System memory The system supports DDR4 registered DIMMs (RDIMMs) and load reduced DIMMs (LRDIMMs). System memory holds the instructions that are executed by the processor. NOTE: MT/s indicates DIMM speed in MegaTransfers per second. Memory bus operating frequency can be 1866 MT/s, 2133 MT/s, or 2400 MT/s depending on the following factors: ● DIMM type (RDIMM or LRDIMM) ● 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 Your 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 tabs of the first socket are marked white, the second socket black, and the third socket green. Figure 28.

System memory
The system supports DDR4 registered DIMMs (RDIMMs) and load reduced DIMMs (LRDIMMs). System memory holds the
instructions that are executed by the processor.
NOTE:
MT/s indicates DIMM speed in MegaTransfers per second.
Memory bus operating frequency can be 1866 MT/s, 2133 MT/s, or 2400 MT/s depending on the following factors:
●
DIMM type (RDIMM or LRDIMM)
●
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
Your 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 tabs of the first socket are marked white, the second socket black,
and the third socket green.
