System memory

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

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

Memory bus operating frequency can be 1866 MT/s, or 2133 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

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.

NOTE: DIMMs in sockets A1 to A12 are assigned to processor 1 and DIMMs in sockets B1 to B12 are

assigned to processor 2.
