I have a few questions for minds greater than my own. I want to increase the amount of RAM in my iMac G4 (1.25 GHz, 167 MHz bus) by 1 GB, but I don't know if it is possible. My questions are these: 1) Can a G4 iMac handle a 1 GB stick of RAM? 2) Can a computer with a 167 MHz bus use 333 MHz RAM at a slower speed? 3) Is there a limit to the amount of RAM an iMac can use (ie is there a point over which more RAM will have no effect)? Thanks.
