Micro ATX server board for LGA 1200 Xeon

This Micro ATX motherboard fits single-socket LGA 1200 processors from the Intel Xeon E-2300 series and 10th Generation Intel Pentium line. The Intel C256 chipset provides four DDR4 3200 slots with ECC support, making the board suited for entry-level workstations and small-form-factor servers that need reliable memory integrity.

Memory capacity tops out at 128 GB across four slots

Four 288-pin DIMM sockets accept up to 128 GB of DDR4 3200 ECC UDIMM, giving headroom for multi-VM hosts or memory-heavy databases. Expansion stops at one PCIe 4.0 x16 slot plus two x8 physical slots wired as one PCIe 4.0 x4 and one PCIe 3.0 x4, so only a single full-width add-in card and two low-profile cards can be accommodated.

Quad 1 GbE and ASPEED BMC simplify remote management

Four rear RJ45 ports driven by Intel I210 controllers deliver segregated or bonded 1 GbE links without extra NICs. The ASPEED AST2600 BMC with dedicated VGA and COM ports enables headless IPMI control, while storage connectivity covers eight SATA 6.0 Gb/s ports and one M.2 M-key slot supporting 2280 and 22110 drives on a PCIe 3.0 x4 interface.

Questions about this item

Will my existing DDR4 3200 ECC UDIMMs work in the four 288-pin slots on this board?

Yes, the board accepts up to 128 GB of DDR4 3200 ECC UDIMM across four 288-pin slots, so your current modules are compatible.

How can I confirm the ASPEED AST2600 BMC and the four RJ45 LAN ports are operating after assembly?

Connect a monitor to the rear VGA port; the AST2600 BMC will display its boot screen, and all four RJ45 ports show link LEDs when cables are plugged in.

Which cables or add-in cards must I purchase separately to use the eight SATA 6.0 Gb/s ports and the M.2 2280/22110 slot?

You need SATA data cables for each drive you connect to the eight SATA ports and an M.2 M-key module (2280 or 22110) for the PCIe 3.0 x4 slot; the board includes the rear I/O shield.
