I wish Buildzoid would make a small PSA about power down mode. Memory context restore MUST be disabled if you disable power down mode, or you will bluescreen. You will bluescreen so bad that's if you manage to get into windows, wonder why, and think it's these memory timings. No, it's power down mode. Go ahead and disable power down mode, but ALSO DISABLE MEMORY CONTEXT RESTORE. MCR on auto, or enabled along with power down mode disabled will cause massive issues. You sacrifice slightly faster boot times, in exchange for ditching power down mode which slightly harms memory latency performance. Please like this post get it to the top, save folks a lot of headache.

This mostly worked for me. Wouldn't boot into Windows. I added 25 to each tRFC to get it to boot. Now, to test for stability. Currently at 6400 MT/s and 2133 FCLK.
@@lsik231l Hey, I think there's a small misunderstanding. The unit of timings are actually clocks - so the faster your frequency is, the looser your timings have to be. That's because the RAM still needs the same actual time for certain operations (a timing is basically how many cycles a certain operation needs) So if you have Hynix and it's rated for higher speeds than shown in this video (6000MHz), you're gonna have to loosen timings. You may be stable on the timings you have set right now, but I'd really test that with proper stress tests (TM5, HCI Memtest, Karhu (paid), y-cruncher, prime95 Large, OCCT CPU+Ram Large, etc)
I confirmed I have hynix memory in Thaiphoon Burner but these settings didnt work at all, when it rebooted after saving just the dram LED comes on. Any ideas?
For the longest time I tried to enable EXPO on this same motherboard without luck. Crashes, bios updates, BSOD, etc. I got a different ram kit (which happens to be the same one you got). I used THE EXACT SAME settings you have and no issues since then! I really appreciate it! I have another build but that one has Samsung die which would be amazing if you could “build” expo settings for it since it is the exact same issue I had but on that build. Again, thanks!
I really appreciate the videos where you show timings that should be valid for a particular memory module/manufacturer. I used your videos applicable for 3200 CL14 b-die for ryzen to OC to decent timings 3800MHz cl16 and it worked fantastic.
Hi Buildzoid, love the thorough testing of how to get our Hynix RAM in order. Thanks so much, normally never comment but frankly you more than deserve the like + comment engagement for the algorithm.
Appreciate the video. The reason why 2033FCLK is faster is because the memory is implicitly run at 6098-6100MHz. The Agesa BIOS versions appear to do this. If we set the FCLK to 1 step higher than the MCLK/1.5, then it'll advance the MCLK to match. This also occurs at 6200MHz with a 2100FCLK, which will result in a 3150 MCLK. We can see this effect if we use ZenTimings. This gives precisely a 2:3 ratio between the FCLK and the MCLK. Yes, while that's not an even ratio, it does mean though that for every 3Hz on the MCLK, that the FCLK is directly in sync at that precise moment leading to improved behavior. A better ratio would be to have FCLK be half of MCLK, but since the MCLK speed is generally limited to 3200MHz at most, the reduction in FCLK speed harms more than it helps. Maybe Zen 5 will be about to hit 4000MHz MCLK, and if so, that'll be the next "sweet spot".
For whatever reason, 2033 is a good bit slower than "AUTO" for me on the MSI MPG B650I mITX board. All of these timings worked for me other than tREFI (MSI does not list it on this board yet iirc).
@@jesusraya4484 what do you mean how do I test? It would crash at 2033 on my mobo. And yes it will improve frame rates. Way less so if you have a X3D chip though.
These timings worked really well for my budget hynix based sticks. Saw a signifigant improvement in Aida memory benchmark, and so far stable even with my DRAM voltages set at 1.25v which is what my kit is rated for at xmp (my ram doesn't have expo support) , Thanks a bunch!
I was able to replicate the exact sub timings on my 13900K system with a G.Skill 5600 CL30 kit (that I tuned to CL28) and it passed all my tests. Reduced the memory latency in AIDA from 67ns to ~61ns. All without touching any voltages. Neat.
Thanks Buildzoid, I followed these settings for my ADATA 64GB XPG Lancer RGB 6000MHz DDR5 on a Gigabyte B650 Aorus Elite X motherboard with a 7800X3D. My system seems stable with VSOC of 1.2V (was too scared to bump it up higher due to exploding CPUs) and VDD of 1.35 (as per EXPO profile). One thing I found different is that for my Tras, the lowest value I could set was 76. I had no option to set it to 28.
Thank you very much for this. This solved my CL30 6000 hynix woes. The expo profile was simply not working on my MSI B650I Edge Wifi and this guide fixed it in one go. So far very stable running memtest. What a lifesaver!
As always i appreciate your content and im happy to see you seem fine after the break :). The reason why 6000 2033 works better is because the A+D agesa has a bug where on some frequencies combinations the actual frequency increases eg: 6000+2033 = 6100 (3050 uclk) 6200+2100= 3150 uclk, 6200+2133= 3200 uclk, 6400+2167 = 3250 uclk. right now I'm able to run 6200+2100 ( which due to the bug with 6200+2100 runs at 6300) with 1.4v on memory and 1.25v on soc, testing to see if I can go lower, 6400 booted but kinda unstable not sure it's vsoc or primaries or rtts tho
oh great,i just noticed he is using agesa 1003, so yes,you are right, that also means that the info about 2033 fclk in this video is already outdated because that bug is fixed in 1004.
I'm on 1003 and there's a noticable improvement. Using a KIngston 64 Gb kit at 6000 MHz, with tight timings. I'm not knowledgable enough to see how 1004 would change it. Asrock didn't release 1004 (yet?).
My dumbass bought XMP ram on my AMD build, and this guide got me through hours of issues with ram timings. 10 years since my last build. Got it running at 6200! Thank you.
Be carefull setting Power Down DISABLE on certain motherboards. Here on B650 Tomahawk with M-Die ram kit if you set PD off and CMR on it will lead in bsods and boot corruption, so POWERDOWN need to be ON if Context Memory Restore is ON. If you corrupt boot with bsod at startup do this: tap F1, then Prompt Command and type exactly this: BOOTREC /FIXMBR, press enter, then type: BOOTSECT /NT60 SYS, press enter, then type: BOOTREC /FIXBOOT, press enter, type EXIT, enter and reboot. Now boot is fixed and windows will start. Thanks me later :) This should be put in description
My system crash like crazy with PD ON if I'm using Buildzoid timings but when I'm using EXPO then I can turn it ON. I don't know what's better EXPO with MCR ON or Buildzoid timings with MCR OFF. The difference in boot time is big 16s vs 56s
Thank you, thank you, thank you!! This is the second time using these timings whenever Expo is not running stable. With these settings, and using the EXPO timing, with G.Skill 64GB (2x32) 6000 CL32 on a Tuf B650 plus-wifi, I am having no more crashing, or boot errors. Last time I had to use these eventually BIOS updates came out and I was able to use the Expo settings with no adjustments, but until then, yours run flawless as is.. and they are fast!
This video probably saved me and and my house from catching fire, I'm glad I instantly applied these settings first thing first back when I bought my 7800x3d, it was before all the reports even came out. Thank you.
I've been waiting so long for this. I have that exact mobo and F5-6000J3238F16GX2-TZ5N ram kit. Running all your settings but primaries are a hair tighter.
Pretty straightforward, even easier since we pretty much can use same settings as shown. About a 9% faster ram for me and my latency went from 85ns to 70ns. Thank you!
I couldn't run Windows without errors using Expo and these timings sorted me out! Thanks a ton! I was planning on returning my RAM prior to this. 24GBx2 6400 kit running at 6000 for the record F5-6400J3239F24GX2-TZ5NR
Thank you! Working perfectly @ 6000 on my 4x16 Dominator kit! Might try to push it a little higher just to see what happens, but super happy that my board can do at least 6000 on 4 sticks at all.
I wish I could like a video 100 times. I was having a lot of problems with my new 7950X3D/GSkill Trident Z5 2x16GB build. The PC would reboot randomly when doing simple tasks like browsing the web or using light programs, would also error and reboot within seconds every time I started the OCCT memory test. I was certain either the CPU or RAM was defective and was almost at the point of returning one of them. Took me some good 3 weeks to find a post that said they had a problem very similar to mine and this video fixed it. I *think* the problem all along was that I enabled EXPO as soon as I got the machine built, but for some reason the preset didn't change the voltages to be able to handle 6000mhz. I have an MSI board and the VDDIO voltage is grayed out and cannot be changed without also changing the DRAM voltage manually. I think the EXPO preset didn't account for that. Anyway, thank you so much, I don't even care about overclocking RAM, I'm just glad the PC is working smoothly now.
Received my 7950X3D and the Kingston DDR5-4800 ECC 40-39-39-77 modules. Used your secondary timings, put primaries to 32-40-40-28 at DDR5-6000, voltages at 1.2V for VDDSOC (instead of 1.25V) and 1.3V for VDDIO/VDD/VDDQ (instead of 1.35V), and things seem fancy according to memtest86. Thanks for the help.
I am actually a little scared to change anything on the voltage as the 3d chips are very sensitive for these changes. Der Bauer even killed a cpu because of changing the voltages
Thank you for this guide!! I have the same motherboard and 2x16GB DDR5-6000 CL30 Hynix M-Die sitting around just waiting for the 7800X3D to release, - will try to replicate your timings!!
@@brandyyn If you're wondering what to get, I got today Kinston 5600cl36 (fury beast) 2x16 for 135€. Literally cheapest kit of +5200 kingston I could find. It's Hynix A die, lmao.
