GIGABYTE MS73-HB1 server motherboard dual LGA 4677 DDR5 5600 16 DIMM 6 PCIe 5.0 x16

Dual-socket server motherboard for Xeon Scalable

The GIGABYTE MS73-HB1 is an E-ATX server motherboard that supports two 4th or 5th Generation Intel Xeon Scalable processors in LGA 4677 sockets. It provides sixteen DDR5 288-pin DIMM slots running at 5600 MT/s across eight memory channels for a maximum capacity of 4 TB. Six PCIe 5.0 x16 expansion slots are wired directly from the CPUs.

Suits dual-processor compute and storage nodes

This board fits builders who need two CPUs with up to 270 W TDP each, eight-channel DDR5 memory, and six full-length PCIe 5.0 x16 slots for accelerators or high-speed networking. Twelve SATA 6 Gb/s ports are available through three SlimSAS connectors plus two native SATA ports. Buyers who require a single-socket platform or a different socket type should consider other options.

Six PCIe 5.0 x16 slots from the CPUs

Six x16 slots operate at PCIe 5.0 speeds and are divided between the two processors, delivering the bandwidth needed for modern GPU or storage accelerators. Two M.2 slots accept 2280 or 22110 cards at PCIe 4.0 x4 from CPU 0. Onboard video uses the Aspeed AST2600 controller and dual 1 GbE LAN is provided by Intel I210-AT.
