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 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.
