I'm attempting to upgrade the CPU in a DL320 G6, however I'm running into issues with the ram. On the stock Xeon E5504 the system boots fine with no errors, however with a W3520 I get an error "207 Invalid Memory Configuration - System Halted". The memory config is 3x 2 GB Reg ECC and 4x 4 GB Reg ECC, 2 gigs in slots A B C and 4 gigs in D E G H. The system complained about the 4s in D E F G with the E5504 and makes no different with the W3520.
For configurations of ram I have tried the normal all 22 GB, 3x 2 GB in ABC, 2x 2 GB in AB, 1x 2 GB in A, 1x 2 GB in C, 1x 4 GB in A, 2x 4 GB in AB and 3x 4 GB in ABC with no change at all. I know for certain it's not a problem with ECC based on the system actually posting (on-CPU mem controller) and I know the ram works being as it'll boot fine with the E5504. Unfortunately I can't update the BIOS due to the system being out of warranty and the support requirements so I can't test that out.
Is there anything else I can try or is the W3520 just never going to work (despite being on the supported CPU list)?.
Note: I've attached two pictures, one of the error and one of it going through fine.
