I got myself two E5-2666v3 from icomputer_parts_international on eBay. I bought myself a brand new SM X10-DRi. I have 4x 16GB ECC Samsung chips (which seem to be listed as compatable on SM's page). I'm even using a SM 4U 1200 Watt chassis. If I put one CPU in the board, it will boot. Either one will boot. If both are in there, it will not. I've updated BIOS/IPMI. Not sure what to do..
