Today ASRock Rack is announcing a new series of embedded motherboards based on the Intel Atom C3000 series. The ASRock Rack C3000D4 series has three models at launch. We expect that there could be additional options based on customer demand as ASRock has designed the motherboard to have flexibility for embedded customers. We reviewed the company’s previous generation C2000 series motherboard, in our ASRock Rack C2750D4I Review. This time around, ASRock Rack is utilizing parts with embedded QuickAssist Technology.

ASRock Rack C3000D4 Series at Launch

We do not have finalized pictures, and are unsure of what we can show, but we wanted to provide a few details around the motherboards we received.

ASRock Rack C3758D4U-2TP

The ASRock Rack C3758D4U-2TP combines the 8-core 24W TDP Intel Atom C3758 24W TDP CPU with a mATX form factor to provide expanded capacbilities. For example, there are two Marvell 9172 SATA III controllers for 4 port 6.0gbps SATA III. Networking includes 2x RJ45 via the Intel X557 10Gbase-T NIC. Expansion slots can be either both a PCIe 3.0 x8 and PCIe 3.0 x4 slot or the PCIe 3.0 x8 slot can be used for an optional SAS 3008 controller (pictured.) We also note that although we did not get the SFP+ version details, it appears as the marketing photo we received (above) is has the 2OP8R in its SKU which seems to indicate 2x SFP+ 10GbE along with a SAS 3008 controller.

ASRock Rack C3758D4I-4L

The mITX ASRock Rack C3758D4I-4L will ship with the Intel Atom C3758 8 core 24W TDP CPU. ASRock Rack will have up to 13x SATA III devices, 8 of which will use Mini-SAS HD (SFF-8643) connectors. ASRock is enabling the HSIO lane switching via BIOS so one can use HSIO lanes for either SATA or PCIe connections. This motherboard will also have up to 4x DDR4-2400 DIMM channels and quad LAN.

ASRock Rack C3558D4I-4L

Also, a mITX form factor, ASRock Rack C3558D4I-4L is similar to the C3758D4I-4L, however, utilizes the Intel Atom C3558 4 core 16W TDP CPU. ASRock Rack will have up to 5x SATA III devices, 4 of which will use a Mini-SAS HD (SFF-8643) connector. ASRock is enabling the HSIO lane switching via BIOS so one can use HSIO lanes for either SATA or PCIe connections. This motherboard will also have up to 4x DDR4-2133 DIMM channels and quad LAN. The I/O and DDR4 changes are being driven by the lower number of HSIO lanes on the Intel Atom C3558 SoC.

Final Words

We will be bringing you more on these boards as they are put into production. We expect them to be in the market by the end of September 2017


  1. Hello Cliff,

    Are there any chances of seeing ASRock Rack releasing the motherboard in the picture (top bin Atom CPU, SAS 3008 controller, and SFP+ modules), or another manufacturer like Supermicro for a comparable configuration? I haven’t seen much activity since the initial flurry of new boards at Supermicro
    I am wondering if there is any demand for this type of configuration.


  2. Announced and released are two different things. We have reviews of several Supermicro, Gigabyte, and Tyan Atom C3000 platforms, but we still do not have an ASRock Rack platform in the lab.