Like so many others here, I can't thank you enough. I've had nothing but issues with this new rig. Gifted my old one to my eldest. It was rock solid. Built pretty much the same rig (same mobo as this video), but went with a 7950x3d and 64gb rather than the 7800x3d and 32gb I used to have. Boy, I had buyers remorse. I even swapped the ram at one point. Trying to isolate the BSOD's... That did help. Was still getting unsafe shutdowns. That was actually a Windows issue (Fast Boot.... Giving driver errors) I've swapped PSU's (my son has the same), trying to isolate the problems. I was ready to send back the mobo... So I thought, well, why not give your timings a go. For whatever reason, EXPO on my rig was giving more voltage than your guide!! Not unsafe, but higher than what you recommended. I dropped my RAM from 6000 to 5600, to get better CAS, and other primary timings. My Cinebench 2024 went from 2024 (I couldn't get it higher!!), to 2132!!! On lower voltages, lower temps, a higher UCLK, and a Lower MT/s I have absolutely no idea what any of those numbers actually mean. Hence why myself, and so many others, rely on EXPO to them for us. And to be frank with you, I don't really want to learn what they mean, other than the basics, and that they work, and have improved my performance whilst lowering my power draw and temps... Why aren't you the ones setting the EXPO settings? Like seriously. These companies should be employing you as a consultant. My machine boots up in like 5 seconds now. I was ready to send everything back. I've had two months nearly of faffing around, not enjoying my PC, troubleshooting, reinstalling windows. I know more about minidumps and how to read them then I ever wanted to. When I was younger, I used to love this stuff. Now I'm older, It drives me up the wall. Dude, I owe you one
Copied these exact settings for a cheap Team Group 5600 CL32 kit and it works perfectly. I was even able to get it to run at 6000 without changing any of the primary timings.
FYI, disabling Power Down Mode made my system incredibly unstable - would blue screen on/just after boot over half the time, and even freeze in bios frequently. Took a while to narrow it down, but that seems to be it
Thank you for the heads up, I never considered that it could be the culprit for my crashes and freezes in BIOS. Maybe without it I can give it another try.
I have 2x16GB Corsair Dominator Platinum, CL30 version. Hynix. on Aida64 memory benchmark I got following results: Expo: Read: 77914MB/s | Write: 76244MB/s | Copy: 68462MB/s | Latency: 69.5ns Buildzoid profile: Read: 88496MB/s | Write: 92345MB/s | Copy: 79040MB/s | Latency: 61.8ns So definitely a huge improvement, thanks a lot for this video!
Just dropped in to say this works exactly as you describe it in the video. After stress testing and several hours of gaming, I have yet to have a lockup. Thank you!
Thanks, helped me a lot. Tried to get it stable with my 6400Kit but couldn't do it and had to clock down to 6000. Then as said your settings worked without flaw ! Massive 22.5% lower latency, about 18-20% for transfer speeds. I am just too stupid to understand the black magic behind this Memory Tuning stuff.
Thanks! This worked great on my 7800x3d and G.Skill memory! I bought the 6400 2x32 kit but only clocked it to 6000 and didn't have to change a single setting from your recommendations (obviously except for my primary timings) Thanks for the help! Super stable overclock!
Did you happen to get a 6400 CL32 kit from G.Skill? That's what I'm looking at though I don't know that the motherboard I'm going to get for my 7800X3D actually can read the XMP profile to pull the primary timings? Figure 6000 CL30 would be easy, maybe even lower since I'm just hoping to get Hynix A die.
Which one do you use? I am planning to buy a 6000 CL30 G.Skill for my 7800X3D but some variants are hard to come by in Germany especially a White RGB model.
on my A-die Kit, I can get 4-4 TRRD's working and 8RTP. The main thing is you have to raise the SOC voltage ever so slightly and it will start working. I had to set mine to 1.22 to get it stable. If i tried 1.2 I could only get 4-8 stable, Ran Y-cruncher/superpi/linpack/occt for many hours just to verify that 4-4 was stable. Figured I would share since I had the same issue with My TRRDL/RTP not cooperating.
@@nguyendinh2052 for me voltages really were the main key. Cause just like you my A-Die at certain voltages didn’t cooperate at all with anything below 4-7. So maybe try increasing it even more. And see if you hit the sweet spot.
Buildzoid!!! Your guide saved my 7800X3D from burning out. So happens I was using the same SK Hynix Intel RAM as this guide. And setting the Mem controller voltage to 1.35 prevents the burnouts from happening
Better waiting for official statements about this shitshow. I completed my build 4 days ago and had to update bios 3 times since...Btw, using this memory timing is stable according to many users including me. Still, haven't heard any of them talking about their Mobo and CPU being burned, mostly from EXPO users.
In light of the memory voltages being the rumored problem child for X3D CPUs dying, do you still feel good about the 1.25V here? And what of the other voltages? I think that's lower than what it's rumored to go if you leave it on EXPO.
Can confim that i can replicate this exact settings using ADATA Lancer AX5U6000C3032G-DCLARWH (32x2Kit, 6000Mhz, Hynix A Die), everything is working great as well, i don't even need to change DRAM Voltage. Thanks a bunch Buildzoid!
@@Drachenmaetzler I have the newest version installed. Funnily enough the newest BIOS seems more unstable than the last even though I waited for it to not be the beta version anymore. But by changing the Timings I at least can have both EXPO and Memory Context Restore enabled without any issues or blue screens like before. Also I have seen people on Reddit saying they got their system to boot instantly by changing the timings to 36-36-36-72. Unfortunately didn't work for me.
Thanks for the video. I applied exactly same setting for my pc, working flawlessly so far. My setup is like this : 7800x3d, Asus ROG STRIX X670E-E BIOS 1416, Kingston DDR5 32GB(2x16GB) 6000MHz CL40
@@ksenchy yes, on a Strix X670E-E and a 7900X Had to drop to 5800MHz though, as I was getting errors with 4 sticks. But it is stable with 2 DIMMs at 6000
That's what I was going to ask you, I'm thinking of moving AM5 and going 4x16GB and I can't get any serious answers if 6000 will be stable with 4 sticks. All these TH-camrs and media outlets only test 2 sticks 💩 There are Corsair 2x32GB at 6000MT/s sticks but oh boy CL40 sounds horrible. I'm not buying any other brand as no other has hardware RGB profile support. I don't know, wait another generation so AMD improves DDR5 memory controllers in next generation or win a silicon lottery so I can run 6000 stable.
@@5pyR17US I have the exact same setup than you, but I can't get EXPO working on mine for nothing with 4 modules (it works with 2). Did you only have to drop frequency to 5800MHz to make it work or there was something else? I also wonder what your BIOS version is. Any help is greatly appreciated. I can't get my ram to get past 3600, which is a bummer.
@@icarus33 1416 is the latest bios allowing my RAM to remain stable with 4 sticks at 6000. After this one it was impossible, no matter which settings I tried. I ended up buying 2x32Gb instead and since then my setup is fully stable with these timings at 6000MHz
With my 7700x, Asrock b650e Pg Riptide and Hynix A-die (2x16) I've spent several hours to optimize timings one by one and I came up with the same values. In my setup the FCLK is stable at 2100 and Trdrw can easily go down at 14. Unfortunately at the moment Asrock bios doesn't allow to modify Trefi.
So fantastic your video, you saved my life, I tried to upgrade my memory with 2 additional 16Gb DD5 Lexar Ares, identical to the first 2 I already had and there was no way to run this memory at decent settings. I was worried to have to accept much lower speed to increase my memory. I know that 4 modules configuration is harder to get to work with XMP, but your settings allowed me to run then at 5600 Mz instead of 6400 but with tighter primary timings resulting in identical if not faster results than with only 2 modules, great job !
Used the exact timings on my rig and got a noticeable performance boost over the regular XMP. MOBO: Asus TUF GAMING B650-PLUS WIFI CPU: 7800x3D RAM: G.Skill Trident Z5 RGB 32GB DDR5-7200 CL34 Memory
got essentially the same ram from a different company, did u change your primary timings to what's shown in the video or nah? And did u put it on 6000mhz + 1.2V?
[First time PC builder] Glad I came across this video. Couldn't get past 5600Mhz with default expo settings, not sure what was wrong there. But with these timings 6000 seems to be running smoothly with ryzen 7900x and asus x670e-a.
After hearing that it is very difficult to deal with ddr5, I did not expect that it would be so easy. Thanks for that. can you share 7950x settings for Asus motherboard for the safe and better multi-core performance?
My PC with EXPO on was freezing after some minutes on windows and restarting without a blue screen, I set these timings and for a good few hours it still didn't happen again. I have a ryzen 5 7600 with teamgroup 2x16gb 6000 cl30. Thank you very much for sharing this information and allowing many people to solve their problem!
Great videos, thank you so much for this easy to follow instructions and making DDR5 tuning easy. Geekbench will immediately show the benefits of low latency in their results. It worked perfectly in my 7900X system using Corsair (Hynix) DDR5. Great performance and stability!! 💪💪💪 (OCCT doesn’t seem to like it though… weird program)
Hi sphaera, I have a similar system to you. Do you mind telling me what Corsair memory you're using? I have the vengeance 5600 c36 and want to check before I implement the settings.
Thank you so much for these, I'm using four sticks since I didn't know about the issues before hand and was having immense trouble getting my system stable at anything past 5400MHz, with these settings so far it's been stable at 6000MHz running tests for an hour or so, before was getting memory errors within few minutes. E: Seems my system is stable at 6200MHz memory speed with these timings, absolutely magical.
Very interesting, with your settings I'm getting about the same bandwidth as I was able to get with 6200 and 2066 fclk but slightly lower latency with less voltage. Good ram diet.
thank you man. I've heard mentions of you all over the internet and then I found you here... fingers crossed........ this computer was way too expensive to just have it run okay-ish most of the time... ya kno
Thank you for your time and effort! I would love to see timing setups for Samsung memory. EXPO is not really working for me with Corsair's CMK32GX5M2D6000Z36 Kit, on my ROG CROSSHAIR X670E HERO mb.
