Hey folks.
I recently acquired a beige G3 Server 300 mHz. While opening it up to remove the battery and clean it up I noticed the processor is in a zif socket and it was they same processor type as a G4 450mHz I had lying around. I popped the 450 into the socket and it booted up but when I went to Apple System Profiler it said it was a G4 300mHz. Is there something I need to do to unlock the extra speed or do these machines max out at 300mHz? Thanks.
