⚫
The maximum number of DIMMs supported by a server varies depending on the CPU
type, memory type, rank quantity, and operating voltage.
Each memory channel supports a maximum of 8 ranks. The number of DIMMs supported by each
channel varies depending on the number of ranks supported by each channel:
Number of DIMMs supported by each channel ≤ Number of ranks supported by each memory
channel/Number of ranks supported by each DIMM

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: The maximum DDR4 memory capacity varies depending on the processor type. The
value listed in this table is based on the assumption that DIMMs are fully configured.
⚫
c: DPC (DIMM per channel) indicates the number of DIMMs per channel.
⚫
d: If the Cascade Lake processor is used, the maximum operating speed of a DIMM can
reach 2933 MT/s. If the Skylake processor is used, the maximum operating speed of a
DIMM can reach 2666 MT/s only. Different CPUs possess different specifications, For
details about the CPU parameters, see the Intel official website.

5.4.1.4 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.
