Installation order
Memory modules must be installed in a specific order based on the memory configuration that you
implement on your node.
The following memory configurations are available:
Independent memory mode population sequence
Table 5. DIMM installation sequence (Independent mode/normal mode)
Number of processor
Installation sequence (connectors)
Processor 1 installed
6, 3, 7, 2, 8, 1, 5, 4
Processor 1 and 2 installed
6, 14, 3, 11, 7, 15, 2, 10, 8, 16, 1, 9, 5, 13, 4, 12
Memory mirroring population sequence
Table 6. DIMM installation sequence (mirror mode/lockstep mode)
Number of processors
Installation sequence (connectors)
Processor 1 installed
(6, 7), (2, 3), (8, 1)
Processor 1 and 2 installed
(6, 7, 14, 15), (2, 3), (10, 11), (1,8), (9, 16)
If you are installing 3, 6, 9 or 12 identical DIMMs for the mirroring mode, comply with the following installation
sequence to achieve the best performance.
Table 7. DIMM installation sequence (mirror mode/lockstep mode for 3, 6, 9 and 12 identical DIMMs)
Number of processors
Installation sequence (connectors)
Processor 1 installed
(6, 7, 8), (1, 2, 3)
Processor 1 and 2 installed
(6, 7, 8), (14, 15, 16), (1, 2, 3), (9, 10, 11)
Memory rank sparing population sequence
Table 8. DIMM installation sequence (sparing mode)
Number of processors
Installation sequence (connectors)
Processor 1 installed
6, 3, 7, 2, 8, 1, 5, 4
Processor 1 and 2 installed
6, 14, 3, 11, 7, 15, 2, 10, 8, 16, 1, 9, 5, 13, 4, 12
Note:
Single-rank RDIMM is not supported by sparing. If you install single-rank RDIMM, it switches to the
independent mode automatically.
