XLR8YourMac.com is running a story that reveals that the new iBooks, based on the PowerPC 750FX CPU (the IBM "Sahara"), can be overclocked in software. Whereas the bus speed/multiplier of previous G3's was set by resistors, this new G3 allows configuration via a CPU register. A user installed Apple's CHUD tools on his iBook 700 and was able to get it running at 800MHz. There seems a possibility, with more documentation, that even higher clockspeeds could be obtained. Great news for all daring owners of the new iBooks.
