I disabled PBO, CPB and XMP and my PC worked with no issues with 7 days uptime. I enabled them again and it crashed when idle during the night. I see that most people who are complaning about Kernel-Power 41 errors also have lots of WHEA errors, but I don't seem to have any of those reported.

I use this PC for work so I need it to be stable. Seems to work ok when disabling all the boost functions, but I feel cheated paying so much for a new setup and having to cripple it to make it stable.

all of them are main windows components so at this point its kinda pointing as you have some corruption to your OS.

at this point you have 2 main options:
1: have you used Malware Bytes to try and see if it shows any issue there?
2: Reinstall your OS as it sounds like the OS my be very broken and it may be quicker to start over

I do not believe its the OS at fault here. I upgraded to a 3800x and 2070 super in Apr 2020, then to a 5900x and 3080 FE in Nov 2020, once I installed the 5900x, I began having all sorts of issues like everyone on here that has a 5000 series CPU. PC just randomly throws a BSOD with NTFS.SYS when idle or doing light tasks like browsing, etc. While heavy CPU, GPU load tasks such as gaming, the issues do not happen. I had 3600 RAM installed and XMP never worked, had to FCLK down to 1600Mhz and force 3200 speed, then I exchanged the RAM to 3200 and XMP enabled. Still had reboots with those settings.

Now I am using the latest beta bios (7C35v1D5) for my MB and with all settings on AUTO, I still had NTFS.SYS BSOD's, but not as many (2-3 in a 24hr period). Then I set my VCore to 1.375V and VSoc to 1.125V and disabled C-STATES and currently I had no reboots in almost 24hrs. Fingers are crossed that it will stay stable.

I agree.
My Ryzen 3900X system ran rock solid for 12 full months, until I updated to the latest non-beta BIOS from November. No hardware change.
Instantly, I got the same WHEA erros and BSODs on idle like everybody else here. Disabling XMP made it solid again, but that is no solution for long.
My Ryzen 5900X that I bought in November is still in the box, because issues seem to worsen with Ryzen 5XXX.
There is no Windows issue. We need a working BIOS.

PBO, CPB and XMP are not windows components. This is a completely new PC where I just installed Windows two weeks ago. Almost nothing is installed. It is not a Windows issue, it is MSI or AMD.

Yes, its not an OS issue at all. Currently I'm at almost 48 hrs uptime with new bios running. I have PBO, CPB, and XMP all enabled at stock settings. VCore at 1.375V and VSoc at 1.125V. No reboots so far. 🤞🤞

7C84v151(Beta version) BIOS does not seem available for download anymore. Maybe they found some bugs, or maybe they are just preparing for a new release?

I'm running: 5800x, x570 tomahawk, RTX 3080. My pc still reboots after installing latest motherboard driver.

So just yesterday, I cleared CMOS, updated BIOS. PC still reboots.

Decided to update to latest chipset driver. Both drivers are from MSI's official site. I also changed windows power plan to Balanced, not high performance.

Since making the above changes. I've been running my pc stock settings (no XMP) since this morning (9-10 hours ago). I usually have some reboots during idle and gaming. However until yesterday night, pc did not reboot.

Tested idle and cinebench benchmark. Tested gaming for around 3 hours, by loading my cyberpunk save and leaving the game on, while I'm doing other stuff. Came back expecting my lock screen, but pc did not reboot.

And it rebooted again by doing browsing tasks. FML.

Already tried the many 'bandaid solutions' provided from reddit, this forum and AMD forums. PC still reboots. Can only run somewhat stable by disabling pbo, cpb, cstate and set cpu vcore to 1.25v.

