Installation order: independent memory mode with eight processors
Memory module installation order for independent (non-mirroring) memory mode with eight processors
installed in the server.
The following tables show the DIMM population sequence for independent memory mode when eight
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.
• Processors 5 and 6 are installed in the lower system board of the upper compute tray.
• Processors 7 and 8 are installed in the upper system board of 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.
