Thanks, It wasn't overclocked but I've knocked it down to 1866 and turned off c-states. Hopefully that fixes it! Strangely it seems to only be when the machine is idling. Update: now 3+ days of uptime without any issues! Thanks for suggesting the RAM fix. Hard to say if it was that or the c-state issue, but appreciate the assistance nevertheless.

Updating the bios did not help. Here is the last logs around the last seemingly unprovoked reboot.

I've updated the bios to the most recent firmware (7.40) and no longer see those errors in syslog. Hopefully that will fix the issue.

Hello all, I've set up Unraid to use as a NAS and Plex server using some old hardware. The RAM sticks passed Memtest after 4 or so hours, I've pushed the CPU to try to get it to overheat and it did fine, removed all extraneous drives. I reset the BIOS and everything works fine except for the restarts. They only seem to happen when the server is not working. I wrote syslog to flash (attached) and Fix Common Problems tells me that I have MCEs.
