System memory
The Dell EMC PowerEdge R7425 supports DDR4 registered DIMM (RDIMMs) slots and load reduced DIMM (LRDIMMs) slots.
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)
• Number of DIMM slots populated per channel
• System prole selected (for example, Performance Optimized, or Custom [can be run at high speed or lower])
• Maximum supported DIMM frequency of the processors
Your system contains 32 memory sockets split into two sets of 16 sockets, one set per processor. Each 16-socket set is organized
into eight channels. In each channel, the release tabs of the rst socket are marked white, and the second socket black.
