Not all Macs can be over clocked, but three models in the Mac II lines can – the IIsi, Iivx, and “wicked fast” IIfx. These pages provide information on the maximum reliable speed, which may vary from one machine to the next.

ATIccelerator II can change ATI graphics cards frequencies live, on-the-fly, under Mac OS X. It's much more sophisticated and convenient to use than Graphiccelerator for the following reasons:. no potentially dangerous flashing required.

- Oct 30, 2013 There is so much wrong with this post, and not because it's a Mac. Overclocking and laptops are two things that need to stay far away from each other. Overclocking increases heat output, and laptops are hot enough already. Having an overclocked laptop play a game for 1 hour+ is a bad idea, and will greatly decrease the lifespan of at.

There are also third-party upgrades for most Mac II models, including some 68040- and PowerPC-based ones that should provide a much bigger boost, albeit at a higher price and likely difficult to find nowadays.
Mac IIsi
The Mac IIsi comes with an 40 MHz oscillator, which runs the computer at 20 MHz (half the speed of the oscillator). You can put in a 50 MHz oscillator to run the computer at 25 MHz quite easily. You may be able to put up 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 user 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 system clock runs faster and the pitch of the sound is higher. Also, you will need a heat sink for the 68030 when running it this fast.

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 of these chips and is now running the computer at 60 MHz without problems. The Processor Direct Slot (PDS) will no longer work in an accelerated IIfx.

When the user wants to exceed the limits of the graphic card, they make use of GPU overclocking software. This is not at all scary and is pretty easy as well as precise and you can access the video card settings using this. When the GPU clock frequency, as well as voltage and fan speed, is increased the performance as well as the temperature can be balanced and the graphics card potential can be increased. There are different kinds of CPU overclocking software download which are available and also intel overclocking software for various intel processors.
