Memory bus operating frequency can be 1866 MT/s, 2133 MT/s, or 2400 MT/s depending on the following factors:
●
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 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 tabs of the first socket are marked white, the second socket black,
and the third socket green.
