System memory
Your system supports DDR4 registered DIMMs (RDIMMs) and load reduced DIMMs (LRDIMMs). 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:
● Number of DIMMs populated per channel
● System profile selected (for example, Performance Optimized, Custom, or Dense Configuration Optimized)
● Maximum supported DIMM frequency of the processors
The system contains 24 memory sockets split into two sets of 12 sockets, one set per processor. Each 12-socket set is
organized into four channels. In each channel, the release levers of the first socket are marked white, the second socket black,
and the third socket green.
