    I want to do this to increase the speed of my sawtooth. I think that the dual 500mhz was the last apple processor that is compatible with the sawtooth because they both run on 100mhz busses, correct?

    If you mean genuine Apple module with plug&play installation, the answer is yes.
    Check first is your Sawtooth is DP capable (some wasn't). Use this utility: http://www.macupdate.com/info.php/id/13551/uninorthasicchecker

    With a little tweaking (soldering will be needed), you can fit there CPU daughtercard from DA (less tweaks needed) or Quicksilver (more tweaks needed). It's also possible to overclock system bus to 120 MHz.

    Third way is to find for cheap third party CPU upgrade. Some of them, like Sonnets are auto adjusting to system bus speed - would work with Sawtooth with 100 MHz bus or DA, QS with 133 MHz bus.

    Yes I was talking about apple genuine parts. The reason I would get one of those instead of a sonnet is because I could get one for a good price.

    Does this mod needs any messing with resistors or something to change the "multipliers" to give 500MHz?

    Since those are on the CPU AFAIK, you shouldnt have too as the new CPU unit would come configured as a 500Mhz Dual.
