Ill check AIDA later , i tested CB single and im getting better results while the multi are the same.
Yes ill stick to 1867 , my RAM couldnt do stable CL14 at 1900 anyway (have to do CL15 with some timings increased) and i prefer a stable system for when im working on this system, im only trying to push its limits for fun but ofc if i find something stable i wont throw away the extra performance :)
RC and RFC are 'hard' timings. The value between no boot and 100% stable is very small. Example:
On my rev E
RC 54 no boot
RC 55 100% stable, no crashes, but many errors in TM5
RC 56 no errors

RFC 518 no boot
RFC 520 unstable
RFC 522 100% stable

RC and RFC are very important for performance, find lowest stable value for a nice boost. You probably have little gains left on RFC, but RC may do several numbers lower :)

When you post Zentimings try not to cut of the bottom part off, that has the RAM model number.

Check for WHEA errors using HWINFO64. You can probably tighten up those timings alot for better performance.

Although 5800X3D does not need fast RAM to perform it can help in some games.
If you want to run that daily you should test with TM5 25 cycles to make sure its stable else you may get data corruption or random reboots.

Run aida to see if performance is the same. Too low IOD usually doesn't affect stability, but it will reduce performance. Example on my setup:
4000 IOD aida ns:
1.04v 53.7ns
1.03v 54ns
1.02v 55-56ns
1.01v 57-59ns

100% stable, just slower.

Kerp 1867 is you get WHEA19 above :) There is little benefit above 1900 since you must raise VDD18 which can't be done on all MBs. I used to run 4000 (I never get WHEA19), but it reqUIRES 1.88V VDD18, which increases CPU-temp by 5-10C vs 1.6v VDD18 I can run at 3800. Performance with 4000 is only about 2% better so not worth it.

Ypu could try lowering WR/RTP btw: keep WR twice of RTP.
14/7
12/6
10/5
May work and give slight boost. RFC and RC may also go lower. RC maybe 52-54, RFC 520, 528 or 536. My previos rev E kit could do 522 at 3733.
Yeah , my ns was 68 69 , i went back to auto on IOD , ill play a bit with the voltages / timings later see if there are any gains there :)

I've run AIDA64 stress test for over 90 minutes with no issues I'll look at the timings.

I've re-snipped the Zen timings with the RAM part included. :)

Will Memtest / TM5

Appreciate the tips :)

What production date is your CPU? I have a 2208PGS

EDIT: and if that's WHEA error free at that IF speed you have a great chip on your hands

No errors from Memtest, MT5 or AIDA64. What does WHEA stand for? Nevermind googled it basically BSOD. None of those either. Stable as hell.

How do I find production date. CPU Z doesn't show it.

PS Not cracking my cooler to look on CPU :p

Open HWINFO while you stress testing and you can see if you get WHEAs or not.

My max stable FCLK 2022 version:

5600X 2000MHz (2/25/21)
5800X3D 1933MHz (9/28/22)
5900X 1900MHz (5/24/21)

They can all go further, sometimes much further... but they wouldn't be stable.

I won't be buying anymore AM4 CPUs unless they make something pretty kick axe, but I doubt it.

For WHEA errors you need to go into Event Viewer and look for them. You can make a custom search filter for them, too. It's the only for sure way. With HWinfo it will only show errors if they occur while it's running. In my case I could open up HWinfo and not see any errors for hours and hours. Run OCCT for an hour not see an error. So the only for sure way is to look in Event Viewer because they are always logged.

Search 'By source' 'Event sources:' and you can scroll down to WHEA-Logger.

I wouldn't be surprised if you have them. If you do you'll see Event ID 18 which is usually a voltage issue, or Event ID 19 which is Bus/Interconnect Error, which is the most common.

Thankyou am getting a lot of Event ID 19 errors. But everything runs fine. Any suggestions? Do i start bumping voltages as I have only done that to the RAM at this stage.

Mine does the same (everything works fine) and i couldnt get rid of WHEAs without going to 1867MHZ FCLK (i didnt try with unsafe high voltages) but on the good side i could OC my RAM better running CL14.

The only thing, in my experience, that fixed/helped, was to lower the IF speed. I have borderline stability at 1900 with never getting any WHEA errors while gaming but it will throw maybe 1 WHEA 19 error while running OCCT. I left it at 1900 for the longest time but was always having trouble with OCing my GPU. Kept getting Wattman crashes, weird frame dropping issues, etc. I've recently dropped down to 1866/3733MHz and so far the system seems a lot more stable!

I did try lowering VDDG IOD, and CCD and that's when I got a WHEA 18 error. Too low of vSOC voltage will also do it too but usually my system wouldn't boot in the first place.

I'd drop down to 1866 and start from there. With my chip I can do vSOC 1.018 at 1866 & 1900. The odd thing is if I get close to 1.08 I start getting weird audio issues.

Setting all voltages to normal I've gotten to 1867/3733 with no errors. Will try faster if doesn't work I'll give the ram more juice and see if I can get to cas 14/14/14

Thanks for the tips everyone. looks like my best without WHEA's is 1900/3800 ram wouldn't stay below cas16 without issues even with voltage to 1.45. So it's all running at Standard Voltages both with improved inf & ram clocks :) Pretty happy with that as it's my first time OC'ing anything in years!

This is my result with stock DOCP timing. VSOC 1.1v. VDIMM 1.4v. Frequency manual. FCLK manual . Anyone can help me to tighten timings? Im stuck at tRFC. I followed the github DDR4 OC Guide

I edited my post, i got WHEA errors with OCCT AVX2
Most people get WHEA19 above 3800, some even at 3733, but if you get rare WHEA19 it doesn't matter that much. If you get lots of them the potentially slows down your system.

No WHEA erros at 3800 (test occt avx2). Stock DOCP timing

This is my result with stock DOCP timing. VSOC 1.1v. VDIMM 1.4v. Frequency manual. FCLK manual . Anyone can help me to tighten timings? Im stuck at tRFC. I followed the github DDR4 OC Guide

Looking at your images, you've got it pretty close to the best you might be getting

Higher DRAM voltage (and cooling the RAM) might help you get lower timings by a small amount, but if you get WHEA errors, black screen crashes etc you'll need to raise VSOC instead - dont confuse DRAM errors with SoC/IF errors

SoC at 1.08v is low, my setup will boot with that but i get random crashes/errors glitches all over the place, raising it slowly reduces how often they happen til around the 1.125v mark, 1.125v to 1.15v let me go from 3600 to 3866

Run aida to see if performance is the same. Too low IOD usually doesn't affect stability, but it will reduce performance. Example on my setup:
4000 IOD aida ns:
1.04v 53.7ns
1.03v 54ns
1.02v 55-56ns
1.01v 57-59ns

100% stable, just slower.

Kerp 1867 is you get WHEA19 above :) There is little benefit above 1900 since you must raise VDD18 which can't be done on all MBs. I used to run 4000 (I never get WHEA19), but it reqUIRES 1.88V VDD18, which increases CPU-temp by 5-10C vs 1.6v VDD18 I can run at 3800. Performance with 4000 is only about 2% better so not worth it.

Ypu could try lowering WR/RTP btw: keep WR twice of RTP.

May work and give slight boost. RFC and RC may also go lower. RC maybe 52-54, RFC 520, 528 or 536. My previos rev E kit could do 522 at 3733.
Hi guys need help, I can't find VDD18 on my board, MSI Tomahawk X570, only VDD IP8 I can change value to 1.900, does any owners can tell, thx
