Dell PowerEdge M830 Owner's Manual

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.
Figure 1. Memory socket locations
This figure shows memory socket locations.

Memory channels are organized as follows:

Processor 1
channel 0: memory sockets A1, A5, and A9
channel 1: memory sockets A2, A6, and A10
channel 2: memory sockets A3, A7, and A11
channel 3: memory sockets A4, A8, and A12
Processor 2
channel 0: memory sockets B1, B5, and B9
channel 1: memory sockets B2, B6, and B10
channel 2: memory sockets B3, B7, and B11
channel 3: memory sockets B4, B8, and B12
Processor 3
channel 0: memory sockets C1, C5, and C9
channel 1: memory sockets C2, C6, and C10
channel 2: memory sockets C3, C7, and C11
channel 3: memory sockets C4, C8, and C12
Processor 4
channel 0: memory sockets D1, D5, and D9
channel 1: memory sockets D2, D6, and D10
channel 2: memory sockets D3, D7, and D11
channel 3: memory sockets D4, D8, and D12

The following table shows the memory populations and operating frequencies for the supported configurations.
