Overclocking a G4 iMac

ethernetworks.de has posted a step-by-step tutorial on how to overclock a 166MHz bus G4 iMac.

THey succeeded in overclocking a 15" 1GHz iMac to 1.25GHz, while a 1.25GHz 17" iMac refused to be overclocked*.
If you try this too, please let us know.

* [trans.: maybe Apple's 17" 1.25GHz iMac is in reality a 1GHz machine that's overclocked ;-)]
