Hi,

We attempted an upgrade of our PowerEdge R810 to 32GB DIMMs but we get the "No configurable memory detected" error. After searching all the info we could find, we cannot get past this issue.

Our R810 configuration - 4x8 Core 2.6Ghz (E7-8837) CPU - originally 256GB RAM with 32x8GB DIMMs. The R810 is 10th Gen ii model.
After removing the RAM we installed the new 32GB DIMMs using the system manual guide:
A1,A3,A2,A4
B1,B3,B2,B4
C1,C3,C2,C4
D1,D3,D2,D4

Node Interleaving and Redundant Memory are both disabled.

We then replaced the 32GB DIMMs with the 8GB and rebooted back to 128GB RAM and all was ok. BIOS was double checked and is at version 2.11.0 (the latest available).

We then added the 32GB DIMMs and rebooted to get the same "No configurable memory detected" error. We Reset the BIOS and NVRAM, reinstalled only the 32GB DIMMs and rebooted. Again the error came back.

Repopulated the 8GB DIMMs and rebooted fine.

Any help would be greatly appreciated!
