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 depending on the following factors:
• System prole selected (for example, Performance Optimized, Custom, or Dense Conguration 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 rst 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.
