You'll see that most cards out there will all tweak to roughly the same levels due to all kinds of hardware protection kicking in. We've prepped an updated build of Afterburner for you ( version 4.6.0 download) that you can use to tweak the card both manually and with the new curve based OC scanner (next page). I really wouldn't know why you need to overclock today's tested card anyway, but we'll still show it. Carefully find that limit and then back down at least 25 MHz from the moment you notice an artifact. Usually, when you are overclocking too hard, it'll start to show artifacts, empty polygons or it will even freeze. Usually, when your 3D graphics start to show artifacts such as white dots ("snow"), you should back down 25 MHz and leave it at that. More advanced users push the frequency often way higher. Example: If your card runs at 1500 MHz (which is pretty common these days) then I suggest that you don't increase the frequency any higher than 25 to 50 MHz. I always tend to recommend to novice users and beginners, to not increase the frequency any higher than 5% on the core and memory clock. It sounds hard, but it can really be done in less than a few minutes. By increasing the frequency of the video card's memory and GPU, we can make the video card increase its calculation clock cycles per second. Typically you can tweak the core clock frequencies and voltages. As most of you know, with most video cards you can apply a simple series of tricks to boost the overall performance a little.
