I played the last boot capture and see a Disabled DIMM. Not sure how our monitoring missed this one. Thanks!
Server has 4*4GB. But ESX sees only 12GB. Which BIOS setting needs changing? :emotion-10: It came from Dell like this, nothing was changed: DIMM.Socket.B3 Type  DDR3 DIMM   Size  4096 MB DIMM.Socket.B2 Type  DDR3 DIMM   Size  4096 MB DIMM.Socket.A3 Type  DDR3 DIMM   Size  4096 MB DIMM.Socket.A2 Type  DDR3 DIMM   Size  4096 MB How do I know idf one is broken? iDRAC reports all is well.
PowerEdge R610 - ESX 4.1 only sees 12GB RAM out of 16GB
