Our take on the CRT1G System Board Motherboard Dell PowerEdge R640

This is the replacement system board for the Dell PowerEdge R640, a 1U rack server. It carries two 2nd Gen Intel Xeon Scalable sockets, 24 DDR4 DIMM slots running up to 2933 MHz, three PCIe 3.0 slots, a dedicated PERC slot, an rNDC slot and four 1GbE LOM ports. It is a service part for owners repairing or upgrading an existing R640, not a board for a new build. Against buying a whole replacement server, it keeps the existing chassis, drives and power supplies in use.
