Chipping the Mac
Chipping the Quadra
Many Mac models can be "chipped" to run at a higher speed. These pages provide information on the maximum reliable speed. This may vary from one machine to the next. Chipping is not authorized by Apple. Any modifications you perform on your Mac may damage it and will void any warranty. Modifications are done at your own risk.
Be sure to visit Marc Schrier's Clock Chipping Home Page, the definitive resource on chipping the Mac.
