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
Processor 2
Channel 0: slots B1, B5, and B9
Channel 1: slots B2, B6, and B10
Channel 2: slots B3, B7, and B11
Channel 3: slots B4, B8, and B12
