SLI 670 not working

post #1 of 7
Thread Starter 
My problem is that when I enable sli I get massive screen flashing in fullscreen games and very poor performance in windowed application, 60 fps is valley benchmark. When I play with the sli bridge with AoM running the screen flashing changes in length

Things I have tried
New Sli bridge from by brothers motherboard
Reinstalling drives
switch locations on the motherboard,
changing the bios to be gen 2 and gen 2

IS there anything else I can do or should I sell the graphics cards?

What motherboard, psu, and graphics cards do you have? This is essential to solving the problem.

Perhaps you have to enable x8/x8 speeds within the BIOS?

Does each card work alone in each slot?

They were at the same clock but it didn't help, now they are on default profiles.

Each card works in both slots, i have set it to x8 x8 in the bios.
