Your system contains 32 memory sockets split into two sets of 16 sockets, one set per processor. Each 16-socket set is organized into eight
channels. In each channel, the release tabs of the first socket are marked white, and the second socket black.
NOTE:
For optimal performance, it is recommended to populate one DIMM per channel with DDR4, 2666 MT/s memory modules
on the first slot of each memory channel. The first slot of each channel can be identified as the DIMM slots with white latches.
For example, 64 GB system memory capacity can be divided into 8 x 8 GB DIMM slots.
