System Memory
Your system supports DDR3 registered DIMMs (RDIMMs) and meets the DDR3 and DDR3L voltage specifications.
NOTE: MT/s indicates DIMM speed in MegaTransfers per second.
Memory bus operating frequency can be 1600 MT/s, 1333 MT/s, 1066 MT/s, or 800 MT/s depending on:
•
DIMM configuration (number of ranks)
•
maximum frequency of the DIMMs
•
number of DIMMs populated per channel
•
DIMM operating voltage
•
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.