Bit late with the reply but I had the exact same issue with the same kit, swapped it for G.Skill F5-6000J3038F16GX2-TZ5NR as i was in the returns window and so far it's been great
Have any of these recommended settings changed with the new AGESA? Curious to know how it has affected them and would love to see a new update video on it.
Thanks for this Buildzoid. I ended up here mainly because three different memory kits wouldn't hit their rated speeds. I had issues with the Samsung kit I had hitting anything over 4800, let alone the EXPO profile. No matter which BIOS I've tried no kit I've had will do anything over 5800, which makes me feel like it's probably my luck in the silicon lottery on my 7950X. Regardless, this helped me tighten the timings if nothing else. EXPO results in unstable memory for me.
Very nice timings and easy to run. I've tried to lower the voltages and I am able to run them at 1.1v for SOC Voltage, chances are that the MC voltage can be lowered as well.
Nice. You're right, VDDIO/MC and VDDQ should both work without issue at 1.25. My understanding about SOC is that the amount you're able to lower it varies by individual hardware. Most should be able to do 1.20, some (like yours) can do 1.15 or 1.10.
@@subaction I'm doing 1.1v SOC and 1.2v VDDIO/MC. But for the ram sticks themselves I can't go lower than 1.325v without Y-Cruncher giving errors after some hours.
Helped a lot thx! My Dominator 6000 didn't run on my X670e creator with standard DOCP 2 and much higher timings, than in your tut!! Now timings are much tighter and it runs smoothly
These settings also work for 6000MHz 2x32gb which are dual rank. Only thing different i did was oc to 6200mhz and dropped tcl 30, trp&trcd 37. This was on a 7800x3d oc'ed to + 5% and vsoc @ 1.26 in bios and under heavy load doest go over 1.305v in occt but aida64 has not exceeding 1.296v.
Couldn't take the long boot times. Set memory context restore and power down mode to enabled again. Fixed boot times (about 35s). And latency only went from 61ns to 63ns.
Any change for revisiting these? Asus X670E Plus and BIOS 1616 these no longer work :( No issues on older BIOS versions, on 1414 worked even with 1.25SOC.
You sir are an absolute legend, I was ready to return my kit but said it was worth a shot to try your settings. Save and restart and guess what it booted up right away. A blessings from the lord 😂😂 Thank you, life saver.
Can confirm asrock riptide + tcreate runs these settings flawlessly. Saw massive improvements over stock expo of 6000 and cl30. Subtimings is the key, it goes beyond benchmarks... I can feel the snappiness opening programs and basically any task. I have a 7800x3d also, and collectively I feel the change.
Used the gskill 6600mhz cl34 1.4v kit as an a die source on my msi x670e carbon. It performs amazingly. Oddly though, my board would not let me set tras to 28. For whatever reason the minimum value the board would let me set was 30. Still seems to work just fine though.
Disabling EXPO and setting those timings (only difference is I didn't had the option to 28 so I put 30 on tras) just solved my problem. No more crashes!
@@ActuallyHardcoreOverclocking Hi, I copied your settings and got an overckock that seemed stable on Windows 11 because the computer wouldn't restart. However, when playing a game like halo infinite or battkefield V for 5 minutes, the game ends up closing. With other types of overclock the computer was restarted, which I consider more unstable. How can I keep similar values and prevent the games from crashing? I don't know what value to start changing or raising again or what you can advise me to try to find stability in games. Currently I tried other settings with my same RAM from a web and other secondary values and I got improvement, but without a doubt yours was the best. of 70 ns with the Expo value of the latency ram at 56.7 ns, a beast. The reading and writing speed also increased by about 400 points. In games, the performance improvement is noticeable a lot, especially in CPU-dependent games, I made comparisons and the average, low and maximum fps increased a lot. For this reason I do not want to give up your magnificent overclock profile, and for this I want you to advise me what values or value I should go up little by little to find my point of stability. My ram is a Flare X 6000 CL32 32-38-38-96, and the primary values that I set along with your overclock were 28-36-36-28. The overclock that I was trying previously was the one in the following link: www.techpowerup.com/review/g-skill-flare-x5-ddr5-6000-cl32-amd-2x-16-gb/8.html which was stable if I applied only the primary values, but when applying the secondary ones the pc ended up restarting at some point.
Hardware unboxed will be releasing a video on this shortly. It's already available on floatplane. Long story short, these can make a 5200 cl30 kit perform similar to a 6000 cl30 running expo.
Just achieved your exact settings on a totally different kit, albeit with Hynix (A) memory. T-Create Expert 64GB (32x2) 6400 dual-rank on a 7500F. Even the primary timings worked (though other's mileage will vary). Tested with Y-cruncher only, then played FC5 for a couple hours. Thanks a lot!
Thank you so much for this! I used your settings on my G.SKILL Trident Z5 Neo DDR5 6000 64gb kit and went from read rate of 70,238 MB/s to 84,750 MB/s; and latency of 69.1ns to 59.4ns. One question I have is on my Asus x670e Hero MB, the CPU VDDIO/MC voltage, when I set to 1.35000 V, it changes the value to something like ~1.35663V. Does this matter?
I'm glad i check out this video even if i don't have a ryzen 7000. One of my friend asked me why his pc was failing the memory initialization every day. Well, thanks for giving me the right answer without asking!
After searching the web high and low I am back where I started my journey. Been lookin' everywhere and anywhere on why my system was still crashing after hours of stable stability testing. Lo and behold Buildzoid tells you right at the beginning of this vid that the GPU's been the one that's been cooking my DDR5 ram kit and just hard shuts down my PC. Stability test that always came back stable. Not knowing usually the GPU doesn't get stress tested in these tests and therefore doesn't cook my RAM kit. But after an hour or hrs gaming my PC just been crashing. I played with voltage, temps, limits, underclocking/overclocking, nothing made a diff. But here Buildzoid just tells straight up why it happens. Damn it all those wasted hrs. Didn't even think of the GPU that could be the culprit. Ty Buildzoid 🙏forever in ur depth. K now I gotta figure out a way on how I can prevent or reduce the cookin' of my RAM kit. Peepz listen to every word Buildzoid says! Don't just skip to the good stuff. His wisdom knows no boundaries.
Got a minor problem when applying this with 5600Mhz Kingston Fury 2x32GB on Ryzen 7900 non-x. Blips of green or white happens inside Windows 11 once in a while. I will investigate, do you have any idea why it could be? Seems like something interacts with the iGPU (not running GPU). Would the SOC voltage have to be even higher? Thanks for another amazing video! Favorite overclocker!👍 EDIT: tRAS was the solution! Increase tRAS to 36 7900 non-x, MSI B650I Edge, motherboard limits
I have the same set, need to try this out. Can we apply same/similar settings as in the video even tho our ram is 5600mhz and not 6000mhz? Thank you in advanced…
Dude I just want to tell you what an absolute LEGEND you are. I've been struggling with a similar issue for days now, and all other mentions of it online just lead to "turn off EXPO". You didn't have to come back and update your comment with the solution, but you did. And for that I am genuinely grateful. Just to add my experience in case it helps some lost soul: Kingston Fury Beast 6000Mhz 2x16GB, Windows 10, Ryzen 7600x, screen would flicker or flash black when on igpu. tRAS is the solution.
@@perthhi1 thank you! Actually I adjusted my primary timings to be 36-38-38-38 this is as low as I feel comfortable going with this 64GB kit but its been y-cruncher memtest tested for 30 days of 2 rounds both VST alone and the memtest config with AVX512 so 60 days total its rock stable!
Great and useful vid BZ, appreciate it! Any thoughts on GDM setting (ADDR_CMD_Mode for ASUS). I've read that disabling it (setting to BUF) can improve latency? P.S.: Would be awesome to get a vid on how to best push m-die to 6200/6400 with emphasis on MC, IF and CPU voltages.
At least on zen 3 it was know to improve performance because GDM does some strange interactions with command rate, so even if you had 1T on the command rate, in reality it was performing like 2t (or worse) if the GDM was enabled
@@temporoyale6251 GDM On is more like 1.5T and gives you ability to get some higher MHz and timighter timings to boot, it's not worse than 2T for sure.
@@Kestrelms yeah, you are right, but I remember a know memory overclocker (Veii) testing the performance of GDM, and in some cases, not all, GDM on would perform worse than 2T
@@Kestrelms i can back him up GDM ON does indeed have some horrible flaws when you overtight some timings like tRRDL 4 instead of 6 , tWTRL 8 instead of 10 and tRDWR / tWRRD ratio if you use lower tCWL than tCL. might be just a dual ranked issue. in my experience i would use a lower frequency with gdm off than a higher one with gdm on. might be a specific motherboard / ram issue, might be something else but the issue is there. Edit: GDM ON feels like a fake stable settings on some rare situation, doesn't throw errors but gives significant worse result than 2t.. not to mention 1t pure. For some reason most overclockers and AMD recommend GDM ON for Dual Rank kits, based on my experience i don't.
Seems not to be working anymore on latest ASUS BIOS. Unless I changed any of the settings wrong. Maybe this is because SOC voltage is now actually the value you set rather than the value plus extra. Edit: indeed seems to be more stable (e.g. no instant BSOD) when I raised SOC voltage from 1.25V to 1.30V. Seems like 1.25V is no longer enough. Edit: still crashes even at 1.30V.
Thank you! Using a B650E-E Rog Strix board, and even in BIOS it would just freeze. I managed to switch the voltages to 1.30v,(which is max) and so far it seems stable. Gonna have to test it out with regular use.
@@AliBabah91 unfortunately after not too long it crashed again, so I'm just using expo now. Might be better for you depending on your motherboard, memory kit, etc.

