Overclocking the Mac mini
Yes, it’s been done.
This guy took his 1.25GHz mini and overclocked it to 1.42GHz. Via four jumpers, the G4’s speed can be selected between four settings: 1.25, 1.42, 1.50 and 1.58GHz. He tried 1.5GHz, but had stability issues.
I probably won’t be this bold, as the jumpers are really, really tiny and I wonder if I could even get 1.58GHz out of my faster G4 (it wouldn’t be worth it for just 1.5GHz). Maybe when the warranty runs out and I dramatically improve my SMT soldering skills…
