Nintendo Wii Overclocking?

[Asdfguy86]

Does anyone know how you would be able to overclock a Nintendo Wii? Is there special software, a specific FSB jumper or something like that? The Wii runs version 4.3U, and is softmodded. The reason I want to do this is to make things load a bit faster and for games to run faster on it (An MS-DOS game, Doom, hardly gets 7 frames). Any help is appreciated.
