●
The total memory capacity is the sum of the capacity of all DDR4 DIMMs.
NO TICE
The total memory capacity cannot exceed the maximum memory capacity
supported by the CPUs.
●
Intelligent Computing Compatibility Checker
to determine the
capacity type of a single DIMM.
●
The maximum number of DIMMs 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 DIMMs
supported by each channel varies depending on the number of ranks supported by
each channel:
Number of DIMMs supported by each channel ≤ Number of ranks supported by each
memory channel/Number of ranks supported by each DIMM
●
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.
