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.
Use the Intelligent Computing Compatibility Checker
capacity type of a single memory module.
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
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.
