System memory
The system supports DDR4 registered DIMMs (RDIMMs) and load reduced DIMMs (LRDIMMs). System memory holds the instructions
that are executed by the processor.
NOTE:
MT/s indicates DIMM speed in MegaTransfers per second.
Memory bus operating frequency can be 2666 MT/s, 2400 MT/s, or 2133 MT/s depending on the following factors:
•
DIMM type (RDIMM or LRDIMM)
•
System profile selected (for example, Performance Optimized, or Custom [can be run at high speed or lower])
•
Maximum supported DIMM frequency of the processors
The PowerEdge FC640 system contains 16 memory sockets split into two sets of 8 sockets, one set per processor. Each 8-socket set is
organized into six channels. In each channel, the release tabs of the first three sockets are marked white, and the fourth socket black.
