    ^ this one

    The newer memory won't work in that model.

    Stick to 667MHz since the Early '08 MBP's memory controller clocks at 667MHz. No reason to use something clocked higher if the controller can't read the higher speeds.

    They physically won't fit and the voltage is wrong... but otherwise ;)

    Yeah, 6GB works on the Early '08 model, but I'm not sure about 8GB. I think the 8GB only works on the new 17-inch MBPs.

    Only 6 GB; if you search, you can even find the whole thread on it. ;)

    Since 6GB means 2GB + 4GB modules, does this mean interleaving/dual channel memory access wont work since the modules aren't matched?

    Yep, exactly, no dual channel, but most say you wont tell the difference. Unless your doing some memory intensive stuff
