Question Persistent BSODs when gaming - AuthenticAMD.sys error, Hypervisor Fatal error etc.

[MorganDally]

I am running on Ryzen 9 5900X, X570 Tomahawk Wifi, 64GB DDR4 3200Mhz, Radeon RX 7600 XT and previously RTX 3060 and for several weeks I have been getting BSOD's every time I try and game, on both GPU's, sometimes after 30 seconds, other times after 30 minutes.
Mini dump files either pointed to AuthenticAMD.sys or some sort of Hypervisor fatal error. I did get others as well which just convoluted any fault finding.

Things I tried:

Updating BIOS.
Updating chipset.
Wiping Windows 11.
Wiping Steam.
Reseating all componants.
Memtest.
CPU stress test.
GPU stress test.
Driver checks.
Installing Hyper-V and updating.
Removing Hyper-V.
Removing any virtualisation platform.
Using DDU to remove graphics drivers in safe mode.

Nothing worked and I was really at my limit of trying to fix this thing.

What DID work:

After more digging, I came across someone with a similar setup who suggested turning off Precision Boost Overdrive (PBO) and Core Performance Boost (CPB) within BIOS which seems to have worked great. Yes I lose a bit of performance, but not enough to regret doing it as I can now use my PC again without wondering when it will crash.

I thought I should post this here as I know this is an issue quite a few people face and hopefully this will prevent them going in circles like I did.

Couple questions...

What is the make/model of your power supply?

Is your memory 2x32GB or 4x16GB?

What, if anything, were you overclocking (CPU, GPU, memory)?

 

[MorganDally]

Power Supply is: Cooler Master MWE Gold v2 650W Modular PSU

Memory is 4 x 16GB.

No overclocking, I did have XMP enabled for a while but turned that off some months ago. This issue started after a BIOS update but despite reverting and clearing CMOS, the problem persisted.

All working and stable now though after disabling PBO and CPB.

I suspect your issue is related to the 4x16GB memory configuration. If you had 2x32GB, then the chances of the same issue is lower.

The issue is likely one of power and memory stability when all four slots are used. A "fix" for this is to bump up the memory voltage setting in the BIOS. In the smallest possible increment, until stable.

Can you please download the SysnativeBSODCollectionApp and save it to the Desktop. Then run it and upload the resulting zip file to a cloud service with a link to it here. The SysnativeBSODCollectionApp collects all the available troubleshooting data and will make diagnosing your problem much easier. It DOES NOT collect any personally identifying data. It's used by several highly respected Windows help forums (including this one). I'm a senior BSOD analyst on the Sysnative forum where this tool came from, so I know it to be safe.

You can of course look at what's in the zip file before you upload it, most of the files are txt files. Please don't change or delete anything though. If you want a description of what each file contains you'll find that here.
