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 1333 MT/s, 1600 MT/s, 1866 MT/s, or 2133 MT/s depending on
the following factors:
• DIMM type (RDIMM)
• 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 16 memory sockets split into two sets of 8 sockets, one set per processor. Each 8-
socket set is organized into four channels. In each channel, the release levers of the first socket are
marked white and the second socket black.
NOTE: DIMMs in sockets A1 to A8 are assigned to processor 1 and DIMMs in sockets B1 to B8 are
assigned to processor 2.
