Dual-Socket LGA-4189 Server Board for 3rd Gen Xeon

The Supermicro MBD-X12DPL-NT6-O is a dual-socket ATX motherboard built around the Intel C621A chipset. It supports two 3rd Gen Intel Xeon Scalable processors with a maximum TDP of 185 W each and up to 11.2 GT/s UPI interconnect speed. The board provides eight 288-pin DDR4-3200 slots for up to 2 TB of ECC RDIMM or 3DS LRDIMM memory.

Suits High-Density Compute and Storage Nodes

This platform targets builders who need dual-processor performance, 12 SATA3 ports with RAID 0, 1, 5, 10, and dual 10 GbE LAN from the Intel X550 controller. It is not intended for single-socket workstations, consumer desktop CPUs, or systems that require more than four PCIe 4.0 x16 slots or integrated graphics beyond the ASPEED AST2600 BMC video output.

The Deciding Spec Is Dual LGA-4189

The combination of two LGA-4189 sockets and twelve 6 Gbps SATA ports driven by the C621A chipset determines whether this board fits the chassis and storage layout. If the deployment calls for a single socket, fewer drive connections, or a different memory generation, another motherboard must be selected.

Questions about this item

What is the maximum CPU TDP the board can cool continuously?

The board supports processors up to 185 W TDP per socket, so sustained loads are limited by that thermal ceiling.

What heat and noise should I expect from the onboard 10 GbE controller during all-day operation?

The Intel X550 10GBase-T controller runs at 10 Gbps; its thermal output and fan noise depend on your chassis airflow and system fan curves.

Which processors and memory must I already have to populate this motherboard?

You need two 3rd Gen Intel Xeon Scalable CPUs for the dual LGA-4189 sockets and DDR4-3200 RDIMM or 3DS ECC LRDIMM modules for the eight 288-pin slots.
