Ive always had trouble ocin my card, its pretty much never stable above stock speeds (470/1300). I don't really want to do a volt mod because I'm lazy and I don't need to. I had my card at 530/750 and it was okay for awhile but while gaming, the screen would freeze and it would go back to normal with a little choppiness. But when I run 3dmark05/06, I dont have these kind of problems. I just need some advice on what to do.
