I installed 2 e5-2667 v2 processors (used w/ warranty) into my unraid server which has been running stable for some time now with 2x e5-2630's. I figured with the upgrade that I should isolate cpus and get the most out of my gaming VM. So I isolated all cores from the second processor, 8-15 & 24-31, and assigned them to a gaming vm. The server crashes after 20-30 minutes. I remove the unraid isolation and the server remains stable for over 24 hours and to confirm rebooted with core isolation, server crashes.
Anyone have any idea of what can be going on here?
