With my upcoming B&W upgrade project, I'm going to find myself with a spare 450mhz ZIF G3 CPU that I'd really like to install in one of my beige G3 desktops(the one I'm intending to take in and use at work). I've been told that this upgrade should work. With that said, as per the service manual the processor clock speed needs to be set on the logic board. The service manual seems to indicate that the computer won't even boot if the jumpers are set incorrectly. The problem is that the jumper settings in the service manual max out at 300mhz(see attachment below). Is there a combination of jumper settings that will allow these computers to run with a 450mhz processor?
