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.

*Summary* (so you and I don't have to skip through the video anymore :D): SoC Voltage: 1.25V MEM_VDD: 1.35V CPU_VDDIO: 1.35V MEM_VDDQ: 1.35V tCL/tRCD/tRP: whatever your kit says in its EXPO/XMP profile tRAS: 28 tRC: 68 tWR: 48 Refresh Interval (also called tREFI): 50000 tRFC1/tRFC: 500 tRFC2: 400 tRFCsb: 300 tRTP: 12 tRRDL: 8 tRRDS: 4 tFAW: 20 tWTRL: 16 tWTRS: 6 tRDRDSCL: 4 tRDRDSC: 1 tWRWRSCL: 4 tWRWRSC: 1 tWRRD: 2 tRDWR: 16 UCLK DIV1 Mode: UCLK=MEMCLK Power Down Enable: Disabled (also disable "Memory Context Restore" in order to not get BSOD, maybe it will get fixed someday) FCLK: 2033MHz (not recommended anymore, was due to a bug also forcing 6100 mem-freq when setting this)

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!

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.

I'm sure many people need this content right now! Well done.

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.

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!

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!

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

Was having issues with the EXPO profiles. So far so good with these timings. Thanks!

This worked for me. The hardware unboxed video testing these timings vs expo/xmp led me here. Thanks for making it easy to follow!

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!

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.

Good stuff Buildzoid! Been looking forward to this!

Thank you Buildzoid, I appreciate your content very much! Your hours of time and effort is more than we're worthy of.

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.

Thank you for taking the time to do this Video. I have used your guide and it has worked perfect. Great Video. Cheers

Great video, thanks for doing all this research and testing for us. It's extraordinarily helpful

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.

Thanks mate, appreciate your work, I learn something new and also useful from each video!

Thanks A LOT for this video, im just about to buy a new system and was looking for something along these lines for a while!

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)

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.

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!

Amazing improvements with these settings! I'm running memory tests now.

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.

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!

The content is incredible. Thank you for the video, that is exactly what I was looking for

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

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.

Buildzoid, you are thé man. Thank you mate for all of your content i love so much.

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.

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".

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

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

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

I think finity fabric is a much more fitting name. I'm so happy to see a new mem oc video. Please do one on intel 13th gen next time.

Thanks a lot! EXPO was giving me random crashes so really needed a fix and this seems to have worked.

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!

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.

I was so scared to mess with ram settings, after watching a few od your vids i decided to give it a shot. Explained perfectly, i have been runing cl 30 36 36 28 (everything else copied like in this vid) at 6000mhz with no issues, 1.35v for a few days now. I have a Kingston Renegade kit 6000mhz cl32. (KF560C32RSK2-32). Thank you so much, im so proud i finaly did it 😅. 66.4 NS Latency on AIDA64 Test. And my cpu score increased almost by a 1000 points on Timespy. And games like CS2 and Warzone run so much better, a lot better 1% lows and stutter wise a lot smoother. Max ram temp is 48c when gaming.

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!

Brilliant, worked flawlessly, thanks much, amazing how much "slop" there is in stock timings.

This is precisely what I have needed. Thank you, I even have the same motherboard.

I'm still on ddr4 but enjoy these videos

I was waiting for such a video! I have a B650E-E and 2x32 Hynix at 6200. If I set tRAS below ~40, I get artifacts on the iGPU.

Absolutely thankful for this video and for your efforts.

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

Can't wait to see how fast DDR5 gets by the time I'm ready to move to AM5

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!!

This timings worked like a charm in my kit, thanks you so much for your effort and ramblings haha BTW i have the 2x16 Teamgroup Vulcan Alpha 6000 38-38-38-78 1.25v but at 1.35 it runs great at 30-36-36 + your timings

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!

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.

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.

Just wanted to add my voice to the list of people who this video really helped out. I just built a new system with a 7800X3D and a 4090, and I bought a 6600mhz Corsair kit to pair with it. Well, as soon as I enabled EXPO, got tons of instability and crashes (this is my first AMD CPU, I figured EXPO was just like XMP where you just set and forget and things Just Work. Fool.) Was feeling like I was doomed to stay at stock speeds until I found this video. Did three different memory tests after plugging in your settings (had to bring her down to 6000mhz but that's fine) and seems stable, zero errors or crashes thus far. Thank you so much for making this!

cool i cant even get into my bios anymore after following these settings and now i have to figure out more, thanks

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

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.

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.

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 !

Disabling Power Down with Memory Context Restore on or auto causes BSODs

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.

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

Thanks for doing this, it's much appreciated.

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 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

Thank you ! Your settings also work with 4x16GB of G.skill F5-6000J3038F16GX2 Awesome improvement over EXPO profile 👍

YES! thank you so much! Going to make a coffee and dig in.

Exactly what I needed! Thank you!

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.

Set this with slightly lower voltages and it still runs flawlessly after bunch of tests

Hey BZ ... this is great, can't wait to try it out. I've always been kinda timid about tweaking all these settings, but after following your vids for a while (even though most of it flies way over my head..😅) I feel more confident (having the exact sticks your working with doesn't hurt either...lol). much thanks for sharing your knowledge and experience with those of us in MEM TWEAK 101 (well...me at least on this one). 🖖🏻☮👌🏻 DT

Worked great, zero fuss! Thank you!

This will be useful soon! What do you think of this board?

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.

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.

Excellent video. Thank you 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.

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.

Dropped my latency from 72ns to 61ns. Well done, Buildzoid!

I've learned so much from watching you're videos!

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!

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.

Huge 13% more CPU frames. I followed everything, but I already had the 3 primary timings. Thank you.

Thanks, really appreciated, works OK on G.Skill Z5.

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.

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 very much for this information. It all works great with my 2x48GB 6000MHzC32 kit :-)

Happy days. Love these.

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?

Did this with some 36-38-38-96 G.Skill DDR5 6000 sticks, a 7950x3d, and Asus ROG B650e-I motherboard. Works perfectly.

[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.

Thx a lot for ur sharing! Got corsair Expo 6000 cl30-36-36-76 and with ur settings now around 10 percent faster

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

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.

I haven't done any stability testing, but these settings boot no problem for me. I have an x670e ASRock Taichi motherboard. The only setting I couldn't find is refresh interval. I looked all over the BIOS and couldn't find it. I've always used ASUS boards in the past and this is my first ASRock board, and comparing the two, ASUS seems to have the better BIOS, but this board has been incredibly stable. It boots with every overclock and undervolt setting I've thrown at it. Thanks for the information.

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.
