Upgrading rig from 3 to 5 GPU cant get 5th card running...

[systic]

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...

I have heard windows 8 works better with more than 4 cards. Worth a shot.

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