I wish Buildzoid would make a small PSA about power down mode. Memory context restore MUST be disabled if you disable power down mode, or you will bluescreen. You will bluescreen so bad that's if you manage to get into windows, wonder why, and think it's these memory timings. No, it's power down mode. Go ahead and disable power down mode, but ALSO DISABLE MEMORY CONTEXT RESTORE. MCR on auto, or enabled along with power down mode disabled will cause massive issues. You sacrifice slightly faster boot times, in exchange for ditching power down mode which slightly harms memory latency performance. Please like this post get it to the top, save folks a lot of headache.

This mostly worked for me. Wouldn't boot into Windows. I added 25 to each tRFC to get it to boot. Now, to test for stability. Currently at 6400 MT/s and 2133 FCLK.
@@lsik231l Hey, I think there's a small misunderstanding. The unit of timings are actually clocks - so the faster your frequency is, the looser your timings have to be. That's because the RAM still needs the same actual time for certain operations (a timing is basically how many cycles a certain operation needs)
So if you have Hynix and it's rated for higher speeds than shown in this video (6000MHz), you're gonna have to loosen timings. You may be stable on the timings you have set right now, but I'd really test that with proper stress tests (TM5, HCI Memtest, Karhu (paid), y-cruncher, prime95 Large, OCCT CPU+Ram Large, etc)
Ran these settings for 14ish months, can confirm they were rock solid. Only checking back in because I had to swap my mobo for unrelated reasons!
This worked for me. The hardware unboxed video testing these timings vs expo/xmp led me here. Thanks for making it easy to follow!
I confirmed I have hynix memory in Thaiphoon Burner but these settings didnt work at all, when it rebooted after saving just the dram LED comes on. Any ideas?
@andreas6870 I swapped cpus for another 7800x3d and it works flawless now. I believe the first cpu had a weak memory controller.
@andreas6870 Glad that worked for you seems to be alot of factors effecting ram speed then
For the longest time I tried to enable EXPO on this same motherboard without luck. Crashes, bios updates, BSOD, etc. I got a different ram kit (which happens to be the same one you got). I used THE EXACT SAME settings you have and no issues since then! I really appreciate it! I have another build but that one has Samsung die which would be amazing if you could “build” expo settings for it since it is the exact same issue I had but on that build. Again, thanks!
I really appreciate the videos where you show timings that should be valid for a particular memory module/manufacturer. I used your videos applicable for 3200 CL14 b-die for ryzen to OC to decent timings 3800MHz cl16 and it worked fantastic.
I'm sure many people need this content right now! Well done.
Thank you Buildzoid, I appreciate your content very much! Your hours of time and effort is more than we're worthy of.
We are not worthy, oh great one.
Yes, many thanks for giving some insight in stable timings for an former Intel user. Much appreciated.
Hi Buildzoid, love the thorough testing of how to get our Hynix RAM in order. Thanks so much, normally never comment but frankly you more than deserve the like + comment engagement for the algorithm.
Appreciate the video.
The reason why 2033FCLK is faster is because the memory is implicitly run at 6098-6100MHz. The Agesa BIOS versions appear to do this. If we set the FCLK to 1 step higher than the MCLK/1.5, then it'll advance the MCLK to match. This also occurs at 6200MHz with a 2100FCLK, which will result in a 3150 MCLK. We can see this effect if we use ZenTimings. This gives precisely a 2:3 ratio between the FCLK and the MCLK. Yes, while that's not an even ratio, it does mean though that for every 3Hz on the MCLK, that the FCLK is directly in sync at that precise moment leading to improved behavior. A better ratio would be to have FCLK be half of MCLK, but since the MCLK speed is generally limited to 3200MHz at most, the reduction in FCLK speed harms more than it helps. Maybe Zen 5 will be about to hit 4000MHz MCLK, and if so, that'll be the next "sweet spot".
For whatever reason, 2033 is a good bit slower than "AUTO" for me on the MSI MPG B650I mITX board. All of these timings worked for me other than tREFI (MSI does not list it on this board yet iirc).
@@nextjin how do you test?
@@nextjin Also, would these timings improve gaming?
@@jesusraya4484 what do you mean how do I test? It would crash at 2033 on my mobo. And yes it will improve frame rates. Way less so if you have a X3D chip though.
my computer crashes whenever i disable power down mode. should i just keep it at auto?
Thanks so much for this! I am new to AMD and resources like yours have been instrumental in helping me make the most of the hardware!
These timings worked really well for my budget hynix based sticks. Saw a signifigant improvement in Aida memory benchmark, and so far stable even with my DRAM voltages set at 1.25v which is what my kit is rated for at xmp (my ram doesn't have expo support) , Thanks a bunch!
oh thats fun to hear i think im gonna try this out too!
I was able to replicate the exact sub timings on my 13900K system with a G.Skill 5600 CL30 kit (that I tuned to CL28) and it passed all my tests. Reduced the memory latency in AIDA from 67ns to ~61ns. All without touching any voltages. Neat.
If I’m trying to get 7400cl34 down to cl 32 how should I go about it
Thanks Buildzoid, I followed these settings for my ADATA 64GB XPG Lancer RGB 6000MHz DDR5 on a Gigabyte B650 Aorus Elite X motherboard with a 7800X3D. My system seems stable with VSOC of 1.2V (was too scared to bump it up higher due to exploding CPUs) and VDD of 1.35 (as per EXPO profile).
One thing I found different is that for my Tras, the lowest value I could set was 76. I had no option to set it to 28.
what kinda performance gains did you get? i have the sameeee cpu and mobo
Mine is 30
Thank you very much for this. This solved my CL30 6000 hynix woes. The expo profile was simply not working on my MSI B650I Edge Wifi and this guide fixed it in one go. So far very stable running memtest. What a lifesaver!
As always i appreciate your content and im happy to see you seem fine after the break :).
The reason why 6000 2033 works better is because the A+D agesa has a bug where on some frequencies combinations the actual frequency increases eg: 6000+2033 = 6100 (3050 uclk)
6200+2100= 3150 uclk, 6200+2133= 3200 uclk, 6400+2167 = 3250 uclk.
right now I'm able to run 6200+2100 ( which due to the bug with 6200+2100 runs at 6300) with 1.4v on memory and 1.25v on soc, testing to see if I can go lower, 6400 booted but kinda unstable not sure it's vsoc or primaries or rtts tho
oh great,i just noticed he is using agesa 1003, so yes,you are right, that also means that the info about 2033 fclk in this video is already outdated because that bug is fixed in 1004.
@@c.chepre8452 ohhh that explains why i saw basically 0 difference going to 2033...

