The PNY Geforce 3 Ti 200 comes with the powerstip utility to overclock this video card, however I decided to use coolbits which is a simple registry entry that will allow you to change the core and memory speeds with almost any nVIDIA video card.
As you can see from the images above I was able to overclock the core clock frequency from the stock 175Mhz to 200Mhz. I was also able to overclock the memory clock frequency from 400 to 460. I tried to get the memory higher but when I changed it to 480 I started getting artifacts, so I moved it back down to 460. This card is a great overclocker, as you can see I gained 25Mhz on the core, and 60Mhz on the memory. With this overclock I am at the stock speed of a normal Geforce 3. I redid each benchmark with the overclocked speed at 1024×768 for a bit of comparison.
With the overclock 3DMark 2000 increased its score by almost 1000.
3DMark 2001 increased by a little over 500 points.
Vulpine GLmarks FPS at 1024×768 increased by about 8.
Quake III increased by 13 FPS in Demo001.
Serious Sam increased by just over 8 FPS, similar to GLmark.
