2.3.1.3 Memory Compatibility
Observe the following rules when conguring 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
dierent types (RDIMM and LRDIMM) and specications
(capacity, bit width, rank, and height) cannot be used together.
● Contact your local Huawei sales representative or use the Computing Product
Compatibility Checker to determine the components to be used.
