BIOSTAR m6tlc won't overclock past 266MHZ

[cyberhopper]

Hi, I'm new here so be gentle.
I have tried changing the jumpers on The motherboard as the manual says but I only get 133Mhz , 200Mhz or 266mhz. Do I need to anything more.Thanks for your help.
cheers

you need to feed us some more info....
what CPU do you even have?
Motherboard name and model.

and you MAY not be able to change the multiplier on that CPU.. as they are often locked, so changeing the BUS speed may be the only way you can overclock your computer
