I'm trying to set up an Unraid server on an old desktop. I've had it running for about a week, but I've experienced frequent reboots due to a MCE. It's always the same error, just a different address. I've played around with the BIOS settings including restoring the default settings. I'm also currently running a MemTest, but so far no errors through 2 passes. I've attached some of the MCE failure logs and my diagnostics bundle. Any help would be greatly appreciated.

Looks like a CPU cache problem.

Any advice on how to troubleshoot or am I going to have to replace the CPU? 

Basically you'd need to try with a different CPU to confirm.

Thanks for the help. If I continue to have issues I'll look into replacing the CPU.
