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:
• 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.
