Dual-Socket Xeon 6 Server Board

The GIGABYTE MS74-HB0 is an Extended ATX server motherboard built for Intel Xeon 6700 and 6500 series processors in LGA 4710 sockets. It supports a single CPU with a thermal design power up to 350W. Sixteen DDR5 RDIMM slots run in eight channels at up to 6400 MT/s, while MRDIMM modules reach 8000 MT/s. Six PCIe 5.0 x16 expansion slots and two M.2 connectors with PCIe Gen5 x4 provide high-bandwidth I/O for accelerators and storage.

Suited for Compute-Dense Deployments

This board fits workloads that need many cores, large memory capacity and multiple 10GbE links in a dual-socket layout. It is not for builders who need a second processor socket, as the specification lists support for one CPU only. Buyers who require integrated Wi-Fi, Bluetooth or consumer audio features should look elsewhere. Systems needing more than sixteen DIMM slots or additional PCIe lanes beyond the six x16 slots will not be served by this platform.

Straightforward Rack Integration

Installation follows standard E-ATX mounting patterns with a 24-pin ATX connector, two 8-pin and two 6-pin 12V CPU power headers. Two dedicated CPU fan headers and five system fan headers simplify cooling wiring. The most common issue is forgetting to populate all eight memory channels for full bandwidth, and overlooking the six 12V power connectors when using high-TDP processors. Ensure the chassis accommodates the extended ATX dimensions before ordering.

Questions about this item

Do I need Intel Xeon 6700 or 6500 series processors with LGA 4710 socket to use this board?

Yes, the board supports one Intel Xeon 6700 or 6500 series processor in an LGA 4710 socket with a TDP up to 350W.

Can I keep my existing PCIe 4.0 add-in cards when moving to the six PCIe 5.0 x16 slots?

PCIe 4.0 cards will operate at Gen 4 speeds in the six PCIe 5.0 x16 slots, which are wired from the CPU.

How can I confirm the DDR5 memory is running at 6400 MT/s or 8000 MT/s after assembly?

Check the BIOS memory information screen or the operating system memory report for the configured data rate.
