Our take on the 6DKY5 System Board Motherboard

The Dell 6DKY5 is the system board for the PowerEdge R640 rack server. It takes two 2nd Gen Intel Xeon Scalable processors on LGA3647 sockets and holds 24 DDR4 DIMMs, up to 2933 MHz ECC RDIMM or LRDIMM. Three PCIe 3.0 slots, a dedicated PERC slot, an rNDC slot and four 1GbE LOM ports cover storage and network expansion, with room for up to three single-width GPUs. It suits owners repairing or upgrading an existing R640 rather than anyone building a new server, since it fits only that chassis and generation.

Pros
  • Two LGA3647 sockets for dual 2nd Gen Xeon Scalable CPUs
  • 24 DIMM slots support large ECC DDR4 memory builds at 2933 MHz
  • Dedicated PERC and rNDC slots keep PCIe slots free
  • Four built-in 1GbE LOM ports
  • Fits up to three single-width GPUs
Cons
  • Fits only the PowerEdge R640 chassis
  • LGA3647 limits it to Xeon Scalable, not newer sockets
  • Only three PCIe 3.0 slots
  • 1GbE LOM is slow by current server standards
