at the same speed, which is the smallest value of:
● Memory speed supported by a processor
● Maximum operating speed of a DIMM
(capacity, bit width, rank, and height) cannot be used together.
Computing Compatibility Checker
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.
Use the Intelligent Computing Compatibility Checker
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.
