3. Compatibility
Refer to the following rules to select the DDR4 DIMMs:

A server must use DDR4 DIMMs with the same part number (P/N code). All
DDR4 DIMMs operate at the same speed, which is the lowest of:
‐ Memory speed supported by a specific CPU
‐ Maximum operating speed of a memory configuration

Mixing DDR4 DIMM types (RDIMM, LRDIMM) or mixing DDR4 DIMM
specifications (capacity, bit width, rank, height, etc.) is not supported.

For specific system memory options, consult your local Inspur sales
representative or refer to
7.2 Hardware Compatibility .

An RDIMM supports up to 4 ranks and an LRDIMM supports up to 8 ranks.

Maximum number of DIMMs supported per channel ≤ Maximum number of
ranks supported per channel/Number of ranks per DIMM.
One quad-rank LRDIMM provides the same electrical load on a memory bus as a
single-rank RDIMM.
