Horizontal Flicker when over clocked

post #1 of 5
Thread Starter 
Ive got the ATi 5750, running on 3 20" monitors, when i ran the auto tune for overclocking it sets it at max. in game performance is great, but when loading the game or ie scrolling i get a horizontal flicker. disable or lower clock speeds and i get a video lag in game. I have latest drivers and even tried the MSI afterburner software and still same issue.

any help would be great

That is a known ATI bug for multiple monitors.

The problem is caused by the memory speed chaning between different powerplay states.

I solved mine by flashing my bios with the same memory speed across all powerplay states. Other people reported fixing it with MSI Afterburner profiles.

I personally prefer the first option and I have not had any problems with it. It fixed the issue with my old HD4850 and now with my HD5770.

The states change whether you are idling on the desktop, or playing a youtube video (flash), or doing some 3D design, or gaming. The way you know is from the GPU/MEM clocks.

Are you familiar with flashing a GPU's BIOS? Ever done it before?
