Install the memory modules in the primary memory channels first. If the primary
memory channel is not populated, the memory modules in secondary memory
channels cannot be used.

2.3.1.3 Memory Compatibility
Observe the following rules when configuring DDR4 DIMMs:
NO TICE
● A server must use the same model of DDR4 DIMMs, and all the DIMMs operate
at the same speed, which is the smallest value of:
●
Memory speed supported by a processor
●
Maximum operating speed of a DIMM
● The DDR4 DIMMs of different types (RDIMM and LRDIMM) and specifications
(capacity, bit width, rank, and height) cannot be used together.
● Contact your local Huawei sales representative or use the
to determine the components to be used.
