3900X Linux MCE errors

Getting this error about every 5 minutes. Anyone else?  Is there a fix or is this a bad CPU?

Hi,

Same problem for me on my 3900X. The difference is that error happens on CPU:0.
I've got the error sometimes with a frequency of 15 or 20 minutes. If I do nothing, I have a kernel panic and a reboot. Generally, I reboot before crash to make MCE errors disappear.

I run with this config and, for games, with Linux 5.11.12 (locally compiled) :
