● a: The maximum number of DDR4 DIMMs is based on dual-processor
conguration. 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 congured.
● 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.
2.4.4 Memory Installation Guidelines
● Observe the following when
conguring DDR4 DIMMs:
– Install DIMMs only when corresponding processors are installed.
– Do not install LRDIMMs and RDIMMs in the same server.
– Install
ller DIMMs in vacant slots.
● Observe the following when conguring DDR4 DIMMs in specic operating
mode:
