Chipping the Mac
Chipping the Mac II Series
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.
Mac IIsi
The Mac IIsi comes with an 40 MHz oscillator, which runs the computer at 20 MHz. You can put in a 50 MHz oscillator to run the computer at 25 MHz quite easily. You may also be able to put up to a 55 MHz oscillator in it, to run the card at 27.5 MHz. The limiting factor here is the floppy drive controller. Also, the FPU in the PDS to NuBus adapter and Ethernet cards may not be able to run at these higher speeds.
Mac IIvx
The Mac IIvx comes with a 62.6688 MHz oscillator, which runs the computer at 31.3344 MHz. One person replaced the 31.3344 MHz oscillator (G2) with a 40 MHz oscillator and then replaced the 25.175 MHz oscillator (G1) with the 31.3344 MHz he just replaced. The performance increase was significant, though there were a few problems. The clock runs faster and the pitch of the sound is higher. Also, you will now need a heat sink for the 68030.

Mac IIfx
The Mac IIfx comes with an 80 MHz oscillator, which runs the computer at 40 MHz. Usually, it can be clock chipped to 50 MHz by replacing the oscillator with a 100 MHz one. One person replaced the 40 MHz 68030 and 68882 with the 50 MHz versions, and is now running the computer at 60 MHz without problems.
