    It depends on your specific model MacBook, and the typical caveat is "For best performance, don't mix sizes; always install two identical memory modules."

    There is no harm in attempting it.

    You must remove the firmware password, if one has been set, before you can use AHT.

     

    If you need a new logic board be absolutely certain it is the exact one you require for your exact model MacBook. Buy from a reputable vendor (feedback > 99.5%).

    Can you boot the Mac from your grey Applications Install DVD? It will be the one with "Apple Hardware Test" or "AHT version xxx" printed directly on it. With the disc inserted, restart while holding the c key to boot from the disc, or the d key to run AHT.