I'm not knowledgable enough to see how 1004 would change it. Asrock didn't release 1004 (yet?).
Did you manage to run 6200 + 2100 stable? For me it crashes in games.
My dumbass bought XMP ram on my AMD build, and this guide got me through hours of issues with ram timings. 10 years since my last build. Got it running at 6200! Thank you.
Be carefull setting Power Down DISABLE on certain motherboards. Here on B650 Tomahawk with M-Die ram kit if you set PD off and CMR on it will lead in bsods and boot corruption, so POWERDOWN need to be ON if Context Memory Restore is ON. If you corrupt boot with bsod at startup do this: tap F1, then Prompt Command and type exactly this: BOOTREC /FIXMBR, press enter, then type: BOOTSECT /NT60 SYS, press enter, then type: BOOTREC /FIXBOOT, press enter, type EXIT, enter and reboot. Now boot is fixed and windows will start. Thanks me later :) This should be put in description
So what I shoud done? I shoud off PD or dont touch it?
I have alresy off CMR
@@siebakk827 With CMR off it can be disabled, but some ram/mobo combo still don't like PD off however
My system crash like crazy with PD ON if I'm using Buildzoid timings but when I'm using EXPO then I can turn it ON. I don't know what's better EXPO with MCR ON or Buildzoid timings with MCR OFF. The difference in boot time is big 16s vs 56s
Are y’all on latest bios?
Thank you, thank you, thank you!! This is the second time using these timings whenever Expo is not running stable. With these settings, and using the EXPO timing, with G.Skill 64GB (2x32) 6000 CL32 on a Tuf B650 plus-wifi, I am having no more crashing, or boot errors. Last time I had to use these eventually BIOS updates came out and I was able to use the Expo settings with no adjustments, but until then, yours run flawless as is.. and they are fast!
This video probably saved me and and my house from catching fire, I'm glad I instantly applied these settings first thing first back when I bought my 7800x3d, it was before all the reports even came out. Thank you.
I've been waiting so long for this. I have that exact mobo and F5-6000J3238F16GX2-TZ5N ram kit. Running all your settings but primaries are a hair tighter.
Pretty straightforward, even easier since we pretty much can use same settings as shown. About a 9% faster ram for me and my latency went from 85ns to 70ns. Thank you!
I'm getting about 67ns. I guess that's good since you were getting 85+ before.

