System memory

Your system supports DDR4 registered DIMMs (RDIMMs).

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

Memory bus operating frequency can be 2133 MT/s, 1866 MT/s, 1600 MT/s, or 1333 MT/s depending on

the following factors:

• System profile selected (for example, Performance Optimized, Custom, or Dense Configuration

Optimized)

• Maximum supported DIMM frequency of the processors

The system contains 12 memory sockets split into four sets—two sets of 4 sockets and two sets of 2

sockets each. Each 4-socket set is organized into two channels and each 2–socket set is organized into

one channel. In each channel of the 4-socket set, the release levers of the first socket are marked white

and the second socket black. In the 2-socket set, each release lever is marked white.

NOTE: DIMMs in sockets A1 to A8 are assigned to processor 1 and DIMMs in sockets B1 to B4 are

assigned to processor 2.
