[Hardware error] CPU, Memory, PCIe

[sfaruque]

Good evening

 

I've been getting these errors below after upgrading from 6.8.3 to 6.9.2 recently. The server appears to be running fine but I'm worried as these errors were not noticed before the upgrade.

 

I have a AMD Radeon R7 passed through to a Windows 10 VM. I recently added more ECC Kingston RAM (Total 16GBx4).

 

MB: Asrock X570 Steel Legend

CPU: AMD Ryzen 7 3700X

 

Recent diagnostics attached. Any help is much appreciated.

 

Thanks

Are there any symptoms you are noticing or just errors in logs?

Looks like a bad stick

I haven't noticed any symptoms - just errors in the logs.

I'll remove the new sticks and see. Could there be any long term consequences if I leave them there do you think? As the server appears to be running fine.

Looks like it was bad DRAM sticks. I've removed them and errors have disappeared. Thanks for your help.

My opinion:

 

You purchased ECC memory and are using it so that if/when one starts going bad you can replace it.  Sure the errors are currently being corrected, but that is simply the stick telling you "replace me".  If you have ECC memory and chose to not replace the memory when errors begin to happen then I'd question why you even bought ECC memory and a compatible CPU / motherboard in the first place.

Very valid point. Noted. Thanks.
