5.4.1.3 Memory Compatibility

Observe the following rules when configuring DDR5 memory modules:
● A server must use DDR5 memory modules of the same part number (P/N code),
● The DDR5 DIMMs of different types (RDIMM and LRDIMM) and specifications
● For details about the optional components, consult your local sales representative

NO TICE
and the memory speed is the minimum value of the following items:
● Memory speed supported by a processor.
● Maximum operating speed of a memory module.
(capacity, bit width, rank, and height) cannot be used together.
or see "Search Parts" in the
The memory can be used with the 3rd generation Intel
processors (Sapphire Rapids). The maximum memory capacity supported by all
processor models is the same.
For details about the capacity type of a single memory module, see "Search
Parts" in the Compatibility
The maximum number of memory modules supported depends on the memory
module type and number of ranks.
NO TE
Each memory channel supports a maximum of eight 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.
Each memory channel supports more than eight ranks for load-reduced DIMMs
(LRDIMMs).
NO TE
A quad-rank LRDIMM generates the same electrical load as a single-rank RDIMM on a
memory bus.
