I have a asus p6t regular with sli and crossfire 17 920 overclocked to 4.0 and I can't get sli to work between the 460 and 460 v2 It doesn't recognize both as sli but it does desperate I tried the sli hack that allows you to use 2 different gpu's it accepted it as sli but when I play a game or restart the screen goes black and stays black
