Dual-Socket Server Motherboard

The Supermicro MBD-X12DPG-QT6-B is a proprietary server motherboard built for dual Intel Xeon Scalable processors in the LGA 4189 socket. It targets data-centre deployments that need high core counts, large memory capacity and extensive PCIe 4.0 connectivity in a single board.

Suited for dual-CPU compute nodes

This board suits builders assembling dual-socket servers for virtualization, database or high-performance computing clusters that can use 16 DDR4 DIMM slots and six PCIe 4.0 x16 slots. It is not for single-socket chassis, ATX form-factor cases, or workloads that require consumer-grade memory, integrated Wi-Fi or onboard graphics beyond the BMC display output.

Sixteen DDR4 slots with ECC

The board provides 16 x 288-pin DDR4-3200 slots supporting up to 4 TB of 3DS ECC RDIMM or LRDIMM and up to 6 TB of Intel Optane Persistent Memory 200 Series. This density decides whether the platform fits memory-intensive workloads or if a board with fewer slots is sufficient.

Highlights

  • Dual 3rd Gen Intel Xeon Scalable processors supported via two LGA 4189 sockets
  • 16 DDR4 3200 slots with ECC enable up to 6 TB Optane persistent memory
  • Six PCIe 4.0 x16 plus one PCIe 4.0 x8 provide high-bandwidth expansion
  • Dual 10 Gbps Intel X550 LAN ports deliver fast server networking
  • Two M.2 PCIe 4.0 x4 slots with RAID 0/1 plus ten SATA 6.0 Gb/s ports

Questions about this item

Will the board handle two 270 W Xeon CPUs continuously without throttling?

The motherboard is rated for dual LGA 4189 processors up to 270 W TDP each, so sustained full-load operation stays within the designed thermal envelope.

How loud and hot does the ASPEED AST2600 BMC and dual 10 GbE Intel X550 run during 24/7 operation?

The AST2600 BMC and twin Intel X550 10 GbE controllers are low-power management and networking chips; they add minimal heat and no audible noise, leaving system thermals and acoustics to the CPU coolers and chassis fans you install.

Which DDR4 DIMMs and M.2 drives must I already own to populate this board?

You need 288-pin DDR4-3200 ECC RDIMM or 3DS ECC LRDIMM modules (up to 16 slots) and M-key M.2 drives in 2242, 2260, 2280 or 22110 form factors for the two PCIe 4.0 x4 M.2 slots.
