⚫
For details about the capacity type of a single memory module, see "Search Parts" in the
Compatibility Checker.
⚫
The maximum number of memory modules supported depends on the memory type and
rank quantity.
Each memory channel supports a maximum of 8 ranks. The number of memory modules supported by
each channel varies depending on the number of ranks supported by each channel:
Number of memory modules supported by each channel ≤ Number of ranks supported by each memory
channel/Number of ranks supported by each memory module

a: The maximum number of DDR4 memory modules is based on dual-processor
configuration. The value is halved for a server with only one processor.
⚫
b: DPC (DIMM per channel) indicates the number of memory modules per channel.

5.2.4.1.4 DIMM Installation Rules
Observe the following when configuring DDR4 memory modules:
⚫
Install memory modules only when corresponding processors are installed.
⚫
Do not install LRDIMMs and RDIMMs in the same server.
⚫
Install filler memory modules in vacant slots.
Observe the following when configuring DDR4 memory modules in specific operating mode:
⚫
Memory sparing mode
− Comply with the general installation guidelines.
− Each memory channel must have a valid online spare configuration.
− The channels can have different online spare configurations.
− Each populated channel must have a spare rank.
