1) Wrong section - this is for Bitcoin, you need to ask this question in the alt-coin area.
2) Apparently Winblows 10 has problems running more than 4 GPU cards...

I had the same problem and I seen your thread.
I figured out the problem and I though I should share it.
You need to go into your BIOS. Go into Advanced settings.
Then go into Advanced System Agent Configuration.
Set Above 4G decoding to ENABLED.
And poof it will work. You need to do this on any kaby lake board I believe.
