Overclocking & Tweaking

As most of you with most videocards know, you can apply a simple series of tricks to boost the overall performance a little. You can do this at two levels, namely tweaking by enabling registry or BIOS hacks, or very simple, tamper with Image Quality. And then there is overclocking, which will give you the best possible results by far.

What do we need?One of the best tool for overclocking NVIDIA and ATI videocards is our own Rivatuner that you can download here. If you own an ATI or NVIDIA graphics card then the manufacturer actually has very nice built in options for you that can be found in the display driver properties.

Where should we go ?
Overclocking: By increasing the frequency of the videocard's memory and GPU, we can make the videocard increase its calculation clock cycles per second. It sounds hard, but it really can be done in less than a few minutes. I always tend to recommend to novice users and beginners not to increase the frequency any higher then 5% of the core and memory clock. Example: If your card runs at 500 MHz (which is pretty common these days) then I suggest you don't increase the frequency any higher than 25 to 50 MHz.

More advanced users push the frequency often way higher. Usually when your 3D graphics start to show artifacts such as white dots ("snow"), you should back down 10-15 MHz and leave it at that. Usually when you are overclocking too hard, it'll start to show artifacts, empty polygons or it will even freeze. Carefully find that limit and then back down at least 20 MHz from the moment you notice an artifact. Look carefully and observe well. I really wouldn't know why you need to overclock today tested cards anyway, but we'll still show it ;)

All in all... do it at your own risk.

Now I already stated it in the introduction, you pay top dollar or whatever your currency is for this product so NVIDIA made sure you can play around with it overclocking as well.

The 8800 GT at standard at 600 / 1500 / 2000 clocks (core / shaders / memory). But there's definitely room for some more. The card can be pushed towards a core frequency of 700 MHz, the memory at 2000 MHz and the Shaders at 1750 MHz. Yes, we can squeeze even more performance out of your games. No flashy charts sorry, I was out of time.
