Removing a memory module

The procedure for removing a DIMM module and an NVDIMM-N module is identical.
Prerequisites

Memory population information
● DIMMs must be populated in the order
specified.
● Requires two ranks or more per channel.
● DIMMs must be populated in the order
specified.
● Requires three ranks or more per channel.
Supported with 6 or 12 DIMMs per processor.
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 is supported with 6 or 12 DIMMs per
processor.
● DIMMs must be populated in the order
specified.
● Requires two ranks or more per channel.
● DIMMs must be populated in the order
specified.
● Requires three ranks or more per channel.
Supported with 6 or 12 DIMMs per processor.
