System Memory
Your system supports DDR3 unbuffered ECC DIMMs (ECC UDIMMs) and registered DIMMs (RDIMMs). It supports 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 type (UDIMM or RDIMM)
• 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 processor
The system contains six memory sockets organized into three channels. In each channel, the release levers of the first
socket are marked white and the second socket black.
