Installation order: independent memory mode with four processors
Memory module installation order for independent (non-mirroring) memory mode with four processors
installed in the server.
The following tables show the DIMM population sequence for independent memory mode 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.
