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 either 2400 MT/s, 2133 MT/s, and 1866 MT/s depending on the:
• DIMM type (RDIMM or LRDIMM)
• DIMM configuration (number of ranks)
• Maximum frequency of the DIMMs
• 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
Your system contains 48 memory sockets split into four 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, B1 to B12 to processor 2, C1 to C12
to processor 3, and D1 to D12 to processor 4.
