Victor, I'm going to assume that you have the same ECS K7S5A mobo you mentioned in the other thread. If your system won't start into BIOS where you can change the bus speeds, you should clear CMOS. See section 12 of this guide:
Also, if you're going to be overclocking your system, you should read all about the motherboard at that site and find a forum where other overclockers hang out. HowToGeek is not a good place to learn from other overclockers.
