Dell PowerEdge R530xd Owner's Manual

Memory bus operating frequency can be 2133 MT/s, 1866 MT/s, 1600 MT/s, or 1333 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

Your system contains 16 memory sockets split into four sets of four sockets. DIMMs in sockets A1 to A8 are assigned to processor 1 and DIMMs in sockets B1 to B8 are assigned to processor 2. Each 4-socket set is organized into two channels. In each channel of the 4-socket set, the release levers of the first socket are marked white and those of the second socket are marked black.

Figure 1. Memory socket locations

Memory channels are organized as follows:

Processor 1

channel 0: slots A1 and A5

channel 1: slots A2 and A6

channel 2: slots A3 and A7

channel 3: slots A4 and A8

Processor 2

channel 0: slot B1 and B5

channel 1: slot B2 and B6

channel 2: slot B3 and B7

channel 3: slot B4 and B8

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