I just bought parts for my new old dell poweredge 2950 I put the dual xeon e5440s in it and it gives me a cpu mismatch so I take out cpu 1 and it boots just fine (I also put cpu 1 in to the other slot and it worked). When I just loaded in cpu 1 it would give me e1410 IERR i looked at the socket and 4 pins were bent moderately. So will bent pins cause this error.
