Server motherboard for Xeon E3-1200 v5/v6

The ASRock Rack C236 WS is an ATX server motherboard built around the Intel C236 chipset and the LGA 1151 socket. It supports Intel Xeon E3-1200 v5 and v6 series processors, plus selected Core i7, i5, i3, Pentium and Celeron CPUs from the 6th and 7th generations. Four 288-pin DDR4 slots run in dual-channel mode up to 64 GB with ECC or non-ECC UDIMMs. The board measures 12 inches by 9.6 inches and fits standard ATX server chassis.

Suited for storage-focused builds.

This motherboard suits builders who need eight SATA 6.0 Gb/s ports with hardware RAID 0, 1, 5 and 10 for local storage arrays. Dual Intel gigabit LAN ports (i210 and i219) provide redundant network links. Two full-length PCIe 3.0 x16 slots, one x8 slot and two x1 slots accommodate RAID controllers, NICs or GPU compute cards. Two legacy PCI slots remain for older expansion cards. Buyers who need more than 64 GB of memory or more than two x16 electrical links should look at platforms with higher core-count CPUs and larger DIMM capacities.

LGA 1151 socket decides CPU compatibility

The LGA 1151 socket limits the board to the processors listed in the official support list, including Xeon E3-1200 v5 and v6 chips and specific 6th- and 7th-generation Core, Pentium and Celeron models. BIOS version 2.0 or above is required for certain v4 series Xeons. DDR4 2400 MT/s is only available when a v6 Xeon is installed; otherwise the maximum supported speed is 2133 MT/s. Non-ECC UDIMMs are supported only with client operating systems.

Questions about this item

How much power does the Intel C236 chipset on this board draw under continuous server load?

The Intel C236 chipset is a low-power platform controller hub; its thermal design power is small compared with the Xeon E3-1200 v5/v6 processors this board supports, so total system draw is dominated by the chosen CPU and memory configuration.

Which processor and memory must I already have to populate the LGA 1151 socket and the four 288-pin DDR4 slots?

You need an Intel Xeon E3-1200 v5 or v6 series CPU (or a listed Core i7/i5/i3, Pentium or Celeron) plus DDR4 2400/2133/1866/1600 ECC or non-ECC UDIMMs up to 64 GB total in dual-channel mode.

Will my existing PCI add-in cards fit the two PCI slots and the PCIe 3.0 x1, x8 and x16 slots on this motherboard?

Yes — the board provides two legacy PCI slots, two PCIe 3.0 x1 slots, one PCIe 3.0 x8 slot and two PCIe 3.0 x16 slots that can run at x16 or x8/x8, so older PCI and PCIe cards install directly.
