Installation order: Memory Mode with two processors

Memory module installation order for Memory Mode with two processors installed in the compute node.

The following table shows the DIMM population sequence for Memory Mode when two processors are installed.

Note
When adding one or more DIMMs during a memory upgrade, you might need to move other DIMMs that are already installed to new locations.
Table 1. Memory Mode with two processors

D: DRAM DIMMs with 16 GB or larger capacity.

P: Only DC Persistent Memory Module (DCPMM) can be installed on the corresponding DIMM slots.
