Micro ATX server board for single-socket Xeon

The Supermicro MBD-X12SPM-TF-O is a Micro ATX motherboard built around the Intel C621A chipset and the LGA 4189 socket for third-generation Intel Xeon Scalable processors up to 270 W TDP. It fits 9.6-by-9.6-inch chassis while delivering eight DDR4-3200 slots with ECC support and a maximum memory capacity of 2 TB.

Suits dense storage or GPU nodes.

This board targets builders who need high core counts, dual 10 GbE ports and multiple PCIe 4.0 lanes in a compact footprint. It will not serve users who require a second processor socket, more than eight memory channels or integrated Wi-Fi.

Eight DDR4-3200 slots with ECC decide capacity

Memory configuration is the primary filter: eight 288-pin slots accept DDR4-3200 RDIMM or LRDIMM modules with ECC, scaling to 2 TB total. If the workload demands more slots, a different form factor or a board with persistent-memory support is required.

Questions about this item

Does this board need a specific CPU cooler mounting for LGA 4189?

The LGA 4189 socket uses the standard square ILM pattern so any cooler rated for that socket will fit the 9.6" x 9.6" Micro ATX layout.

Can I keep my existing DDR4 3200 ECC RDIMMs when moving to this board?

Yes, the eight 288-pin slots accept DDR4 3200 ECC RDIMM or LRDIMM modules up to 2 TB total capacity.

How do I confirm the dual 10 GbE ports are active after first boot?

Check the rear panel link LEDs and verify two 10 Gbps interfaces appear in the OS network manager or BIOS hardware monitor.
