I have a G4 Power PC and I am wondering if you can over clock it and how safe is it?
That depends. If you are thinking of adjusting voltage and clock timings in 'BIOS' the answer is no. Certain models used resisters on the logic board to set CPU speed, bus speed, etc… But those are older models and it's not as easy as overclocking in the Windows world.
And then there were some CPU upgrades available for some Mac models that would increase the CPU clock speed, but you were still stuck with a fairly slow bus speed.
There have been some successful board transplants, such as a 1.25 GHz board into a 1 GHz Power Mac, or a 1.25 GHz board into a 700/800 MHz iMac.
Your options depend entirely on what MODEL of Mac you have and WHICH G4 Power PC is in it. The list can be of more help if you are more specific in your request.
