x32) G.Skill Flare X5 on ASRock x670e, I can occasionally boot with AMD EXPO for my ram but have experienced memory corruption (confirmed with memtest) so I disabled it. The extra speed would be nice but the capacity is essential for me.

Depends on the bios. Some versions of bios wont allow it properly due to new updates for newer cpus for the MB. I found with mine, i had to manually set the ddr voktage up .2 volts when using XMP. Older bios, xmp will work without voltage change. Something to do with bios uogrades and cpu compatibilities.

BIOS version?
@@fabiob9147 Using latest BIOS version
from what i have heard lately, it is about how 32GB+ sticks are DUAL channels which max out the bandwidth. anything else "overloads" it and really doesnt make much of a difference. i am completely new to the DDR5 quirks but it makes sense. i found that corsair currently sells a 4 stick kit BUT its only 8GB or 16GB but they are only single channel sticks. from how it was explained in a video, a single channel is writing or read only. dual channel can read and write at the same time. there seems to only be 4 channels for a 4 DIMM mobo. the only way that a lay man like me can think of is that mobo will have to have 8 channels for 4 DIMMs. however, i think that would impact the cpu and mobo development quite a bit. hope this might make a little sense.
PS- single channel, the ram chips are on ONE side of the stick. dual channel has ram chips on BOTH sides.

Iv had days where I tune it and it runs great all day all 4 sticks but usually on restart or idle it crashes and goes into boot loops.
Upping voltage helped, I’m going to try a few different things but this process is lengthy
I bought my X570 PC before I was aware of the limitations with regard to populating all memory slots. I should have bought 2 16gb sticks. The memory controller has a tough time with maintaining a 1 to 1 "Infinity Fabric" (1,800Mhz) with all memory slots populated. 16gb sticks were somewhat rare and expensive at the time. I bought 4 sticks of 3,600Mhz c14, 15, 15, 15, 35 (Samsung B-die), and though I could get all 4 sticks to operate at their XMP profile, I had WHEA errors. They were incredibly intermittent- sometimes going for days without a reboot even though correctable WHEA errors were happening in the background all the time. This lasted through several different video cards, and 2 CPU's- as I had a 5600x prior to the 5900x. Recently, I bought a new GPU, and while changing it my water pump died.
While replacing the water pump, and the GPU, I accidentally ripped the 5900X out of its socket without releasing the bar- ouch. This happened because of how damn well the Thermal Grizzly pink thermal paste was adhering between the CPU, and waterblock. While simply trying to remove the water block, it pulled off the CPU with it. However, there was no damage, it just cleaned the pins, even scraping off a thin layer of gold plating(I wonder where that went). I crossed my fingers and reinstalled everything, and thankfully it posted, and booted just fine, and low and behold- no more WHEA errors.. It's been almost two weeks, now. What the hell? Was one of my pins dirty, and not getting good contact?! Now I'm afraid to change anything.
What I love in the Windows ecosystem is a plenty option of customization and upgrades which is similar to car or motorcycle modification.
For some reason, I couldn’t change anything in my Gigabyte Bios.
But after I unplugged the battery for 20 seconds, with no power cable and turned on my PC with all 4 Ram blocks. It worked perfectly 🙂
Issue with 7950x and 4 stick
Just built a system with 128GB DDR5 based on 6600 sticks. Can boot Win11 at 5400. Knew I have to sacrifice clock rate with 4 sticks. Finally can be stable at 4800 with aggressive latency parameters (tCL-tRCD-tRP-tRAS etc.). On the future upgrade path from 64GB two stick, I'm unsure if I can get the exactly same 64GB sticks later. So might as well get 4 sticks now or none.
Having the same issue as well. Bought four; worrying in future no being able to procure
Thank you, you're the only one I've found answers the question 2 vs 4 DDR5 sticks
thnk you !!! I'm became crazy with my 64 kingston 4 dimm you are the first you tuber than speak about the problem DDR5 and XMP DON'T WORK 4DIMM
I got a 7800X3D. I went with 4 sticks of T-Create 6000MTs CL30. I get weekly blue screens. Surprisingly stable since it's only weekly. I can work hardcore creator workloads for entire days straight with no issues, but once a week I'll be randomly hit by a blue screen. I've ruled out every other possible cause, and none of the RAM sticks are bad. This is my first time going with 4 sticks and now I wish I went with 2 lol, but I am experimenting now with trying to get it fully stable since it's been surprisingly stable otherwise. I've rolled by speeds to 5600MTs to keep the timings, since AMD seems to respond better to low timings; as opposed to higher speeds. If that doesn't work I'll try 5200MTs at CL30. If that doesn't work maybe I'll try CL34; basically copying the 2x32 spec from teamgroup. If that doesn't work I'll try 5600MT at CL40, or take half the sticks out and call it another learning mistake in PC building lol...like when I built my first & only dual-GPU PC in 2012.
update now you can launced 128gb 4x32 at 5600mhz
why did you get this instead of the 7950x ?!?!?
I actually bought 4 sticks of that exact Kingston Fury DDR5 RAM up to 128 GB but haven’t built it into a system yet. Are you saying that without XMP (at base speed) it will be stable but it just can’t be overclocked? If so, that’s not the biggest deal for me since my workflow just requires the capacity to hold lots of music samples. I wasn’t planning to overclock. Are the sticks stable without XMP?
yess sure, it just can't run the xmp. with the stock speed its just fine
I think we need to see you build the ASUS Z790 Creator mobo, with the I9-13900k CPU and test 128gb DDR5 with that. If it works that's what I'm buying!! 😀
How much speed do you expect?
I agree keeping the BIOS up to date is important. It can sometimes have a bad effect if a system is already stable but on new/cutting edge tech it often solves more issues than it causes. As a tip: I found a need on my ASUS boards to also do a clear CMOS and reset to default settings before reconfiguring all the settings again as this had a material impact on performance and stability. Reloading saved profiles or not loading back to defaults would sometimes see strange behaviour.
When you update the bios tbe saved profiles are removed and a cmos is done automatically for you.
I learned the hard way and lost all my configs / oc undervolt but figured it back out 😂 and took screenshots of my uief settings
Agree, it wipes the saved profiles when doing an update. I loaded my saved profile from a USB drive I had exported it to assuming it would be fine and found it wasn’t 100%. Reconfiguring the exact same settings after a Clear CMOS manually resulted in a much better stability and slightly more performance.
@@Matty-rn5gt yep this is exactly what happened with me so I just took screenshots of my settings
I was looking for 4 x 16GB or 4 x 32GB kits and there's literally nothing. That the motherboards are advertised as 128GB capable with RAM kits on QVL is hugely misleading if not downright false advertising. How does one get 128GB @ 6,000mhz DDR5 today? You can't. Interesting video!!

