I was hoping I could get some guidance/assistance on getting my BTC-37 Mining board up and running. I searched (maybe incorrectly) but only found threads about older Onda? D1800 motherboards, and it's 156 pages so I am not done reading lol. Great thread @philipma1957 and all those involved.
I managed to get the motherboard to boot to windows from a cloned SSD, using DDR3 SODIM laptop memory.
BUT when I put one of my 1070's in the PCIE slot (slot marked #1) and provide power (single 8pin), and plug in the HDMI cable in, I get a black screen. Unplug the HDMI and plug it back into the motherboard HDMI and widows comes back up on the monitor.
The BTC 37 motherboard does have QTY (

6pin connectors adjacent to each of the 8 PCIE slots (see 1st image link below). I did provide power to 1 6pin connector, the one labeled the same as the slot for the 1070 (slot #1), still nothing.
Do I need to provide cables/power to all 8 6pin connectors to even run a single 1070? I recall in philipma1957's thread that the Onda D1800 needed power to all 6 Molex connectors. I maybe screwed if I need to power all 8 of my 6pins to run a single 1070, cause I only have a Seasonic Focus 850 PSU.
Or am I missing something else? Did I search incorrectly, and someone explained this already? While I have built custom loop water cooled gaming rigs in the past, the mining setups are totally new to me. I was really hoping I could figure this BTC board out, but I fear I bit off more than I can chew and may have to cut my loses and buy a mainstream motherboard and run the 1070's I have here sitting idle.
Any help would be greatly appreciated, thanks all.
Crap, I can't even figure out how to post pictures from Imgur LOL...
