Installation order: memory sparing with four processors
Memory module installation order for memory sparing with four processors installed in the server.
The following tables show the DIMM population sequence for memory sparing 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:
An even number of DIMMs is required for memory sparing.
