5.2.4.1.3 Memory Compatibility
Observe the following rules when configuring DDR4 memory modules:
⚫
A server must use DDR4 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 CPU
⚫
Maximum operating speed of a memory module
⚫
The DDR4 DIMMs of different types (RDIMM and LRDIMM) and specifications
(capacity, bit width, rank, and height) cannot be used together.
⚫
Contact your local sales representative or see "Search Parts" in the Compatibility Checker
to determine the components to be used.
⚫
The memory can be used with the third-generation Intel
®
Xeon
®
Scalable Ice Lake
processors. The maximum memory capacity supported by all processor models is the
same.
⚫
The total memory capacity is the sum of the capacity of all DDR4 memory modules.
