Take the subject name you cre

Take the subject name you created, "Overclocking a powerbook G3" and paste it into Google.

The first link that comes up tells you just how to do as you asked:

Bekkoame's site is cool. I've used it many times. Since you have a 266Mhz machine may I suggest using pbg3e1.html

http://www.bekkoame.ne.jp/~t-imai/pbg3e1.html

I think you'd be safe going to 300Mhz from 266. I prefer to not fuss with the BUS PLL's much. It would require you to adjust the clock speed jumpers again but your milage may vary. For instance, at 300Mhz and a 66Mhz bus you'd use the 4.5 multiplier. But at an 83Mhz bus the CPU would be at 373Mhz and would probably crash left and right if it booted at all. Just changing your BUS to 83Mhz would give you 333Mhz but again it might crash alot. Furthermore using the 83Mhz BUS you'd have to use a multiplier of x3.5, but that'll only give you 290Mhz. So that's how that works, eazy eh? =)

Let us know how it works!

Technically it's going 266.666666 MHz, but it rounds up.
