Upgraded from a 4870 1gb to a 4870x2. Installed all new drivers and everything but when I go to play a game or run 3DMark it goes into a blank screen and has to be reset. Anything would be helpful guys.
Running Win 7 64 bit and driver versions 10.2

well my friend has one and its running fine with the newest drivers, maybe clocks problem ?

all clocks are at default. I havent touched them at all

redo windows on a spare drive just to see if it helps.

Thats the only other thing I can think of to do. I have even tried older drivers and everything. Lame!
