Something weird with my Windows 11 / Ryzen 5 5600X

Hi all! Recently (about 2-3 weeks ago) the last 3 cores of processor stopped loading almost completely, no matter what load I was doing (in the screenshot - rendering video in premiere pro), in games the situation is similar. I have Windows 11 22H2 22631.900

The motherboard is Gigabyte B450M S2H, BIOS F64A
Processor - Ryzen 5 5600X, PBO enabled
Power scheme - high performance.


Interesting fact, but on ubuntu the core loading is correct, so something is probably in the system.

Yes, I have tried the Ryzen Balanced power profile as well as other power profiles like High Performance, Balanced, Power Saver, and even custom profiles like RCPP (Ryzen Custom Power Plan).

Was the bios updated recently? Did you clear CMOS after update?

I updated the bios quite some time ago, and I did clear CMOS before installing the new bios update.

Clear CMOS once more. It needs to be done after the bios update. Otherwise old microcode can hold over and cause issues.

See if we can rule out things one by one.

What are you using to monitor your system? Try HWInfo. It's the most reliable.

It is a bit odd that Ubuntu shows the cores working.

Try load up Cinebench R23, run the multi and see if the scores are where they are expected.

It might be worth considering re-installing Windows, while keeping your files. It could be an OS issue.

I used regular task manager, but HWInfo shows the same core load. I will try now to update the bios to stable F64 version and clear CMOS

I updated the bios, but the cores still won't load. Checked in Cinebench R15 and compared to December's results, the scores are down 458 points.

Sid you OC your setup in the past?

Sid you OC your setup in the past?

Only RAM, from 3200 to 3600

I think the reason lies in Windows, because if I set the affinity specifically to these 3 cores, they load normally.

 

[AndreyRGW]

Interesting fact, if I go into msconfig and set it to 10 or 11 cores, the core load is normal, but if I uncheck or set 12, the load is as in the screenshot.

So, I upgraded Windows via ISO image and cores are working again!
