Supermicro X13SEI-F LGA 4677 Server Motherboard

This ATX server motherboard supports a single 4th or 5th Gen Intel Xeon Scalable processor in an LGA 4677 socket with up to 350W TDP. It provides eight DDR5 DIMM slots for ECC registered memory up to 256GB capacity. The board includes ten SATA 6.0Gb/s ports, dual Intel I210 1GbE LAN, and an Aspeed AST2600 video controller.

Suits single-socket Xeon builds with high SATA count

Builders needing one processor, up to 256GB DDR5 ECC memory, and ten SATA ports for storage arrays will match this platform. It also offers two PCIe 5.0 x16 slots, three PCIe 5.0 x8 slots, two MCIO connectors for four NVMe SSDs, and two M.2 PCIe 5.0 x4 slots. Buyers requiring dual-socket support, more than 256GB memory, or 10GbE networking should consider other options.

Eight DDR5 slots capped at 256GB maximum capacity

The memory subsystem accepts DDR5-4800MHz or DDR5-5600MT/s 3DS ECC RDIMMs across eight slots, but the total installed capacity cannot exceed 256GB. This limit defines the maximum RAM configuration for any single-processor deployment on this board.

Questions about this item

What case and cooler clearance does the 12" x 10" ATX board with LGA 4677 socket need?

The board fits any ATX chassis measuring at least 12" x 10"; choose a cooler rated for LGA 4677 with up to 350W TDP capacity and verify it clears the eight DIMM slots and two MCIO connectors.

Which BIOS setting is often missed when installing 4800MT/s DDR5 ECC RDIMMs in all eight slots?

After seating all eight modules, enter BIOS and enable the DDR5-4800 frequency profile; the board defaults to a lower speed until the profile is selected.

Which onboard component typically requires replacement after several years of continuous operation?

The Aspeed AST2600 BMC chip manages remote access; if IPMI becomes unresponsive, the chip or its dedicated firmware storage may need service.
