The Dell 6NR82 is the replacement system board for the PowerEdge R640 1U rack server. It carries two 2nd Gen Intel Xeon Scalable sockets, 24 DDR4 DIMM slots at 2933 MHz, three PCIe 3.0 slots, a dedicated PERC slot, an rNDC slot and four 1GbE LOM ports. It suits owners repairing or upgrading an existing R640 rather than anyone building a new server, since it fits only that chassis. Buyers rate it highly, and the practical question is whether a used or refurbished board arrives with its CPU sockets and DIMM slots intact.
