[QUOTE="shelflife19, post: 691237, member: 41195"] the AGP or "sawtooth" models has a 100mhz bus speed, the quicksilver has a 133mhz bus speed. If it doesn't work it will come up and with errors or dont boot up at all. Im not sure if the 133mhz g4 is backwards compatible. If it is and it still doesn't work try updating the firmware, you will need a os 9.x install in order to update it. Which can be very expensive off of ebay, unless you know someone who knows someone. also make sure you get the install disk not the upgrade disk, it can be very deceiving. One more thing, i dont beleive the QS G4 is going to fit properly, you may have to desolder the pata connector on the edge of the motherboard and be short 2 ide devices. My best guess and it was also my choice when i upgraded my old sawtooth is to buy a upgrade G4 daughter card off of ebay, if you search and search and keep watch you can usually find someone whos selling a upgrade for little to nothing some times. or you can buy a dual 550mhz G4 duaghter card for about 60 bucks off of ebay also, which would be faster than a 733.
