I have 5900x and f...n reboot problem for 3 weeks.
Multipler 43, vcore 1.3V - stable
Any information about bios update?
It seems that MSI relased 1.1.9.0 3 days ago for one or two mobos. Any information about Tomahawk x570?

Hi🙂 Following the guide in this thread helped me alot, no random reboot in days. It's stupid that we have to have all this hazzle, but i think i read somewhere that hopefully there will be a new bios update in january. Can't remember the source, so don't vager your life on it

But there is one big problem for me
With everything set to auto my CPU temps under high load are around 72 degrees average with 78 at peak
With fixed cores and voltages my average CPU temp is around 80 with peaks around 90

Did you try to lower your voltagem a bit? Lets say 1,25v for your 43 multiplier?

I am not at home thus o cant take pictures of the BIOS. But settings are Simple:
-Global c states DISABLE
-CPU multiplier 45.55
-Vcore OVERRIDE 1.25 volts
-Vsoc OVERRIDE 1.1 volts
-Load like calibration MODE 6
-Cpb and pbo DISABLE
-XMP ON profile 2 (3600 mhz/ IF 1800 mhz)
-VRAM manual 1.35 volts

Temperatures are quite low: 30 degrees idle; 49 degrees in gaming and 64 degrees in Cinebench r20 multicore. (20 degrees room temperature.)

Never had a single crash or whea errors with these settings.
Hello! I registered here just to say thank you for sharing this with the community.
I took this as a starting point, googled some more and was finally able to resolve my problem.

So, I too had problems with my 5950X on X570 Tomahawk
BIOS update from v14 to v151 beta alone did not help
I had a lot of WHEA Cache hierarchy errors and random restarts while idling or some very minor load.
Crashes happened on both Ubuntu 20.04 and Windows 10 64bit latest updates.
I even submitted a ticket to AMD (probably should send one to MSI as well...)
Sometimes it was just absurd - load Windows, and after idling a couple of seconds at login screen, system crashed and rebooted.
Sometimes it happened while AFK, sometimes when I just used search bar in Chrome...
And never under some really heavy multicore load (cinebench, compile, even gaming...)
It was all using stock/auto BIOS settings + XMP enabled.

So what I did to finally make my system stable:

1. Updated BIOS to the latest v151 beta
2.
Disabled Global C State
it bumped my idle power consumption a bit
3. Set Curve Optimizer to +2 all core
it is said that you might need to try something between 2 and 8 or 10
I guess it depends on chip quality / luck / planets alignment
in my case, I might be a lucky one to get away with only +2, so very minor overvoltage for getting stock settings work lol.

The rest is auto, XMP is enabled, memory is G.Skill Ripjaws V 64Gb Kit 4x16Gb 3600 CL16 working as it should.
Seems to be stable now! With stock settings, so it is 3800Mhz multicore 4900Mhz single core.
At least for the last two days...

My take:
- CPU is from mediocre to bad batch, i.e. requires a bit more voltage to function properly
- auto voltage problems with "factory" overclocking (all these CPB, PBO), especially for peak overvoltage to reach 4900-4950 clock single core
- power saving features while switching to peak voltages do not play nice altogether???

PPL say that in January we will have new BIOS with updated AGESA (base AMD firmware) 1.1.9.0 that will be like a magical mystery cure for all our BIOS troubles.
It is already released for B550 https://www.reddit.com/r/MSI_Gaming/comments/kiro7r However, I have no idea why it is not released on target Zen3 platform yet ???

Lastly, it was an insane frustration and enormous amount of reading and learning just to narrow down the problem to make these stock settings work.
I've spent a couple of days reading probably every single WHEA thread that exists (Overclock net, AMD, MSI, Reddit, Linus tech tips forums).
I was afraid that I will have to RMA the CPU, and it is a very complicated process. But a lot of PPL do that!
Not to mention the supply shortages, the second CPU could probably be the same and I need this PC for work...

I had some static overclocking like it is mentioned in the quote as a last resort.
Luckily, it seems like I managed to get away with PBO enabled and only some minor tweaks.