I wish I could like a video 100 times. I was having a lot of problems with my new 7950X3D/GSkill Trident Z5 2x16GB build. The PC would reboot randomly when doing simple tasks like browsing the web or using light programs, would also error and reboot within seconds every time I started the OCCT memory test. I was certain either the CPU or RAM was defective and was almost at the point of returning one of them.
Took me some good 3 weeks to find a post that said they had a problem very similar to mine and this video fixed it. I *think* the problem all along was that I enabled EXPO as soon as I got the machine built, but for some reason the preset didn't change the voltages to be able to handle 6000mhz. I have an MSI board and the VDDIO voltage is grayed out and cannot be changed without also changing the DRAM voltage manually. I think the EXPO preset didn't account for that.
Anyway, thank you so much, I don't even care about overclocking RAM, I'm just glad the PC is working smoothly now.

Like so many others here, I can't thank you enough.
I've had nothing but issues with this new rig. Gifted my old one to my eldest. It was rock solid. Built pretty much the same rig (same mobo as this video), but went with a 7950x3d and 64gb rather than the 7800x3d and 32gb I used to have.
Boy, I had buyers remorse. I even swapped the ram at one point. Trying to isolate the BSOD's... That did help. Was still getting unsafe shutdowns. That was actually a Windows issue (Fast Boot.... Giving driver errors)
I've swapped PSU's (my son has the same), trying to isolate the problems.
I was ready to send back the mobo...
So I thought, well, why not give your timings a go. For whatever reason, EXPO on my rig was giving more voltage than your guide!! Not unsafe, but higher than what you recommended.
I dropped my RAM from 6000 to 5600, to get better CAS, and other primary timings.
My Cinebench 2024 went from 2024 (I couldn't get it higher!!), to 2132!!! On lower voltages, lower temps, a higher UCLK, and a Lower MT/s
I have absolutely no idea what any of those numbers actually mean. Hence why myself, and so many others, rely on EXPO to them for us.
And to be frank with you, I don't really want to learn what they mean, other than the basics, and that they work, and have improved my performance whilst lowering my power draw and temps...
Why aren't you the ones setting the EXPO settings? Like seriously. These companies should be employing you as a consultant.

Disabling Power Down with Memory Context Restore on or auto causes BSODs
Good lord I wish I found this comment earlier!!!!!
Kept getting blue screen of death on 2nd boot!
Copied these exact settings for a cheap Team Group 5600 CL32 kit and it works perfectly. I was even able to get it to run at 6000 without changing any of the primary timings.
FYI, disabling Power Down Mode made my system incredibly unstable - would blue screen on/just after boot over half the time, and even freeze in bios frequently. Took a while to narrow it down, but that seems to be it

Just built my first computer from scratch and I bought RAM without EXPO and this explained a lot for manually inputing the timings. Thank you
on my A-die Kit, I can get 4-4 TRRD's working and 8RTP.
The main thing is you have to raise the SOC voltage ever so slightly and it will start working.
I had to set mine to 1.22 to get it stable.
If i tried 1.2 I could only get 4-8 stable,
Ran Y-cruncher/superpi/linpack/occt for many hours just to verify that 4-4 was stable.
Figured I would share since I had the same issue with My TRRDL/RTP not cooperating.
I've tested this kit even with 1.4V SOC and it just doesn't do tRRDL lower than 8. It also needs loose tRRDL on intel.
My RRDSCL can't boot with 4, the lowest is 5 but it's unstable. I'm running SOC 1.35v, any idea how to run 4?
@@nguyendinh2052 for me voltages really were the main key. Cause just like you my A-Die at certain voltages didn’t cooperate at all with anything below 4-7.

Buildzoid!!! Your guide saved my 7800X3D from burning out. So happens I was using the same SK Hynix Intel RAM as this guide. And setting the Mem controller voltage to 1.35 prevents the burnouts from happening
Better waiting for official statements about this shitshow. I completed my build 4 days ago and had to update bios 3 times since...Btw, using this memory timing is stable according to many users including me. Still, haven't heard any of them talking about their Mobo and CPU being burned, mostly from EXPO users.
In light of the memory voltages being the rumored problem child for X3D CPUs dying, do you still feel good about the 1.25V here? And what of the other voltages? I think that's lower than what it's rumored to go if you leave it on EXPO.
Its scary for sure ;/ Makes me never turn Expo... or until they fix it.
They forced the number down to 1.30 in the latest bios. So I think 1.25 is more than just safe. Maybe anything below 1.4 is safe, idk.
Can confim that i can replicate this exact settings using ADATA Lancer AX5U6000C3032G-DCLARWH (32x2Kit, 6000Mhz, Hynix A Die), everything is working great as well, i don't even need to change DRAM Voltage. Thanks a bunch Buildzoid!

