Colorful Intros Unique C.J1900A-BTC PLUS V20 Mining Motherboard
Colorful today introduced the uniquely designed C.J1900A-BTC PLUS V20 motherboard for mining rigs. This odd-ball form-factor board is designed for makeshift racks, and removes the need for PCIe riser cables. The board itself is a large PCB with nine PCI-Express x16 slots with 1-slot spacing, of which eight can be used for installing your mining graphics cards (x1 wiring), while the slot on the middle (blue), isn't really a PCI-Express slot.
The blue slot has custom wiring for the business end of the motherboard, a riser card which houses the Celeron J1900 SoC, a DDR4 SO-DIMM slot, an mSATA 6 Gb/s slot for your SSD, and the board's main connectivity, which includes two USB 2.0 ports, two gigabit Ethernet interfaces, and an HDMI display output. If you have trouble finding an mSATA SSD in 2017, there's also a standard SATA 6 Gb/s port. The riser draws power from a 4-pin ATX input. The main PCB has eight 6-pin PCIe power inputs, which wire out to 6-pin PCIe outputs near each black slot. This is more of a cable-management feature, smaller (20 cm long) male-to-male 6-pin PCIe cables connect the outputs to the graphics cards.

Ans. Yes.

If my memory serves me right, J1900 and that whole series is limited to x4 PCIe 2.0 lanes total.
EDIT: oh,wait... I see. It's most likely ASM1184e or ASM1187e
EDIT: From the specs page... DDR3L SO DIMM

To Colorful: You are so close to a sub ITX motherboard! Male one with a few ethernet ports and some USB and SATA and an M2 and we'll all be happy.
I've seen lots of local miners also using embedded Carrizo boards or cheap AM1 rigs w/ passive cooling.
Overall it translates to 400-500kWh/year, which isn't much, but still saves almost $50 on operational expenses in my country, and definitely much more in EU or US. It supports both DDR3 and DDR3L. It's not bad by any means. Actually, quad-core BayTrail is slightly faster than Braswell (2015-2016) in most tasks, while only has a slightly higher TDP and lacks certain multimedia features (HEVC acceleration, 4K60Hz support etc.).
I'm currently building a mITX rig for my office based on Pentium J2900, cause my electricity is almost twice as expensive, as in my house.
P.S. It is also worth noting that both NICs are Realtek RTL8111E.
Just correcting the OP as it says ddr4 in the first post... and single slot spacing...its double.
Its still like nobody is editing these before they go live.... :(
