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 8200 Series
Xeon ® Gold 6200 Series
Xeon ® Gold 5222 Processor
Xeon ® Gold 5200 Series (except Xeon® Gold 5222 processor)
Xeon ® Silver 4200 Series
Xeon ® Bronze 3200 Series
The operation memory speed is decided by rating DIMM speed, DIMM attached on each channel, processor
model and speed selected on System Utility.
 The maximum memory capacity
Maximum memory capacity depends on DIMM capacity, the number of installed DIMM, memory type, and the
number of processors installed.
