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 rst 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 r
st slot of each memory channel. The rst slot of each channel can be identied as the DIMM slots with white latches.
For example, 64 GB system memory capacity can be divided into 8 x 8 GB DIMM slots.
