    I have the base 13" MBP with 2gb of RAM and was thinking of upgrading to 4gb. My girlfriend has an old Powerbook G4 1.5GHz with only 768mb of ram and I am wondering, will my old ram will fit in her powerbook? Thanks

    No, her Powerbook uses DDR RAM and your Macbook Pro uses DDR3 RAM, and other different things like pins etc.

    The new MBPs use DDR3 RAM, the PowerBook G4 (from what I can tell) used DDR RAM, so as far as I know, the answer is no.

    Damn I was beaten. Too slow.

    You sure the pins are different? I thought that the faster ram would just run at the slower speed of the powerbook, is that wrong?

    Yes that is wrong. If the two computers were running the same type of RAM (DDR, DDR3 etc), you could mix different speed sticks of RAM and the faster one would slow down to the same speed as the slowest one. But mixing different types of RAM (one stick of DDR, one of DDR3) or putting the wrong RAM in a computer (DDR3 in a DDR-compatible computer) does not work this way.

    If I remember correctly, DDR3 has 204 pins, while ddr has 200.
