Just upgraded the MB in one of my servers. Old board was a Supermicro X8DT6-F. New board is a Supermicro X9DRD-7LN4F. Bought the new board about a month ago and fired it up on the bench with a couple of RDIMMS. Just want to verify that it worked. It did.
Final config consisted of a pair of E5 2690V1's and 128GB (16x 8GB). Installed the board in the SC846 and got no post, just low speed fans. Started removing the RDIMMs one at a time and reached the point where it would post but hung at BA code which is memory initialzation. Using the process of elemination I zeroed in on one slot. Remove the RDIMM and the system successfully completed POST. Replaced the RDIMM and it hung at BA again. Almost accepted that the slot was bad even tho visually I saw nothing different. Then I vaguely remembered reading on here that the CPU can cause memory slot problems. I had set of E5 2670's so decided to install them and see what happens. Everything then was normal. All memory slots were working properly and no post hang. Spent the rest of the day running diags and benchmarks with zero problem so apparent the E5 2690 set is bad, either one or both. I visually inspected them and the CPU sockets with a magnifying glass and a strong light and saw nothing out of the ordinary. Anybody know what might be wrong with the E5 2790's? I don't have a single CPU v1/2 MB to test each CPU individually.
Anybody ever deal with something like this?
TIA
