Intergrated Graphics overclocking

I have a Acer Aspire 3000 laptop i got not too long ago for christmas and the intergrated video is 64mb with a core clock of 166MHZ and a mem clock of 350MHZ. The low core clock is creating some low FPS and is really starting to tick me off and I cant upgrade this sucker because it's intergrated BS. Can someone help me overclock this properly? The intergration chipset is a SiS760 Mirage 2.

AMD Mobile Sempron 3000+ 1800MHZ
512mb Ram

I wouldn't overclock, much less a laptop

Overclocking laptops is like asking for molten plastic.
