This week Colorful has introduced a uniquely designed motherboard, created specifically for the professional miner. One of the first things most will notice is this doesn’t look like most motherboards we see on the market. Instead of conforming to any particular form factor, the C.J1900A-BTC Plus V20 breaks that mold and gives us a markedly rectangular shaped board with a total of nine full-length PCIe slots. Eight of the slots can be used for installing mining graphics card of choice while the blue slot in the middle is where the Celeron J1900 SoC resides on its own PCIe card. The SoC itself has a DDR3 SO-DIMM slot, a mSATA slot, and regular SATA for storage; it also contains the board’s connectivity like networking, USB, and video output.

With the price of a single bitcoin breaking the $7000 barrier recently, GPU mining has not lost its draw of profitability, especially with alt-coins. We have seen a few Intel board partners come out with purpose made mining motherboards cramming in well over a dozen PCIe x1 slots on a single ATX form factor board in order to reduce the per-system cost of mining infrastructure. The lower the outgoing cost, the quicker miners are able to get their money back.

To that end, Colorful introduced the C.J1900A-BTC Plus V20 with enough room for eight cards without the use of riser cables. The board offers double slot spacing between each slot and looks to be around 16-inches in length and almost 7-inches wide throwing aside any standard form factor out of the way. Power is delivered to the cards through a total of sixteen 6-pin PCIe power connectors with eight located on one end and eight around each of the GPU slots.

According to the specifications, the Celeron J1900 SoC is based on Intel's Bay Trail and is a quad-core processor with a base frequency of 2.00 GHz, a burst frequency of 2.42 GHz, and fits within a 10W TDP. It has one DDR3L SO-DIMM slot supporting DDR3L 1066/1333MHz. Graphics duties are handled by integrated GPU (HD Gen 7) with speeds up to 854 MHz. Regarding I/O and expansion, there is one mini PCIe M-SATA slot, as well as a single SATA port and a 4-pin EPS 12V for power. Other connectivity includes two Realtek RTL8111E Gigabit LAN ports, HDMI output, and two USB2.0 ports.

    I get that the PCIe slots are in the 16x form factor, but they aren't actually running at 16x data rates, are they?
  • jagilbertvt - Friday, November 10, 2017 - link

    The j1900 only has 4x PCIe 2.0 lanes, so even if they are x8/x16, they must be using a PCIe switch for connectivity between the CPU and GPUs.

    You don't need them to run at 16x. It's ok with a PCIe switch. I got into this whole mining craze but I have a feeling I'm burning more money on electricity than I'm getting back. And with that whole initial investment... Woo wee...
  • keebs63 - Friday, November 10, 2017 - link

    No, but they don't need to be. Mining takes very little data bandwidth, a 2.0 x1 data rate is more than enough as far as I'm aware.
  • stuffwhy - Friday, November 10, 2017 - link

    They are most likely 1x slots, electrically.
  • Elstar - Friday, November 10, 2017 - link

    Yup. All of these ASIC-resistant/memory-hard alt-coins are friendly to PCIe x1 GPU mining configurations.
  • Mo3tasm - Friday, November 10, 2017 - link

    So, what theoretical hash rate can this thing achieve?
  • jordanclock - Friday, November 10, 2017 - link

    Whatever the best GPU can do times eight.
  • MonkeyPaw - Friday, November 10, 2017 - link

    Don't forget about all that power in the 10W BayTrail Celeron! :D
  • Ro_Ja - Saturday, November 11, 2017 - link

    Nah this is strictly GPU's task.
