Supermicro MBD-X11SPI-TF-O server motherboard LGA 3647 8 DDR4 slots 1TB max

Single-socket Xeon platform

The Supermicro MBD-X11SPI-TF-O is an ATX server motherboard built around the LGA 3647 socket for single-socket Intel Xeon Scalable processors. It targets builders who need high core counts and large memory capacity in a standard chassis. The Intel C622 chipset provides 10 SATA 6.0 Gb/s ports with RAID 0/1/5/10 support.

Installation notes

The board fits standard ATX mounting holes and uses common 24-pin and 8-pin EPS power connectors. Eight 288-pin DDR4 slots accept ECC RDIMM, LRDIMM or 3DS LRDIMM modules; population rules depend on the specific CPU installed. One PCIe 3.0 x16 slot runs at x16 or x8, a second x16 slot runs at x8, plus one x8 and one x4 slot share bandwidth. The M.2 socket supports both PCIe 3.0 x4 and SATA drives in 2280 or 22110 form factors. Dual 10 GbE RJ45 ports and the Aspeed AST2500 BMC with dedicated LAN simplify remote management.

Pre-purchase checks

Verify that your chosen Xeon Scalable processor is on the vendor's qualified CPU list for this revision. Confirm the memory kit matches the supported DDR4 speeds of 2666, 2400, 2133, 1866 or 1600 MHz and the ECC type required for your capacity target. Ensure the chassis can route power to the EPS connectors and provides airflow over the chipset heatsink. Builders who need more than one CPU socket or more than 10 SATA ports should consider a dual-socket platform.
