Server board for Xeon E3-1200 v5/v6

This ATX motherboard uses the LGA 1151 socket and Intel C236 chipset to support Intel Xeon processor E3-1200 v5 and v6, 6th and 7th Generation Core i3, Celeron and Pentium CPUs. It targets builders assembling rack or tower servers that need ECC memory and dual gigabit LAN in a standard form factor.

Verify CPU cooler clearance

The board fits a standard ATX chassis measuring 30.5cm by 24.4cm. Supported processors have a TDP up to 80W. Four full-size 5V PCI 32-bit slots sit alongside the PCIe slots, so check that any legacy expansion cards do not interfere with cooler mounting or airflow paths.

Dual Intel I210-AT controllers sustain throughput

Two independent gigabit Ethernet ports share no single controller bottleneck, allowing continuous network traffic on both links. The Aspeed AST2400 BMC provides dedicated IPMI LAN access for remote management even when the main CPU is saturated. Six SATA 6.0Gb/s ports with hardware RAID 0, 1, 5, 10 maintain steady storage I/O during prolonged workloads.

Questions about this item

Does the box include a CPU, cooler or memory, or must they be purchased separately?

The motherboard ships alone; you must supply a compatible LGA 1151 processor, DDR4 ECC UDIMM modules and a cooler rated for up to 80 W TDP.

Which memory speed should I select — 2133, 1866 or 1600 MHz — for best performance?

Choose DDR4 2133 MHz ECC UDIMMs; the board runs them at that speed and supports up to 64 GB across the four 288-pin slots.

What does the 64 GB maximum memory figure mean when the board is installed in a working server?

You can populate all four slots with 16 GB DDR4 ECC UDIMMs for a total of 64 GB, which the C236 chipset will address in full.
