A friend of mine has a MDD dual G4 at 867 Mhz with what I believe is a 133 Mhz bus, and he needs to replace the processors on the system. I have a 1.25 Ghz G4 from a MDD, but I think it's a 167 Mhz bus. Would I be able to put it in my friends computer? Would he need to tweak it to make it work if it did work, or would it work normally without any soldering?
