I've run into an issue, in my 7x GPU rig (yes, for mining), where the 7th card connected to my motherboard (Z87-G45) cannot be used due to "code 12: not enough free resources." If I can somehow run this GPU off of USB or another non-PCI-e interface, this should solve this problem.

I use USB to PCI-e risers, like this: https://bitcointalksearch.org/topic/wts-usb-style-pci-e-1x-16x-powered-riser-cables-595-ea-25k-sold-392536

It connects to the GPU via PCI-e, but theoretically I could plug the other end directly into a USB port, while giving the card power as usual via SATA. Could this work, and would the PC recognize it? Thought I'd ask before I tried and fried something.

Thanks

Don't do it. While a USB cable is used, the signals sent through the cable are not compatible. At best it wouldn't work, at worst you fry something.

I have same problem, just tried to get the 7th card running, still without success. Using also the MSi-Z87-G45 board. Will post here if I find a solution on the way to RiCHDoM
