    I'm planning to upgrade my RAM soon and was wondering if anyone knows if there run at full speed or just get underclocked to 1066.

    Thanks

    Im pretty sure it will run at the slower speed - for example, I put 133Mhz in a G3 iMac - It only runs at 100Mhz. This is due to the limitations of the logic board.

    The FSB is set to 1066, so faster RAM will just run at the FSB's speed (unless you overclock to a higher bus speed somehow).