I heard the vcore voltage of a 2700x was supposed to be around 1.1 to 1.5 from different forums. My 2700X isn't overclocked, the PBO and the CPB are disabled. My Vcore voltages are around 1.070V. I have currently have a bottom rated game max 750W 80+gold cert rgb power supply, I have a near top rated NZXT 850w 80+gold power supply getting delivered in a few days. I wonder if my game max 750w power supply isn't supplying enough voltage. 20210106_204814_HDR.jpg20210106_204740_HDR.jpg Could that cause a kernel-power 41 errors and random reboots?

Hello guys, i tryed a few thing in the last days:
1° Seller send me another x570 Tomahawk Wifi in compensation for the faulty one, surprisingly BSOD again installing windows all same specs, same processor.
2° Thinking is my ryzen 3600 the problem, i tryed a different motherborad, from a friend: Asrock B450M-HDV R4.0 an 80 dollars card lol. It worked flawlessly for 5 hours 0 problems, 0 bsod.
I'm really thinking this is a bios voltage problem or something like that from amd or msi, i'm not an expert just a frustrated average user.

Can confirm I'm still having NFTS.SYS Error 41 reboots with new 7C35v1D5 beta bios. They are not as numerous (about 2 in a 24hr period), but BIOS did not fix issues. I leave my PC on during the night and at 3AM while idle, it just decides to reboot. Also doing light tasks cause the reboots. Gaming does not. Running XMP profile 1, CPB and PBO auto. Vcore 1.375V, VSoc 1.125V. If anyone has any other suggestions, let me know. Frankly I'm getting tired of this already. I just want a stable system for the $$$ I spent!

I thought I would try MSI instead of Asus. So far the only thing I like about MSI is its easier to set up nvme drive. Im about ready to go back to Asus.

Some guys say this on amazon lol:

"If you run into system instability issues and constant BSOD's go into bios and turn on the game boost or basic auto overclocking and the issue will be resolved. For whatever reason the board seems to undervolt the CPU when running stock out of the box causing major stability issues. I chased down the issue for 3 weeks and was ready to RMA it before coming across this fix on the 13th page of a random forum and haven't had an issue since."

"Bought this board to replace a dead Gigabyte X570 board. Needed something immediately to get my system back up. Good thing as the Gigabyte RMA process is now going on to 8-weeks with no replacement being sent. Anyways, installed the board and the system was back up and running. I was actually amazed that I didn't have to re-install windows it just added the drivers and booted. However after using the board for a couple of weeks, it was very unstable, lots of crashes and system hangs. Decided to system format and do a fresh install of Windows. Discovered the default config with this board was very unstable, constant BSOD's. DMP file analysis showed over 12 recurring issues appearing. Just could not pin it down. Although the Gigabyte board died, the system was stable for 11 months with no issues, the only component change was the motherboard. First thing I did was remove Dragon Center, that software is horrible and that alone drastically improved reliability. However, still would get constant BSOD's mostly when the system was idle. After reading some forums decided to turn Game Boost ON and X-AMP ON in the bios. Not interested in overclocking so never bothered with those settings. However, since the change the system is finally stable. Been 1 week and not one BSOD so far. I think the board is overly aggressive trying to save power when not overclocking. Perhaps it's undervolting too aggressively? Not really sure but if the board is unstable, try turning on the simple overclocking options in the bios."

Tried and enabled game mode and xmp on cbp and pbo. Now it is running at 4.18 Ghz 1.400 Core Voltage (locked) and x42.0 multiplier locked, no random bsod so far in 3 hours, i don't know if is good for the processor lifetime have enable game mode 24/7 lol. What happens? Is my Ryzen 5 3600 bad? Or did I run too unlucky and get 2 bad x570 tomahawks? I really don't know, I need my PC to work, I am an architecture student my free time is mostly limited, and now I am starting to despair :cry:

Ive tried em all. Had issues with Asus, Gigabyte, Biostar, etc. Every manufacturer is gonna have something. This is my first MSI build and I'm pretty happy with it. Just want these stupid reboot issues to be resolved. Before this I had an Asus board for 9 years and the SATA ports started failing one after another, but nothing lasts forever :)
