Installation order: independent memory mode with four processors

Memory module installation order for independent (non-mirroring) memory mode with four processors installed in the compute node.

The following tables show the DIMM population sequence for independent memory mode when four processors are installed.

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.
