I've been mining for a few months now.
And have a steady hash rate with 3 Zotac GTX 1070 cards (90 MH/s)
I've bought an extra card (MSI GTX 1060) try to install it, but when installed the mobo won't boot and gives me a hardware error even before i get the bios screen.
I've try'ed with only the GTX 1060 card and this works fine without the 1070 card installed
But the combination of both card will end up in not booting at all.
Can someone please help with this.
