Overclocking can get hugely complicated, often depending on what features are included in the motherboard's BIOS, and if the CPU is unlocked or not. A constant is that overclockers hope to get more performance out of the CPU they're using, and since the factory settings are optimized for the least problems from the manufacturer's viewpoint, you can usually have at least a little success -- every CPU & system is different, so the settings have to be individualized, with some having much greater success than others.
AMD & Intel hope to make it a little easier for more casual users to take advantage of overclocking, and each have released software utilities to make it as easy as clicking some boxes / links in their apps.
