5.4.1.3 Memory Compatibility
Observe the following rules when configuring DDR5 memory modules:
NO TICE
● A server must use DDR5 memory modules of the same part number (P/N code),
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.
● The DDR5 DIMMs of different types (RDIMM and LRDIMM) and specifications
(capacity, bit width, rank, and height) cannot be used together.
● For details about the optional components, consult your local sales representative
or see "Search Parts" in the
●
The memory can be used with the 3rd generation Intel
®
Xeon
®
Scalable
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
.
●
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.
