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 on the system board.
• Processors 3 and 4 are installed in the processor and memory expansion tray.
Note:
When adding one or more DIMMs during a memory upgrade, you might need to remove some DIMMs
that are already installed to new locations.
