There is a clock chip on the logic board which drives the CPU. It is a 33.33 mhz chip on the Duo; I replaced mine with a 37.5 mhz chip, bumping it up to 112.5 mhz. Not a big difference, but with SpeedDoubler and the clock chip mod, it did feel quite a bit faster! BTW, the clock chip change had nothing to do with the logic bd. failure. That was a bad display or backlight supply board failure. Cheers! Andrew ---------- Duo/2400 List, The friendliest place on the Net! A listserv for users and fans of Mac subportables.
