System memory

Your system supports DDR4 registered DIMMs (RDIMMs) and load registered DIMMs (LRDIMMs).

NOTE: MT/s indicates DIMM speed in MegaTransfers per second.

Memory bus operating frequency can be 1333 MT/s, 1600 MT/s, 1866 MT/s, 2133 MT/s, or 2400 MT/s depending on the following factors:

  • DIMM type (RDIMMs or LRDIMMs)
  • Number of DIMMs populated per channel
  • System profile selected (for example, Performance Optimized, Custom, or Dense Configuration Optimized)
  • Maximum supported DIMM frequency of the processors

The system contains 16 memory sockets split into two sets of 8 sockets, one set per processor. Each 8-socket set is organized into four channels. In each channel, the release levers of the first socket are marked white and the second socket black.

NOTE: DIMMs in sockets A1 to A8 are assigned to processor 1 and DIMMs in sockets B1 to B8 are assigned to processor 2.

This figure helps in locating memory sockets.
Table 1. Memory channelsMemory channels are organized as follows:
Processors Memory channel Memory channel Memory channel Memory channel
Processor 1channel 0: slots A1, A5 channel 1: slots A2, A6 channel 2: slots A3, A7 channel 3: slots A4, A8
Processor 2channel 0: slots B1, B5 channel 1: slots B2, B6 channel 2: slots B3, B7 channel 3: slots B4, B8

The following table shows the memory populations and operating frequencies for the supported configurations:

Table 2. Memory populationThe following table shows the memory populations and operating frequencies for the supported configurations.
DIMM Type DIMMs Populated/Channel Voltage Operating Frequency (in MT/s) Maximum DIMM Rank/Channel
RDIMM 1 1.2 V 2400, 2133, 1866, 1600, 1333 Dual rank or single rank
2 2400, 2133, 1866, 1600, 1333 Dual rank or single rank
LRDIMM 1 1.2 V 2400, 2133, 1866, 1600, 1333 Quad rank
2 2400, 2133, 1866, 1600, 1333 Quad rank
