GIGABYTE packed the C622 chipset motherboard with all sort of awesome features. To start with, it’s equipped with 6 RJ45 ports for 1GbE, 10GbE, remote management, and serial connections. There’s also plenty of storage options with a total of 14 SATA3 ports (2 with DOM support), two U.2 ports via two SlimSAS connectors, and dual M.2 22110 connectors. And that’s just what’s onboard. You can expand it with more storage drives, graphics cards, or other add-in cards through the six PCIe slots.
As mentioned, MD71-HB0 has two LGA3647 sockets for a dual CPU setup. They support TDPs up to 205W and feature the narrow ILM mount. There are 16 DDR4 DIMM slots with 6-channel memory architecture. The memory sockets support up to 64GB RDIMM or LRDIMM with a speed up to 2666MHz. Combining it all is an Intel C622 Express chipset.

Expansion Slots
The basic idea of all motherboards is the ability to expand the functionality. GIGABYTE’s MD71-HB0 has three PCIe Gen3 x16 and three PCIe Gen3 x8 full-size slots. Two x16 and one x8 are controlled by one CPU while one of each is controlled by the second CPU. The last x8 slot is controlled by the C622 chipset.
M.2 slots are also technically PCIe slots. The board comes with two M-key slots which are PCIe Gen3 x4 each. They support M.2 modules with up to 32Gbps and a size up to 22110. These two are controlled by the first CPU. The second CPU controls the two U.2 ports with SlimSAS connector. These feature the same PCIe Gen3 x4 speed per port.
