Hi all,

I am looking for a processor upgrade for my G3 266 DT, but I'm not exactly sure what ZIF's will be compatable. Are the B&W processors compatible, or just those apecifically designed for the beige? Thanks in advance!

If your Beige G3 uses a "Royal Tech" VRM (voltage regulator module) module located on your logic board, then you cannot run any speed G4 upgrade - from any manufacturer - unless you replace it. Apple used this VRM on only a small percentage of Beige G3 Models. The word Royal is printed on the module for easy identification and if you have put a G4 into a machine with the Royal VRM, the likely result is the burn out of the G4 as well as the logic board.
You may also need to adjust some jumper settings and install cache recognition software.
