1.
a: The maximum number of DDR4 DIMMs supported is based on the 2-processor
configuration.
2.
b: The maximum capacity of DDR4 DIMMs supported needs to consider CPU type,
and its maximum value at full load is selected here.
3.
c: DIMM Per Channel (DPC), the number of DIMMs configured per memory
channel.

4. DIMM Population Guidelines
This section describes the DIMM population guidelines when DDR4 DIMMs are fully
configured.
General population guidelines for DDR4 DIMMs:
Install DIMMs only when the corresponding processor is installed.
Mixed use of LRDIMMs and RDIMMs is not allowed.
Install dummies in the DIMM slots where no DIMMs are installed.
Population guidelines for DDR4 DIMMs in specific modes:
