DIMM type (RDIMM or LRDIMM)
Number of DIMMs populated per channel
System prole selected (for example, Performance Optimized, or Custom [can be run at high speed or lower])
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 six
channels. In each channel, the release tabs of the rst socket are marked white, and the second socket black.
