Your system supports DDR4 registered DIMMs (RDIMMs), and load reduced DIMMs (LRDIMMs).
Memory bus operating frequency can be 1333 MT/s, 1600 MT/s, 1866 MT/s, or 2133 MT/s depending on the following factors:
The system contains 24 memory sockets split into two sets of 12 sockets, one set per processor. Each 12-socket set is organized into four channels. In each channel, the release levers of the first socket are marked white, the second socket black, and the third socket green.
Memory channels are organized as follows:
channel 0: slots A1, A5, and A9
channel 1: slots A2, A6, and A10
channel 2: slots A3, A7, and A11
channel 3: slots A4, A8, and A12
channel 0: slots B1, B5, and B9
channel 1: slots B2, B6, and B10
channel 2: slots B3, B7, and B11
channel 3: slots B4, B8, and B12
The following table shows the memory populations and operating frequencies for the supported configurations.
|DIMM Type||DIMMs Populated/Channel||Operating Frequency (in MT/s)||Maximum DIMM Rank/Channel|
|RDIMM||1||2133, 1866, 1600, 1333||Dual rank or single rank|
|2||2133, 1866, 1600, 1333||Dual rank or single rank|
|3||1866, 1600, 1333||Dual rank or single rank|
|LRDIMM||1||2133, 1866, 1600, 1333||Quad rank|
|2||2133, 1866, 1600, 1333||Quad rank|
|3||1866, 1600, 1333||Quad rank|
