Table 41. Memory population rules (continued)
Processor
Configuration
Memory population
Memory population information
recommended to populate
all memory channels
identically with identical
DIMMs for best
performance.
•
Optimizer population order is not
traditional for 8 and 14 DIMM
installations of dual processor.
○
For 8 DIMMs: A1, A2, A4, A5,
B1, B2, B4, B5
○
For 14 DIMMs: A1, A2, A4, A5,
A7, A8, A9, A10, B1, B2, B3,
B4, B5, B6
Mirroring population order
A{1, 2, 3, 4, 5, 6}, B{1, 2, 3, 4, 5,
6}
Mirroring is supported with 6 DIMM
slots per processor.
Single rank sparing population
order
A{1}, B{1}, A{2}, B{2}, A{3},
B{3}...
Populate in this order, odd amount
per processor allowed. Requires two
ranks or more per channel.
Multi rank sparing population order A{1}, B{1}, A{2}, B{2}, A{3},
B{3}...
Populate in this order, odd amount
per processor allowed. Requires three
ranks or more per channel.
