2.4. 2 Memory compatibility information
The motherboard supports DDR4 RDIMM/LRDIMM server memory, and the memory
frequency supports 2400/2666/2933/3200;
Notice:
The same server must use the same type of DDR4 memory, and all memory must
run at the same speed, and the speed value is the lowest value of the following
items:
Memory speed supported by a particular CPU.
Maximum operating speed for a specific memory configuration.
Different types (RDIMM, LRDIMM) and specifications (capacity, bit width, rank,
height, etc.) do not support mixed use.
The maximum memory capacity supported by different models of AMD EPYC
CPUs is different. (See attachment-AMD CPU memory installation guide for
details)
