System memory
The system supports DDR4 registered DIMM (RDIMMs) slots. System memory holds the instructions that are executed by the
processor.
Memory bus operating frequency is 3200 MT/s or 2666 MT/s depending on the following factors:
● DIMM type (RDIMM)
● Number of DIMM slots populated per channel
● System profile selected (for example, Performance Optimized, or Custom [can be run at high speed or lower])
● Maximum supported DIMM frequency of the processors
NOTE: MT/s indicates DIMM speed in MegaTransfers per second.
Your system contains 24 memory sockets split into two sets of 12 sockets, one set per processor. Each 12-socket set is
organized into six channels. In each channel, the release tabs of the first socket are marked white, and the second socket black.
