Processor Configuration Memory population Memory population information
identically with identical
DIMMs for best
performance.
• Optimizer population order is not
traditional for 4 and 8 DIMM
installations of single processor.
• For 4 DIMMs: A1, A2, A4, A5
• For 8 DIMMs: A1, A2, A4, A5,
A7, A8, A9, A10
Mirror population order {1, 2, 3, 4, 5, 6} Mirroring is supported with 6 DIMM
slots per processor.
Single rank sparing population order 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 Populate in this order, odd amount
allowed. Requires two ranks or more
per channel.
Multi rank sparing population order 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 Populate in this order, odd amount
allowed. Requires three ranks or more
per channel.
Dual processor
(Populate round robin
starting with
processor1)
Optimized (Independent channel)
population order
A{1}, B{1}, A{2}, B{2}, A{3},
B{3}...
• Odd amount of DIMM slots per
processor allowed.
• Odd number of DIMM population
is allowed.
NOTE: Odd number of
DIMMs will result in
unbalanced memory
configurations, which in
turn will result in
performance loss. It is
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.
