Supermicro MBD-X12SPM-TF-O server motherboard

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.
