I have a Z77A-GD55 and I can't figure out how to get 4 7970s to work on it. I was able to get 3 working without any problems. Does anyone else have this board?

I am downloading windows 8 right now and will try that, but after reading through this thread, It seems like I shouldn't need to switch from 7 to 8 with only 4 cards.

I have this board (Z77A-GD55) and am currently running (5) 7950s on it, no presence shorts, dummy plugs, or powered risers. I just run the cards at stock clocks (925/1250) and under-volt them to prevent the need for powered risers. My current setup is Win 7 Ultimate SP1, 12.6 drivers and cgminer 3.1.0.

I get about 565Kh/s with this config: -w 256 -I 19 -g 1 --thread-concurrency 16384

My plan now is to see if I can get 6 cards working on this board.

Had to presence short the 6th card for windows to see it, but it's showing up as error code 43 in device manager.

From reading back through this thread, it seems that no one has been able to get (6) 79xx series cards working with Windows 7 or am I missing something? Everyone running 6 or more of these cards from one board is using Windows 8 or Linux correct?
