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.
