Folding Forum

Greetings!

I have a few years F@H and now at 1.3 billion on Team Fark 2233

Odd behavior 1:
I run dual NVidia cards and 16 cores / 32 threads folding. Occasionally my system will reset with a CPU core error.

Odd behavior 2:
In my attempt to halt the hardware errors and reboot, I will set the CPU folding to "Finish" Which the machine will do, but then my CPU temperatures spike! Seriously, WHILE FOLDING my CPU temp is ~50c. When I HALT FOLDING my CPU temp will run ~60-65c. Curious, I would never expect this behavior.

I run a Gigabyte Aorus x570s chipset, on ECO mode, with PBO disabled.

Daft suggestion but have you done any stress testing with the likes of memtest86+ and prime95?

When I first built my Ryzen system I had a dodgy core. At the time I got away with adjusting the vcore until the failing core stabilized. I ended up replacing the motherboard about a year later, after my system crashed and rebooted three days in a row. I eventually worked out the VRMs were too weak for the processor.
