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.
