* - Maximum DIMM capacity of 128 GB will be available at a later time.
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.
