Overclocking Alu PowerBooks...
MacXTREM has managed to do just that
. Their 1.5 GHz 15" PowerBook now is running at 1.83 GHz. Several configurations are theoretically possible, but as always with such things, you probably just shouldn't
do it unless you know what you're doing. If you don't, you should rather sell your PowerBook now (and I mean NOW!) before Steve announces the new ones, which you can then buy. ;) Should be easier than overclocking. And safer, too.
