Memory module installation order for memory mirroring with two processors installed in the compute node.
The following table shows the DIMM population sequence for memory mirroring 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.
