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

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,

Cheers and happy New Year everyone.
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
and we are waiting for the new bios update...
Good luck with your Mortar purchase! I hope that it will work out.
