Server motherboard for Xeon E3 and Core 6th/7th Gen

The Supermicro MBD-X11SAT-F-O is an ATX server board built around the Intel C236 chipset and a single LGA 1151 socket. It targets builders assembling entry-level workstations or small business servers that need ECC memory support and multiple expansion slots. The board ships new in retail packaging.

Four DDR4 slots with 64 GB maximum

Four 288-pin DIMM sockets accept unbuffered ECC or non-ECC DDR4 at 2133, 1866 or 1600 MHz, capping total capacity at 64 GB. This memory ceiling is the primary constraint; systems requiring more RAM must choose a different platform. The board does not support registered or load-reduced modules.

Passive chipset cooling with 95 W CPU limit

The C236 PCH is cooled without a fan, so chassis airflow must cover the chipset heatsink. Processor power draw is rated up to 95 W TDP; higher-wattage CPUs are not supported. Two onboard Gigabit LAN controllers and the ASPEED AST2400 BMC add minimal heat under typical server loads.

Questions about this item

What does the 64 GB DDR4 limit mean for a workstation build?

The board has four 288-pin slots and supports up to 64 GB of unbuffered ECC or non-ECC DDR4 at 2133 MHz, so you can populate all four slots with 16 GB modules to reach the maximum capacity.

How do the PCIe 3.0 x16 slots share bandwidth?

The three x16 slots run at either 16/NA/16 or 16/8/8 depending on how many are occupied, while the x1-in-x4 slot and the 5 V PCI slot operate independently.

What chassis space and power connectors does the ATX board need?

It measures 30.48 cm by 24.38 cm, fits standard ATX cases, and the CPU socket is rated for processors up to 95 W TDP, so plan cooling and power delivery accordingly.
