Identifying DIMMs
Note - The DIMM sparing feature is available only in fully-populated servers.
■
All DIMMs associated with each processor must be identical (same size, same rank
classification).
Mixed configurations are supported (DIMMs associated with CM0 with one size, and DIMMs
associated with CM1 with a different size) as long as all DIMMs in the server have the same
rank classification, and the number of DIMM in CM0 and CM1 are the same. For example,
sixteen 32 Gbyte DIMMs associated with CM0, and sixteen 64 Gbyte DIMMs associated with
CM1.

Identifying DIMMs
Each DIMM is affixed with an identifying label. The first four characters on the label describe
the DIMM memory capacity; the second four characters describe the rank classification.
Use these labels to identify the DIMMs installed in the server, to verify that any replacement
DIMMs are compatible, or to confirm that upgrade DIMMs may be installed in a supported
configuration.
