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 2400 MT/s, 2133 MT/s, or 1866 MT/s depending on the
following factors:
l
System profile selected (for example, Performance Optimized, Custom, or Dense
Configuration Optimized)
l
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.
