Installation order: memory sparing with two processors

Memory module installation order for memory sparing with two processors installed in the server.

The following table shows the DIMM population sequence for memory sparing when two processors are installed.

  • Processors 1 and 2 are installed on the system board.

Note

  1. An even number of DIMMs is required for memory sparing.

  2. This mode only applies to single-rank memory modules. When installing DIMMs consisting of more than two ranks, including dual-rank, quad-rank or octal-rank memory modules, refer to Independent memory mode instead.
