  • Supports 4th Gen Xeon Scalable CPUs up to 350W TDP
  • Intel C741 chipset enables enterprise server features
  • 8 DDR5 slots accept up to 2TB 3DS ECC RDIMM at 4800MT/s

  • Eight PCIe 5.0 NVMe x4 ports plus two M.2 PCIe 4.0 x2 slots

Single-socket Xeon server board

The Supermicro MBD-X13SEM-TF-O is an mATX server motherboard built for the LGA-4677 socket. It accepts a single 4th Gen Intel Xeon Scalable processor with a thermal design power of up to 350W. The Intel C741 chipset provides the platform foundation for dense compute or storage nodes.

Suited for high-density memory and fast storage

This board suits builders who need up to 2TB of DDR5-4800 3DS ECC RDIMM across eight slots running at one DIMM per channel. It also provides eight PCIe 5.0 x4 NVMe internal ports plus two M.2 slots for 2280 or 22110 modules. Buyers who require multiple processor sockets or more than three PCIe 5.0 expansion slots should look at larger form-factor alternatives.

One CPU socket limits scaling

The single LGA-4677 socket means the system tops out at one Xeon processor, capping core count and memory channels at the single-socket maximum. Dual-socket or quad-socket workloads cannot be supported on this platform.

Questions about this item

Should I choose the 4th Gen Xeon with a 350W TDP or a lower-power model for this board?

The LGA-4677 socket supports up to 350W TDP, so select a processor whose rated power matches your cooling and power-budget limits.

What does the DDR5-4800MT/s rating mean once the memory is installed?

Each of the eight DIMM slots runs at 4800 MT/s with one DIMM per channel, delivering up to 2TB of 3DS ECC RDIMM capacity.

How many NVMe drives can the PCIe 5.0 x4 ports actually support?

Eight internal PCIe 5.0 x4 NVMe ports are available, each providing a full x4 link to a drive.
