Overclocking a PowerBook Duo

Apple’s PowerBook Duo notebooks were very lightweight and very portable, but they are very limited in connectivity unless you can acquire a Duo Dock. The Duo 201, 230, and 280c can all be overclocked. If other Duos can be overclocked, we have not found reports.

Many Macs 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. Modifications are done at your own risk.

Be sure to visit The Clock Chipping Home Page, the definitive resource on chipping the Mac.
