System memory
Your system supports DDR4 registered DIMMs (RDIMMs). It supports DDR4 voltage specifications.
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:
•
System profile selected (for example, Performance Optimized, Custom, or Dense Configuration Optimized)
•
Maximum supported DIMM frequency of the processors
Your system contains 12 memory sockets split into four sets— two sets of 4 sockets and two sets of 2 sockets each. DIMMs in sockets A1
to A8 are assigned to processor 1 and DIMMs in sockets B1 to B4 are assigned to processor 2. 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 those of the second socket are marked black. In the 2-socket set, each release lever is marked white.
