reServer before reading this part.
DDR4 Installation
DDR4-3200MT/s has been pre-installed for all versions of reServer but you can also
add a new DDR4 to the other channel or replace the pre-installed one with your
own to expand memory. The dual-channel SO-DIMM slots support DDR4-3200MT/s
up to 64GB in total.
SSD Installation
A NV Me SSD has been pre-installed for all versions of reServer, while, still, the M.2
M-Key 2242/2280(PCIe 3.0 x4) allows you to replace it with the SSD you desire.
