NO TICE
The total memory capacity cannot exceed the maximum memory capacity
supported by the CPUs.

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.
NO TE
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.
NO TE
A quad-rank LRDIMM generates the same electrical load as a single-rank RDIMM on a
memory bus.

type. The value listed in this table is based on the assumption that DIMMs
are fully configured.
DIMM can reach 2933 MT/s. If the Skylake processor is used, the maximum
operating speed of a DIMM can reach 2666 MT/s only.
