Hi folks,

I got this card today and have experienced a problem with it, after I installed the card and installed the 12.7 beta drivers and it works perfectly fine in windows, but when I try anything extensive like a newish game like Witcher 2, Secret World, SWTOR the games work fine for 5-10 seconds and then all of a sudden they start to stutter and the sounds gets all distorted, although I ran Men of War Assault Squad and it ran perfect.

Also on desktop when I open some windows there is a strange flicker at the bottom of the screen, i have 2 videos here to demonstrate the problem.

Please watch the 720p versions as you can see the problems better.



My specs are

I7 3770k
Asus P8Z77-V Pro
16GB DDR3 2133MHz
128 Hitachi SSD 830
500GB HDD
150GB HDD
OCZ 550W 80 Bronze PSU
I use the onboard sound from GPU

What I have tried is a fresh install 12.7 beta and 12.6 drivers but the problem still remains, removed everything except SSD and run bare minimum, problem is still there.

Any suggestions would be most appreciated?

Go further back on drivers. Some people report 12.4 seem to be the best.

I will try this.

Are the clocks at maximum while this is happening? The in game stuttering?

The clocks are at the factory setting I ran GPU-Z and it said 1070mhz all the factory settings, all temps and fan speed was ok, I just tried a new HDMI cable and the other DVI port also a new DVI adaptor and then ran SWTOR but it does the same thing, game works perfect for 5-20 seconds then sound crackles and distorts then the game start to stutter the more you continue the worse the stutter becomes.

I tried 12.4 same thing, I put the card in the other PCI express slot and same thing, I am out of options any ideas?, I tried Witcher 2 again and on the loading screen I got aload of flickering lines, and in game worked fine for 40 seconds and then same problem :(. the sound is like radio static.
