Memory
The Dell PowerEdge R630 supports DDR4 registered DIMMs (RDIMMs), and load-reduced DIMMs (LRDIMMs).
NOTE: MT/s indicates DIMM speed in MegaTransfers per second.
Memory bus operating frequency can be 1866 MT/s, 2133 or 2400 MT/s depending on:
● DIMM type (RDIMM or LRDIMM).
● 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 24 memory sockets split into two 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 and DIMMs in sockets B1 to B12 are assigned to processor
2.
Memory channels are organized as follows:
Processor 1
Channel 0: slots A1, A5, and A9
Channel 1: slots A2, A6, and A10
Channel 2: slots A3, A7, and A11
Channel 3: slots A4, A8, and A12
