Installation order: memory sparing with eight processors

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

The following table shows the DIMM population sequence for memory sparing 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
An even number of DIMMs is required for memory sparing.
