I've found a way of changing the bus speed on my G4, but what I want to know before I go ahead and solder things, is will it actually make a difference? Currently its running at 1.0ghz (Dual) from 867mhz, and putting the bus speed up to 167mhz will put it way over that, but, setting the multiplier back to default and putting the bus speed to 167mhz will give me 1.0ghz again. Your thoughts?
