    Hi,

    I got a question. I had a bad motherboard in my Powermac G4 MDD Dual 1.42Ghz. When I replaced the board with another I got my 1.42 now shows up as dual 1.13Ghz and the 167Mhz speed dropped to 133Mhz. Would the processor speed drop down like that if this board is a 133 instead of the 167?? I was told it was 167Mhz with the firewire 800 port, which it has. Is there a way to tell what speed the board is??

    Thanks,
    Koozman

    As a rough guide you coud try running Xbench and then comairing your results to mine as I have the dual 1.42. This is not very scientific but is a good illustration of if is far off mine...

    The bus speed is selected is selected by the placement of certain resistors on the motherboard. Google for overclocking MDD or similar.
