Memory processor compatibility information

Memory clock frequency
Operating frequency of DDR4 memory varies by processor type and memory configuration.
Please refer to the table below for the actual maximum operating frequency.
CPU brand
Xeon ® Platinum 8100 Series
Xeon ® Gold 6100 Series
Xeon ® Gold 5122 Processor
Xeon ® Gold 5100 Series (except Xeon ® Gold 5122 processor)
Xeon ® Silver 4100 Series
Xeon ® Bronze 3100 Series
The operation memory speed is decided by rating DIMM speed, DIMM attached on each channel, processor
model and speed selected on System Utility.
Depending on the models of processor, the number of DIMM installed and whether LRDIMM or RDIMM is
installed, the memory clock rate may fall to 1,866 MT/s.
The maximum memory capacity
Maximum memory capacity depends on DIMM capacity, the number of installed DIMM, memory type, and the
number of processors installed.
