Fajar,
You can diregard DarkMajiq's suggestion. (Not that it's wrong. It is correct. Just doesn't apply to you).
What you will need to do is either modify your board in accordance to said diagrams, or you can try to manually modify the bridges on the CPU so that you can get the desired speed. This would involve cutting and connecting the bridges on top of the CPU, and consequently would make it a timeconsuming process to determine your CPU's sweet spot. It would be a good idea to find someone with an overclocking board so that you can more easily determine what settings you should use. After this is done, then you can cut and connect once and be done with the thing. Either way, its no easy task. Good luck.
