Single-socket Xeon board for dense compute

The Supermicro MBD-X13SEI-TF-O is an ATX server motherboard built around a single LGA 4677 socket for 4th Gen Intel Xeon Scalable processors with a thermal design power of up to 350W. Eight DDR5 DIMM slots support up to 2TB of 3DS ECC RDIMM at 4800MT/s. Ten SATA 6.0Gb/s ports and dual 10Gbps Intel X550 LAN provide storage and network throughput.

Standard ATX layout with high-power CPU cooling

The 12" x 10" form factor fits regular ATX server chassis and uses familiar mounting holes. Installing a 350W TDP processor demands a server-grade heatsink or liquid block rated for that heat load; standard desktop coolers will not suffice. MCIO and M.2 connectors sit near the board edge, so cable routing should be planned before the board is secured.

Verify chassis clearance and power delivery

Confirm the case can accommodate a 350W TDP cooler and that the power supply delivers sufficient 12V current for the CPU and up to four NVMe SSDs via the two MCIO x8 and two M.2 slots. Memory must be DDR5 3DS ECC RDIMM; other DDR generations will not fit or function.

Questions about this item

How can I verify the board is operating correctly after installing a 4th Gen Intel Xeon processor and DDR5 memory?

The board will complete POST, display the BIOS screen, and report the installed CPU and memory capacity and speed in the system information.

What is included with the motherboard and which components must be purchased separately?

The motherboard itself is supplied; a compatible LGA 4677 Xeon processor, DDR5 ECC RDIMM modules, storage drives and a suitable ATX power supply must be bought separately.

Which memory capacity should I choose for the eight DIMM slots — 256 GB or the full 2 TB?

Standard RDIMMs support up to 256 GB total at 4800 MT/s; 3DS RDIMMs are required to reach the 2 TB maximum across all eight slots.
