Our take on the Dell EMC PowerEdge R740xd Server Motherboard

This is the system board for the Dell PowerEdge R740xd rack server, part YNX56 (0YNX56). It has two LGA3647 sockets for Intel Xeon Scalable processors and 24 DDR4 DIMM slots, which is the memory capacity the R740xd is built around. It suits owners repairing or expanding an existing R740xd, not anyone building a general-purpose PC: the board fits that chassis and its risers, not a standard case. Compared with newer Dell platforms it uses the first and second Xeon Scalable generations and DDR4, so it is a replacement part rather than an upgrade path.

Pros
  • Two LGA3647 sockets support dual Xeon Scalable CPUs
  • 24 DDR4 DIMM slots give the R740xd its large memory ceiling
  • Exact Dell part YNX56, so it matches the R740xd chassis and risers
  • Available as a direct replacement rather than a whole server
Cons
  • Fits only the R740xd; not a standard ATX board
  • LGA3647 and DDR4 limit it to older Xeon Scalable generations
  • No CPU, memory, heatsinks or risers included
  • Refurbished units may show wear or bent socket pins

Questions and answers

Which servers does this board fit?
It is the system board for the Dell PowerEdge R740xd. It is shaped for that chassis and its risers, so it does not drop into a standard PC case or another Dell model.
Which CPUs does it support?
It has two LGA3647 sockets for Intel Xeon Scalable processors. Check that your chips are on Dell's supported list for the R740xd before fitting them.
How much memory can it take?
It has 24 DDR4 DIMM slots, the full memory layout of the R740xd. Memory modules are not included.
Is this the same as the R740 board?
No. The R740xd is a deeper storage-focused chassis, and its board and riser layout differ from the plain R740. Use the YNX56 part for the R740xd.
What is in the box?
The motherboard only. Processors, heatsinks, memory, risers and cables are not included unless stated with the unit you buy.
Can I replace the board myself?
It is a full server teardown: CPUs, heatsinks, memory, risers and cabling all move over. Dell's R740xd service manual covers the procedure, and a torque screwdriver is needed for the LGA3647 heatsinks.
Where is the Dell EMC PowerEdge R740xd Server Motherboard cheapest?
At Alo Tech Solutions, for $336.53, as of our latest check.
