Table 40. Memory population rules (continued)
Processor
Configuration
Memory population
Memory population information
•
Requires three ranks or more per channel.
Fault resilient population
order
{1, 2, 3, 4, 5, 6} {7, 8, 9, 10,
11, 12}
Supported with 6 or 12 DIMMs per processor.
Dual processor (Start
with processor1.
processor1 and
processor 2 population
should match)
Optimized (Independent
channel) population order
A{1}, B{1},
A{2}, B{2},
A{3}, B{3},
A{4}, B{4},
A{5}, B{5},
A{6}, B{6}
Odd number of DIMM population per processor 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 16 DIMMs installations for dual processor.
•
For 8 DIMMs: A1, A2, A4, A5, B1, B2, B4, B5
•
For 16 DIMMs:
A1, A2, A4, A5, A7, A8, A10, A11
B1, B2, B4, B5, B7, B8, B10, B11
Mirroring population order
A{1, 2, 3, 4, 5, 6},
B{1, 2, 3, 4, 5, 6},
A{7, 8, 9, 10, 11, 12},
B{7, 8, 9, 10, 11, 12}
Mirroring is supported with 6 or 12 DIMMs per
processor.
Single rank sparing
population order
A{1}, B{1},
A{2}, B{2},
A{3}, B{3},
A{4}, B{4},
A{5}, B{5},
A{6}, B{6}
•
DIMMs must be populated in the order
specified.
•
Requires two ranks or more per channel.
Multi rank sparing
population order
A{1}, B{1},
A{2}, B{2},
A{3}, B{3},
A{4}, B{4},
A{5}, B{5},
A{6}, B{6}
•
DIMMs must be populated in the order
specified.
•
Requires three ranks or more per channel.
Fault resilient population
order
A{1, 2, 3, 4, 5, 6},
B{1, 2, 3, 4, 5, 6},
A{7, 8, 9, 10, 11, 12},
B{7, 8, 9, 10, 11, 12}
Supported with 6 or 12 DIMMs per processor.
Removing a memory module
The procedure for removing a DIMM module and an NVDIMM-N module is identical.
Prerequisites
1. Follow the safety guidelines listed in
on page 65.
2. Follow the procedure listed in
Before working inside your system
CAUTION:
To prevent data loss and potential damage to your system, ensure that your system, LEDs on system,
LEDs on NVDIMM-N and LEDs on NVDIMM-N battery are turned off before removing the NVDIMM-N battery.
