Table 2-5 DDR4 memory specifications
Parameter
Maximum capacity per DDR4 DIMM (GB)
Rated speed (MT/s)
Operating voltage (V)
Maximum number of DDR4 DIMMs in a node
Issue 17 (2021-03-09)
The memory can be used with Intel
Lake processors. The maximum memory capacity supported varies depending
on the processor model.
–
Skylake processors
▪
M processors: 1.5 TB/socket
▪
Other processors: 768 GB/socket
–
Cascade Lake processors
▪
L processors: 4.5 TB/socket
▪
M processors: 2 TB/socket
▪
Other processors: 1 TB/socket
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.

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.
