Ill apply the tweak and see if not guess i need to find a vrsion of windows 8 to use
Agreed, Windows 8 will do 5 cards without issue, 6 cards if you do some tweaking
Although you might be able to apply the tweak below to get 5 cards in Win7

I have heard windows 8 works better with more than 4 cards. Worth a shot.
So im running cgminer in win 7 with http://www.newegg.com/Product/Product.aspx?Item=N82E16813128521 It was running 3 7970's just fine and then I added 2 7950's and now I can't get the 5th card to run or be detected in cgminer. I see it in the device manager and tried uninstalling reinstalling but still says a error with code 43. Tried everythign I can think of but no go drawing blanks now. Got 2 psu's with plenthyy of power for everything just not sure what to look at now...
