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 oper a ting fr equenc y can be 2 400 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.
NOTE: DIMMs in sockets A1 to A12 are assigned to processor 1 and DIMMs in sockets B1 to B12 are assigned to processor
2.
The following table shows the memory populations and operating frequencies for the supported configurations.