This was surprisingly entertaining to watch someone perform the little tedious details to make a machine function properly. Which is something I do often. Good information. Thank you.
Haven't been able to boot with x 4 DDR5 sticks at all on my asus B660 at all. Just with 2 sticks 5200mhz with xmp. Tried boot without xmp aswell and no booth with 4. Bios is also updated. But with x2 xmp it was fine.
I have the same issues as you describe with my 4x16gb Corsair Dominator 5600mhz. They run at 4900mhz to be able to work without crashing.
i agreed with all your comment, 4x DIMM won't work stable for long .. although you have pass all memory test doesn't mean you can pass with your daily work. for my case, i had to left it with 2x DIMM and set myself limit
I'd love to take the plastic off my ram sticks, and put some all metal heatsinks with optimized topology for moving air, and then just slap a 4 slot ram cooler on top. I bet we could really push the limits then.
4x16 6000-CL 36 and no issue here, and they are two diferentes GSKILL kits 2x16 Trident Zneo, and 2x16 FlareX5, justs first boot with neo ones, let the bios tranining to finish, and reboot with 4 slots populated, no issues.
Thanks for the in-depth video. I got a Ryzen 7590x setup myself with 2 sets of 2x32GB kits. Even at the stock bios speeds it was very unstable, and I ended up returning my first motherboard because of it. Having the same issue on the next board, I ended up having to de-clock and up the voltage on the RAM manually to get it stable. So far I have 4200MHz at CL32 stable. Far from the advertised 5800MHz on the sticks. I do hope this is all fixable with future updates, and not hardware limitations.
Not even at 4800 stable? I'd totally go for it they worked without XMP at that level, but 4200 CL32 is basically 2x worse than 3600 CL16 😕
@@ChatGTA345 with the latest bios update, I've been able to get 4800 cl 36 stable, but I had to increase the voltages and go up to 1.4v to the sticks.

I was able to get 4 chips to work on my pc a little more stable by going into AI Tweaker\Advanced Memory Voltages and under PMIC Voltage, you select By per PMIC
Did you enable XMP?
Crucial uses micron for their ram, which is more stable than Samsung or Hynix. But cannot be pushed into higher speeds like them so you are unlikely to see anything above 5600mhz from them for now. So they can have a higher jdec spec than 4000.
As far i remember from the 12th gen cpu reviews, tt's not a matter of ram or either motherboards. It's the cpu that doesn't support 4 stick of memory in xmp mode
considering gskill already has 7600MHZ CL36 ddr5 ram available. this issue needs to be fixed ASAP.
i saw similar issue earlier on other video called "Be Careful Before Buying Intel 12th Generation Memory(i might be wrong)" on a JayzTwoCents channel, he also tried to boot with 4 sticks at full speed and motherboard failed that. Also i read some "theory" in discussions about that, and it seems caused by low count of PCB layers/trackways. Actual/current boards only have about 8+ layers(i might be wrong), so there a required more "thicker" boards with more layers/trackways, and i hope that will become with 700-chipsets. That's why i decided to skip DDR5 on the 600-chipsets until 700 come out, and save some money by pairing 12700k with DDR4 board and RAM that i already have.
I bought a new build with a Tuf z790 plus wifi motherboard, I7 13700k cpu, Gigabyte RTX 4080 OC and a 2x16 32gb Corsair Dominator 6200mhz ddr5 kit.