Thanks again, 77griff159e02ea

Cheers and happy New Year everyone.

Thanks for sharing hypnoas156c02e2.
I think it's a matter of bios tweaks. My 5800x performs very well and cool with the settings I had mention above. Why a cpu that is ment to boost to 4.7 GHz reaches 4.9 or more? I think that if the cpu boost is limited to factory specs there were no problems. It's very frustrating that AMD nor anyone else, even reviewers, don't say anything about this.

Good luck everyone.
Happy new year!

Mine is 5950X, it is said that it boosts up to 4.9Ghz single core. 5800X is 4.7Ghz.

It's very frustrating that AMD nor anyone else, even reviewers, don't say anything about this.
that is strange indeed, I wonder why famous reviewers like Gamers nexus did not highlight that, and I know that PPL sent them DMs regarding this issue...

Hello guys,

I have the same problem with 5900x and the tomahawk WiFi.

it’s running with off set in Vcore with +0.1v but unfortunately I have 90c on CPU. Lower de FCLk and memory speed help me to stay stable.

I already tested dozen bios setups configurations with out success even after I have open an ticket on MSI..

I’m Portuguese and we have the same problem across in Europe 🤷‍♂️ and we are waiting for the new bios update...

Best Regards

Thanks to everyone for the information in this thread, particularly 77griff159e02ea. I have been having some similar struggles on a Gigabyte B550I Aorus Pro AX motherboard w/5600x. I ordered a MSI B550 Mortar to try out now as well. I don't expect any miracles, as the BIOS / AGESA seems to be the biggest issue. I am going to try out these settings if I have any problems.
My CPU (edit: on the gigabyte motherboard) is not able to boost past 4300MHz (instead of 4600MHz) with the latest non-beta BIOS. I am hoping with the 1.1.9.0 agesa based bios for mortar and the suggested tweaks in this thread that I can get some better results (edit: with the MSI board). The latest beta BIOS versions (edit: for the gigabyte motherboard) would WHEA windows without even booting. I was able to boot by setting PBO curve optimizer to +20. These BIOS versions got me to just over 4600MHz single core boost, but multicore still stuck at just under 4000. Not sure how much my gigabyte settings/experiences translates to MSI situation.

EDIT, replaced gigabyte board with Mortar. All the exact same issues. Works with older non-beta BIOS, immediate WHEA with newer 1.1.9.0 AGESA bios (7c94v154). Slow boot clock speeds all the same. AMD has approved an RMA for my CPU. Of course that won't fix the broken USB ports, which seem to still have issues even with the latest MSI bios for mortar.

Are you still getting WHEA errors with the latest BIOS 7C94v154 https://www.msi.com/Motherboard/support/MAG-B550M-MORTAR-WIFI ?
i.e. even with AGESA 1.1.9.0 ?


Edit: I am sorry, that was a misunderstanding :) Good luck with your Mortar purchase! I hope that it will work out.

I think 90ºC is to hot. The positive offset voltage stresses cpu to much. IMHO you are risking a bit. You cant run with that temperature 24/7.
My 2 cents.

Thank you , yes is to hight but this is the suggestion propose by MSI. we will leave with PBO and PCB disable until next bios update.
We hope we can have an solution on next bios update.

Salute

Yes! New bios after all this suffering :)
And I changed cpu from 5900x to 5950x
For now on latest bios there was no reboot.

I have one question.
Bios shows vcore around 1.45V al the time. I use linux, so I can't check with Ryzen master.
Is this normal? Everything on stock.
CPU under load 60-70 degrees (depends on task). I know that new Ryzens can take quite a lot, but it seems to me that it's some kind of mistake.

p.s.
CPU-X (linux cpu z alternative) shows 0.9V on idle and 1.1V under heavy load, so I believe that those values are incorrect too :)

My BIOS shows the same.
If I check Ryzen Master on Windows during some Cinebench run I can see that the actual voltage is no higher than some 1.1-1.2v.
