I'm a new Unraid user. My system has been up and running for a little over a week, but I am experiencing random reboots, I installed the mcelog, and shortly after reboot I get this:

 

Apr 29 18:17:16 Tower kernel: mce: [Hardware Error]: Machine check events logged

Though later on, I get

 

Apr 29 18:27:05 Tower root: mcelog: ERROR: AMD Processor family 23: mcelog does not support this processor.  Please use the edac_mce_amd module instead.

 

So, I am not sure if I can trust the earlier detection.

 

Anyone have any ideas? I will note that this is a new build; everything in this system is brand new except for two drives I moved from my old media server.

There are some known issues with Ryzen, most workarounds are discussed here.

Thanks. Changing the c6 setting brought stability back to my system.
