Memory population information
● Populate in this order, odd
amount 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 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
Mirroring is supported with 6
DIMM slots per processor.
Populate in this order, odd amount
allowed. Requires two ranks or
more per channel.
Populate in this order, odd amount
allowed. Requires three ranks or
more per channel.
● 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
