GIGABYTE MD72-HB3 server motherboard, Dual Socket P+, 16 DDR4 3200 slots, 256GB max

Dual Socket P+ Xeon platform

The GIGABYTE MD72-HB3 is an Extended ATX server motherboard built for dual 3rd Generation Intel Xeon Scalable processors. It provides sixteen DDR4 3200 slots with a maximum capacity of 256GB and supports Intel Optane Persistent Memory 200 series. Four PCIe 4.0 x16 slots and three SlimSAS connectors give high-throughput paths for GPUs, accelerators and dense storage arrays.

Power and chassis clearance checks

Verify that your chassis accepts the Extended ATX form factor and can route the 24-pin ATX, two 8-pin ATX 12V and one 6-pin PCIe power connectors. Confirm that your CPU coolers match the Socket P+ mounting pattern and that the power supply delivers sufficient current for two processors rated up to 270W each. Ensure back-panel cut-outs align with the two USB 3.0, VGA, COM, dual RJ45, dedicated management LAN and ID button ports.

Thermal, noise and power profile

With two CPUs installed the board draws power through three dedicated 12V connectors plus the main ATX feed, so VRM temperatures scale with the 105-270W processor range. Eight memory channels per socket mean fully populated DIMM slots increase airflow demand across the sixteen slots. The Aspeed AST2600 management controller and dual Intel I210-AT 1GbE ports add minimal heat, while fan headers for both CPUs and system zones allow tuned cooling curves for quieter operation under typical loads.
