General DIMM slot population guidelines

Observe the following guidelines for all AMP modes:

• Install DIMMs that are optimized for the installed processor.

  To identify the processor type installed in the server, use the BIOS/Platform Configuration (RBSU) of the UEFI System Utilities .

• Install DIMMs only if the corresponding processor is installed.
• Do not mix LRDIMMs and RDIMMs.
• When only one processor is installed, install DIMMs in sequential alphabetic order: Ch 1-A, Ch 2-B, Ch 3-C, Ch 4-D.
• When two processors are installed, install the DIMMs in sequential alphabetical order balanced between the two processors: P1-A, P2-A, P1-B, P2-B, P1-C, P2-C, P1-D, P2-D.
