Hi, thanks for the photos. I think the bending of the processor socket is the problem.
Hello !  Can someone please assist me on this: Dell R710 ram issue:  I have installed 8gb dimms on slots A1 A4 A2 A5 A3 A6 B1 B4 B2 B5 B3 B6 and 4gh dimms on A7 A8 B7 B8  all of my A slots are MEMBIST FAILURE and are disabled.  I have tried swapping the B series dimms to A and got the same error.  Please advise. Many thanks!
