Installation order: memory mirroring with three processors
Memory module installation order for memory mirroring with three processors installed in the server.
The following tables show the DIMM population sequence for memory mirroring when three processors are
installed.
• Processors 1 and 2 are installed in the lower system board of the lower compute tray.
• Processor 3 is installed in the upper system board of the lower compute tray or in the upper compute tray
(processor slot 4 or processor slot 6).
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.

• Processor 1 and 2 DIMM population sequences for 25 to 36 DIMMs, see Table 80 "Memory mirroring with
three processors (Processors 1 and 2, 25 to 36 total DIMMs installed in server)" on page 103.
• To continue populating processor 3 for a system with 6 to 24 DIMMs, see Table 81 "Memory mirroring