But by changing the Timings I at least can have both EXPO and Memory Context Restore enabled without any issues or blue screens like before. Also I have seen people on Reddit saying they got their system to boot instantly by changing the timings to 36-36-36-72. Unfortunately didn't work for me.
Thanks for the video. I applied exactly same setting for my pc, working flawlessly so far. My setup is like this : 7800x3d, Asus ROG STRIX X670E-E BIOS 1416, Kingston DDR5 32GB(2x16GB) 6000MHz CL40
Thank you ! Your settings also work with 4x16GB of G.skill F5-6000J3038F16GX2
Awesome improvement over EXPO profile 👍
Are you running this kit on AMD?
@@ksenchy yes, on a Strix X670E-E and a 7900X
Had to drop to 5800MHz though, as I was getting errors with 4 sticks. But it is stable with 2 DIMMs at 6000
That's what I was going to ask you, I'm thinking of moving AM5 and going 4x16GB and I can't get any serious answers if 6000 will be stable with 4 sticks. All these TH-camrs and media outlets only test 2 sticks 💩
There are Corsair 2x32GB at 6000MT/s sticks but oh boy CL40 sounds horrible.
I'm not buying any other brand as no other has hardware RGB profile support.
I don't know, wait another generation so AMD improves DDR5 memory controllers in next generation or win a silicon lottery so I can run 6000 stable.
@@5pyR17US I have the exact same setup than you, but I can't get EXPO working on mine for nothing with 4 modules (it works with 2). Did you only have to drop frequency to 5800MHz to make it work or there was something else? I also wonder what your BIOS version is.
Any help is greatly appreciated. I can't get my ram to get past 3600, which is a bummer.
@@icarus33 1416 is the latest bios allowing my RAM to remain stable with 4 sticks at 6000.
After this one it was impossible, no matter which settings I tried. I ended up buying 2x32Gb instead and since then my setup is fully stable with these timings at 6000MHz
Was having issues with the EXPO profiles. So far so good with these timings. Thanks!
With my 7700x, Asrock b650e Pg Riptide and Hynix A-die (2x16) I've spent several hours to optimize timings one by one and I came up with the same values. In my setup the FCLK is stable at 2100 and Trdrw can easily go down at 14. Unfortunately at the moment Asrock bios doesn't allow to modify Trefi.
Update your bios, tREFI and GDM can be screwed with now.
So fantastic your video, you saved my life, I tried to upgrade my memory with 2 additional 16Gb DD5 Lexar Ares, identical to the first 2 I already had and there was no way to run this memory at decent settings. I was worried to have to accept much lower speed to increase my memory. I know that 4 modules configuration is harder to get to work with XMP, but your settings allowed me to run then at 5600 Mz instead of 6400 but with tighter primary timings resulting in identical if not faster results than with only 2 modules, great job !
Used the exact timings on my rig and got a noticeable performance boost over the regular XMP.

[First time PC builder] Glad I came across this video. Couldn't get past 5600Mhz with default expo settings, not sure what was wrong there. But with these timings 6000 seems to be running smoothly with ryzen 7900x and asus x670e-a.
After hearing that it is very difficult to deal with ddr5, I did not expect that it would be so easy. Thanks for that. can you share 7950x settings for Asus motherboard for the safe and better multi-core performance?
Just come through the video and copy, thats what I did. I have a 7950x with an Asus x670 pro wifi and the settings worked fine.
My PC with EXPO on was freezing after some minutes on windows and restarting without a blue screen, I set these timings and for a good few hours it still didn't happen again. I have a ryzen 5 7600 with teamgroup 2x16gb 6000 cl30. Thank you very much for sharing this information and allowing many people to solve their problem!
Great videos, thank you so much for this easy to follow instructions and making DDR5 tuning easy. Geekbench will immediately show the benefits of low latency in their results. It worked perfectly in my 7900X system using Corsair (Hynix) DDR5. Great performance and stability!! 💪💪💪
(OCCT doesn’t seem to like it though… weird program)
Hi sphaera, I have a similar system to you. Do you mind telling me what Corsair memory you're using? I have the vengeance 5600 c36 and want to check before I implement the settings.
Good stuff Buildzoid! Been looking forward to this!
Another similar video with the latest BIOS would be nice.
Did you find it any video ?
Amazing improvements with these settings! I'm running memory tests now.
Just used these timings on a pair of Team Group Delta RGB 16GBx2 and all is well. OS is snappier and cranked out more fps in my games on a 7700X
I have the same sticks, would it work ? I’m on 7400mhz cl34 tho. I’m trying to get the cast latency to cl32 for a 1 & a half minute reduction.
Thank you so much for these, I'm using four sticks since I didn't know about the issues before hand and was having immense trouble getting my system stable at anything past 5400MHz, with these settings so far it's been stable at 6000MHz running tests for an hour or so, before was getting memory errors within few minutes.
E: Seems my system is stable at 6200MHz memory speed with these timings, absolutely magical.
Very interesting, with your settings I'm getting about the same bandwidth as I was able to get with 6200 and 2066 fclk but slightly lower latency with less voltage. Good ram diet.
Whats your bandwith values read/write, copy ?
thank you man. I've heard mentions of you all over the internet and then I found you here... fingers crossed........ this computer was way too expensive to just have it run okay-ish most of the time... ya kno
Thank you for your time and effort! I would love to see timing setups for Samsung memory. EXPO is not really working for me with Corsair's CMK32GX5M2D6000Z36 Kit, on my ROG CROSSHAIR X670E HERO mb.
Bit late with the reply but I had the exact same issue with the same kit, swapped it for G.Skill F5-6000J3038F16GX2-TZ5NR as i was in the returns window and so far it's been great
@@MoosePlus Thank you for the reply! What motherboard are you using?
Thank you for taking the time to do this Video. I have used your guide and it has worked perfect. Great Video. Cheers
Have any of these recommended settings changed with the new AGESA? Curious to know how it has affected them and would love to see a new update video on it.
Thanks for this Buildzoid. I ended up here mainly because three different memory kits wouldn't hit their rated speeds. I had issues with the Samsung kit I had hitting anything over 4800, let alone the EXPO profile. No matter which BIOS I've tried no kit I've had will do anything over 5800, which makes me feel like it's probably my luck in the silicon lottery on my 7950X. Regardless, this helped me tighten the timings if nothing else. EXPO results in unstable memory for me.
Very nice timings and easy to run. I've tried to lower the voltages and I am able to run them at 1.1v for SOC Voltage, chances are that the MC voltage can be lowered as well.
Nice. You're right, VDDIO/MC and VDDQ should both work without issue at 1.25.
My understanding about SOC is that the amount you're able to lower it varies by individual hardware. Most should be able to do 1.20, some (like yours) can do 1.15 or 1.10.
@@subaction I'm doing 1.1v SOC and 1.2v VDDIO/MC. But for the ram sticks themselves I can't go lower than 1.325v without Y-Cruncher giving errors after some hours.
@@Zetzun Sounds right. The RAM doesn't mind and isn't hurt at all by 1.35 or 1.4v. I'd say your setup is working ideally

