Socket P+ server board

The Supermicro MBD-X12SPL-F is an ATX server motherboard built for single-socket 3rd Gen Intel Xeon Scalable processors up to 270 W TDP. It targets system integrators and IT teams deploying compute or storage nodes that need high memory capacity in a standard chassis footprint.

Eight DDR4 slots scale to 2 TB

Eight 288-pin slots run DDR4-3200 with ECC, supporting 3DS RDIMM, 3DS LRDIMM and Intel Optane Persistent Memory up to 2 TB total. The board runs out of headroom when workloads demand more than eight DIMM slots or memory speeds beyond the 3200 MT/s ceiling.

Expansion mix covers GPUs, NICs and fast boot

One PCIe 4.0 x16, two PCIe 4.0 x8, one PCIe 4.0 x8 wired in an x16 slot and three PCIe 3.0 x8 slots provide lanes for accelerators and networking cards. Ten SATA 6 Gb/s ports with RAID 0/1/5/10 and a single M.2 M-key slot accepting 2280 or 22110 drives on SATA or PCIe 3.0 x4 handle boot and bulk storage. Rear I/O supplies dual gigabit LAN, VGA, two USB 3.2 Gen1, two USB 2.0 and a COM header; internal headers add four USB 2.0, two USB 3.2 Gen1 and one Type-A port plus a TPM header.

Questions about this item

Will my existing DDR4-3200 3DS ECC RDIMMs work in the 8 slots of this MBD-X12SPL-F?

Yes, the board accepts up to 2 TB of DDR4-3200 3DS ECC RDIMM or LRDIMM across its 8 x 288-pin slots.

How can I confirm the Aspeed AST2600 video and dual Intel I210 Gigabit LAN are active after first boot?

Connect a monitor to the VGA port and cables to both RJ45 ports; the BIOS splash on screen and link lights on the two LAN jacks show they are working.

Which cables or modules must I add to use the 10 SATA 6.0 Gb/s ports and the M.2 2280/22110 M-Key slot?

You need SATA data cables for each drive you attach to the 10 onboard ports and a M.2 2280 or 22110 M-Key SSD for the M.2 slot.
