l
A server must use the same model of DDR4 memory modules, and all the memory
modules operate at the same speed, which is the smallest value of:
l
Memory speed supported by a processor
l
Maximum operating speed of a memory module
l
The DDR4 memory modules of different types (RDIMM and LRDIMM) and
specifications (capacity, bit width, rank, and height) cannot be used together.
l
Contact your local Huawei sales representative or use the
to determine the components to be used.
l
The memory can be used with Intel
®
Xeon
®
Scalable Skylake and Cascade Lake
processors. The maximum memory capacity supported varies depending on the
processor model.

M processors: 1.5 TB/socket

Other processors: 768 GB/socket
–
Cascade Lake processors

L processors: 4.5 TB/socket

Other processors: 1 TB/socket
l
The total memory capacity is the sum of the capacity of all DDR4 memory modules.
NO TICE
The total memory capacity cannot exceed the maximum memory capacity supported by
the CPUs.
l
Intelligent Computing Compatibility Checker
to determine the capacity type
of a single memory module.
l
The maximum number of memory modules supported by a server varies depending on
the CPU type, memory type, rank quantity, and operating voltage.
Each memory channel supports a maximum of 8 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
l
A memory channel supports more than eight ranks for LRDIMMs.
A quad-rank LRDIMM generates the same electrical load as a single-rank RDIMM on a memory
bus.