Now timings are much tighter and it runs smoothly
do one of these for dual rank!
Buildzoid, you are thé man. Thank you mate for all of your content i love so much.
These settings also work for 6000MHz 2x32gb which are dual rank. Only thing different i did was oc to 6200mhz and dropped tcl 30, trp&trcd 37. This was on a 7800x3d oc'ed to + 5% and vsoc @ 1.26 in bios and under heavy load doest go over 1.305v in occt but aida64 has not exceeding 1.296v.
Are you running Gskill memory?
Thanks a lot! EXPO was giving me random crashes so really needed a fix and this seems to have worked.
Couldn't take the long boot times. Set memory context restore and power down mode to enabled again. Fixed boot times (about 35s). And latency only went from 61ns to 63ns.
👍Thank you ASUS for supporting Buildzoid!
Any change for revisiting these? Asus X670E Plus and BIOS 1616 these no longer work :( No issues on older BIOS versions, on 1414 worked even with 1.25SOC.
You sir are an absolute legend, I was ready to return my kit but said it was worth a shot to try your settings. Save and restart and guess what it booted up right away. A blessings from the lord 😂😂 Thank you, life saver.
This will be useful soon! What do you think of this board?
It's TERRIBLE at DDR 5 training.
That's my take.
My first born's name will be Buildzoid, respect to your wisdom and work!! Thanks smm
Can confirm asrock riptide + tcreate runs these settings flawlessly. Saw massive improvements over stock expo of 6000 and cl30. Subtimings is the key, it goes beyond benchmarks... I can feel the snappiness opening programs and basically any task. I have a 7800x3d also, and collectively I feel the change.
Used the gskill 6600mhz cl34 1.4v kit as an a die source on my msi x670e carbon. It performs amazingly. Oddly though, my board would not let me set tras to 28. For whatever reason the minimum value the board would let me set was 30. Still seems to work just fine though.

@@ActuallyHardcoreOverclocking
Hi, I copied your settings and got an overckock that seemed stable on Windows 11 because the computer wouldn't restart. However, when playing a game like halo infinite or battkefield V for 5 minutes, the game ends up closing. With other types of overclock the computer was restarted, which I consider more unstable. How can I keep similar values and prevent the games from crashing? I don't know what value to start changing or raising again or what you can advise me to try to find stability in games.
Currently I tried other settings with my same RAM from a web and other secondary values and I got improvement, but without a doubt yours was the best. of 70 ns with the Expo value of the latency ram at 56.7 ns, a beast. The reading and writing speed also increased by about 400 points. In games, the performance improvement is noticeable a lot, especially in CPU-dependent games, I made comparisons and the average, low and maximum fps increased a lot. For this reason I do not want to give up your magnificent overclock profile, and for this I want you to advise me what values or value I should go up little by little to find my point of stability.
My ram is a Flare X 6000 CL32 32-38-38-96, and the primary values that I set along with your overclock were 28-36-36-28. The overclock that I was trying previously was the one in the following link: www.techpowerup.com/review/g-skill-flare-x5-ddr5-6000-cl32-amd-2x-16-gb/8.html which was stable if I applied only the primary values, but when applying the secondary ones the pc ended up restarting at some point.
@@SightlyJesterI think he said to use the primary timings that came with the RAM. So 32-38-38. You are lowering those timings quite a bit
Hardware unboxed will be releasing a video on this shortly. It's already available on floatplane. Long story short, these can make a 5200 cl30 kit perform similar to a 6000 cl30 running expo.
Just achieved your exact settings on a totally different kit, albeit with Hynix (A) memory.
T-Create Expert 64GB (32x2) 6400 dual-rank on a 7500F. Even the primary timings worked (though other's mileage will vary).
Tested with Y-cruncher only, then played FC5 for a couple hours.
Thanks a lot!
Thank you so much for this! I used your settings on my G.SKILL Trident Z5 Neo DDR5 6000 64gb kit and went from read rate of 70,238 MB/s to 84,750 MB/s; and latency of 69.1ns to 59.4ns.
One question I have is on my Asus x670e Hero MB, the CPU VDDIO/MC voltage, when I set to 1.35000 V, it changes the value to something like ~1.35663V. Does this matter?
no, that doesn't matter, it's normal

After searching the web high and low I am back where I started my journey. Been lookin' everywhere and anywhere on why my system was still crashing after hours of stable stability testing. Lo and behold Buildzoid tells you right at the beginning of this vid that the GPU's been the one that's been cooking my DDR5 ram kit and just hard shuts down my PC. Stability test that always came back stable. Not knowing usually the GPU doesn't get stress tested in these tests and therefore doesn't cook my RAM kit. But after an hour or hrs gaming my PC just been crashing. I played with voltage, temps, limits, underclocking/overclocking, nothing made a diff. But here Buildzoid just tells straight up why it happens. Damn it all those wasted hrs. Didn't even think of the GPU that could be the culprit. Ty Buildzoid 🙏forever in ur depth. K now I gotta figure out a way on how I can prevent or reduce the cookin' of my RAM kit.

Got a minor problem when applying this with 5600Mhz Kingston Fury 2x32GB on Ryzen 7900 non-x. Blips of green or white happens inside Windows 11 once in a while. I will investigate, do you have any idea why it could be? Seems like something interacts with the iGPU (not running GPU). Would the SOC voltage have to be even higher?
Thanks for another amazing video! Favorite overclocker!👍
EDIT: tRAS was the solution! Increase tRAS to 36

Just to add my experience in case it helps some lost soul: Kingston Fury Beast 6000Mhz 2x16GB, Windows 10, Ryzen 7600x, screen would flicker or flash black when on igpu. tRAS is the solution.

Great and useful vid BZ, appreciate it!
Any thoughts on GDM setting (ADDR_CMD_Mode for ASUS). I've read that disabling it (setting to BUF) can improve latency?
P.S.: Would be awesome to get a vid on how to best push m-die to 6200/6400 with emphasis on MC, IF and CPU voltages.
At least on zen 3 it was know to improve performance because GDM does some strange interactions with command rate, so even if you had 1T on the command rate, in reality it was performing like 2t (or worse) if the GDM was enabled

@@Kestrelms i can back him up GDM ON does indeed have some horrible flaws when you overtight some timings like tRRDL 4 instead of 6 , tWTRL 8 instead of 10 and tRDWR / tWRRD ratio if you use lower tCWL than tCL. might be just a dual ranked issue. in my experience i would use a lower frequency with gdm off than a higher one with gdm on.
might be a specific motherboard / ram issue, might be something else but the issue is there.
Edit: GDM ON feels like a fake stable settings on some rare situation, doesn't throw errors but gives significant worse result than 2t.. not to mention 1t pure. For some reason most overclockers and AMD recommend GDM ON for Dual Rank kits, based on my experience i don't.
The content is incredible. Thank you for the video, that is exactly what I was looking for
Seems not to be working anymore on latest ASUS BIOS. Unless I changed any of the settings wrong. Maybe this is because SOC voltage is now actually the value you set rather than the value plus extra.
Edit: indeed seems to be more stable (e.g. no instant BSOD) when I raised SOC voltage from 1.25V to 1.30V. Seems like 1.25V is no longer enough.
Edit: still crashes even at 1.30V.