@@pmcomputing2459 That's very weird, isn't it?
@@n4ul17o yes but apparently thats just DDR5, not sure if correct but the way I understand it is that it needs the extra latency because of how fast it is.
Be warned if you update your bios you lose your old bios settings. So record your settings before updating! Also just buy larger 2x capacity sticks. Also if you buy a k series cpu then you fine tune that so there's no reason not to fine tune your ram. Try loosening the timings (if it won't boot) the last tip I'll give is don't buy dd5 in the 1st place 🤣🤣
Hey i just installeed 32 more gb ram into my rig with 4 sticks instead of 2
Had no issue with xmp on 32 gb but after getting new ram my pc restart alot. What Can i do?

Even after all this time , ram, cpu and boards manufacturers really need to solve this with 4 sticks!!! 4 sticks! 128 Gig still will not run at 5000 or 6000 very disappointing
I wonder if 13th Gen and Z790 will be any better. Or if anyone finally brings out 64gb sticks to get 128gb
I think we will see that in time. I believe DDR5 is capable of up to 256gb per stick.
Ditto. I hope we can get that tested when the 13th gen and Z790 come out next week. Anyone know if there's been any announcements for release dates for 64GB DDR5 sticks?
@@birdman8125 256gb per stick? 🤣🤣😭 are u talking about ddr9 in the years 2045??? 😭😭
Buy your memory based on your own requirements (i.e. understand your workloads). If you need capacity (especially the max supported by the platform) you will not get JEDEC defined standard speeds. If your workloads are latency sensitive you should target a single stick per memory channel. Ranks might also play a role here, but it will depend on platform. Each generation of CPUs will come with improved memory controllers. Intel 12th gen can do 4800, AMD 7000 series can do 5200, rumors suggests that Intel 13th gen could do 5600. This will probably slowly go towards 7200 (but will take years).
Hello. Do you think the DDR5 would make a big difference in comparison with DDR4 using i7 13th g. and Z790 motherboard for music and video production? Worth it?
why not just use a z690 should do the job just fine with 13th gen
Not work with 4 !!!

Here is my janky solution.
Using corsair 6000 mt/s RAM 32 gb, 2 sticks on a TUF z790 PLUS WIFI board.
XMP doesn't want to boot? If you're using corsair RAM, make sure ICue is installed (the software that controls corsair products such as RGB lighting and for some reason, RAM).
Then go into bios, turn off xmp in easy mode, then go to the AI tweaker in the advanced settings and manually set the DRAM frequency to whatever your kit allows. Don't change anything else.
For me this has led to the RAM working perfectly with every setting left on automatic.

I have the same specs as you have, the exact same Kingston Ram, even the same GPU. I only have a different CPU, an AMD Ryzen 9, 7900x cpu running on an ASUS Prime B650-Plus. According to specs this board also supports that ram, according to the QVL. I have not been messing in the bios at first. Tried 64GB, ran perfectly fine at 4,800Mt/s. Then added the other two dimms for the total of 128GB, but my pc wouldn't boot. I tried turning on Memory Training, but I simply could not get into the bios. Only when removing two dimms it worked again. For me it's not even needed 4 dimms running at 4,800Mt/s. If all of them ran at 3,600Mt/s it would be fine as well, but also this combination is not working. And, I did upgraded the bios a few days ago. It could probably be the motherboard, which is not the most expensive board, but one could assume if the specs say, it can handle 128GB, it should be able to handle 128GB. So currently I have 2 (expensive) Kingston dimms lying here collecting dust. Any suggestion how I get 4 of them working? 128GB on 3,600Mt/s is faster than 64GB on 4,800Mt/s. It did work for a while, but I noticed after the bios update (when all settings are reset, and of course the 4 dimms were set back to auto, the pc refused to boot again), that after removing the 2 extra sticks my video editor is working a lot slower. I do a lot of video effects, encoding on 4K video material. Any suggestions on how to get this working?
Why are 4 sticks (128) at 3600 faster than 2 sticks (64) at 4800?
So useful. Thanks for the explanation 🙏🏽
What about 13th gen? Same issue prevails? The issue is only because of the motherboard??
Do you plan to test the crucial 128Gb, which have default speed @4800? It's also listed at the Pugets recommended system for Davinci resolve. Thank you for all the info, keep up the excellent work!
tried running 4x 16GB @ 7200 on 13900K ... it will boot. But as soon as any serious load on the system it will crash. I think I will try to bump it down to 6800 or 7000MHz. It seems like it's almost there. It runs perfectly fine @ 7200 MHz with 2 sticks.
What's your board?
