Okay, so I have two 8800GTS 640MB cards and whenever I enable SLi in the nvidia control panel I get colour distortion and flickering when they start rendering in 3D.

I am running Windows 7 x64 that I upgraded from Windows Vista x64. The SLi bridge is fine as are the individual cards. I've tried both the latest WHQL driver and the beta driver.

Something else to note: I am unable to change the clockspeeds of my GPUs. The option isn't present in the nvidia control panel and there are no advanced options in RivaTuner.

Edit: Also, my PSU should be more than enough, it is 750 watts.
