Installation order: memory mirroring with four processors
Memory module installation order for memory mirroring with four processors installed in the server.
The following tables show the DIMM population sequence for memory mirroring when four processors are
installed.
• Processors 1 and 2 are installed in the lower system board of the lower compute tray.
• Processors 3 and 4 are installed in the upper system board of the lower compute tray or in the upper
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.
