I'm getting random BSOD for no reasons, sometimes on idle, sometimes under load. Most of the times the error are "IRQL_NOT_LESS_OR_EQUAL" or "page_fault_in_nonpaged_area"
And most of my games are randomly crashing without the generation of crash reports (LoL, Dofus, Trackmania, Skyrim, Rocket League etc)
I've tried to run memtest on my memory, and everything is fine. I already have changed my motherboard thinking it was its fault (msi x570 a pro --> Gigabyte b550 aorus elite) but it didn't helped.
So I brought my PC to a professional, he tested the memory in another PC : fine
He checked my PSU : fine (corsair RM1000)
So now I'm thinking that I have a faulty CPU (R5 3600X) since it is running very hot for apparently no reason (50°C idle with an AIO water-cooling) and even reaching 80°C under full load.
Another clue for the faulty CPU is that HWINFO64 tells me that I have nearly 50% power reporting deviation under full load (cinebench R20 or Folding@home). This was the same with the old motherboard.
Things I have tried :
So here I am, desperately seeking for help, thank you by advance !
While it certainly can be a faulty CPU, memory, GPU, etc... I would highly suggest you check your power supply. Folding at home puts your system under far more stress than most workloads including gaming. It will tax the CPU and GPU at the same time pulling maximum power draw from the PSU. Thus it will often show a weak or defective power supply. Or one that is fine but really not quite powerful enough for full workloads. So while you tried another PSU if it is of the same wattage or still not enough, it may be the issue.
There is a program called OCCT from osbase dot com that you can check the PSU with. You could also use HWINFO and watch the voltage for drop while running folding at home.
You can contact AMD support here for help: https://www.amd.com/en/support/contact-email-form
Your motherboard support department may be able to help you trouble shoot the issue.
Also if you need to begin a warranty rma on the processor you can start that here: https://www.amd.com/en/support/kb/warranty-information/rma-form
after 15mn of OCCT, no problem found. I have a 1000W PSU and the problem can appear pretty independently of the load I put on it so it don't seem to be the problem.
I've also tried replacing the PSU for a 750W one, which was still enough (approx. 550W needed) and the problem remained.
It is good you checked the PSU. At least you now know that is definitely not the issue.
I would proceed to talk with the support departments for you motherboard and AMD for any additional trouble shooting advice.
Have you tried changing some BIOS settings? 1.475mV is your max. core voltage. Have you tried to give 1.5 core voltage manually? Have you tried to increase the VRM level and Load Line Calibration settings within the VRM settings with the BIOS?
Edit: These changes will cause your processor to get more hot. Therefore, use your system without using a test program. So the important thing is to find out how stable the system remains for this.
