I’m trying a new CPU in my PC (Ryzen 5500GT) and I’m seeing:
- Sporadic kernel panics during boot.
- Random .ko.zst module files (different one each boot) complaining that ZST decompression failed checksum.
- Random .so’s failing to find a symbol and causing programs to crash/fail to start.
- Started a stress-ng sequential session at 5s per stressor and it hung up after a dozen stressors. Couldn’t ctrl-c it and also
psdidn’t work anymore. 😅
Funny thing is, other than that the system runs fine (when it boots, that is).
Switched back to my old CPU (that’s the only change in the machine) and all of these things stopped.
That CPU that’s doing that is defective, correct? Just double-checking I’m not missing anything else.
I’ve reset BIOS between CPU swaps and left it at defaults. Could default settings cause a CPU to act like this?
Edit: cooling is good, all temps (chipset, CPU etc.) are in the 30’s C in idle, CPU went up to 75C when stressed. Have a tower cooler (Scythe Kotetsu) with a 120mm fan.
I’m also adding some voltage readings I took from sensors while the problematic CPU was installed:
Vcore: 840mV
+3.3V: 3.31V
+12.0V: 12.10V
+5.0V: 5.01V
VSOC: 780mV
VDDP: 900mV
DRAM: 1.21V
3VSB: 3.29V
VBAT: 3.26V
I don’t think overheating would cause random corruptions (it should throttle down when overheating, and then shut down if the temperature gets too high even when throttled, but there should never be an incorrect result of any computation), and surely the RAM will run at the standard 2133 speed on default settings - OP says they reset the BIOS settings to default between CPU swaps.
RAM is indeed at 2133 MHz and the cooling is great, got a tower cooler (Scythe Kotetsu mark II), idle temps are in the low 30’s C, stress temp was 76C.
