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 itI 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 22.214.171.124 3 days ago for one or two mobos. Any information about Tomahawk x570?
Did you try to lower your voltagem a bit? Lets say 1,25v for your 43 multiplier?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
Hello! I registered here just to say thank you for sharing this with the community.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.
Mine is 5950X, it is said that it boosts up to 4.9Ghz single core. 5800X is 4.7Ghz.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.
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...It's very frustrating that AMD nor anyone else, even reviewers, don't say anything about this.
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 is not able to boost past 4300MHz (instead of 4600MHz) with the latest non-beta BIOS. I am hoping with the 126.96.36.199 agesa based bios for mortar and the suggested tweaks in this thread that I can get some better results. The latest beta BIOS versions 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.
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.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...
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.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.
Cheers from Lusitania ;-)
My BIOS shows the same.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.
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
