LGA 4677 workstation motherboard

The Supermicro MBD-X13SWA-TF-O is a single-socket server board built around the Intel W790 chipset for Xeon W-3400, W-2400, W-3500 and W-2500 processors. It delivers sixteen DDR5 288-pin slots supporting up to 2TB of ECC registered memory at 4800 MT/s. Six PCIe 5.0 x16 slots provide high-bandwidth expansion for GPUs or accelerators. Dual LAN includes 10GbE via Marvell AQC113C and 1GbE via Intel I210-AT.

Suited for memory-intensive compute.

This board targets workstations and servers that need large memory capacity, multiple high-speed GPUs and fast local storage. Builders limited to ATX cases or modest power budgets should look elsewhere, as the 385W CPU support and six full-length slots demand robust cooling and a compatible E-ATX enclosure. Systems requiring more than two onboard 10GbE ports will need add-in networking cards.

Sixteen DDR5 slots define maximum capacity

The sixteen 288-pin DDR5 slots set the hard limit of 2TB with 3DS ECC RDIMMs or 1TB with standard ECC RDIMMs on W-3400 and W-3500 CPUs. Populating all channels at 1DPC runs at 4800 MT/s; 2DPC drops to 4400 MT/s. Verify your processor series and memory kit density against these limits before purchase.
