Installation order: memory mirroring with two processors

Memory module installation order for memory mirroring with two processors installed in the server.

The following table shows the DIMM population sequence for memory mirroring when two processors are installed.

  • Processors 1 and 2 are installed in the lower system board of the lower compute tray.

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.
