Overclocking with my mobo

[Excaliber2k]

Im trying to overclock my duron 750 i just got a new h/f and some arctic silver thermal paste and am prepared for cooling but my mobo doesnt want to let me. My bios wont let me change my voltage and my mobo has no jumpers to change cpu speed or has any multipliers. Its a SiS something with onboard video/audio/ethernet i wanna know is it still possible to overclock, im fairly new to hardcore o/cing and wouldnt know what to do now.

I'm guessing that you're going to have to go with something like SoftFSB to overclock at all. If you check the Utilities link on the side bar on the front page, there's a link for it there (I think) or you could do a google search for it.
