    I just upgraded from 1 gig of RAM to 2 (crucial/samsung). Now, every time I try to turn on the MBP (2.16 core duo) the screen stays black and nothing happens for about 20 seconds and then makes the start up noise and boots up.

    Its not TOO much of an inconvenience, but I was just wondering why this is.. thanks

    You might want to start with removing one RAM module and booting up on 1GB instead of the 2 and see if the problem persists. Then try and switch the chips in their slots, ie put RAM module 1 in the lower slot and RAM module 2 in the upper slot. Let us know what happens.

    Memory check?

    I took my MBP from 2 to 4GB, and noticed the same thing. My guess is that doubling the RAM doubles the time it takes to test the memory at boot time.

    Only thing i could think of regarding that is that there is more memory for it to check while it is booting up. So yeah, what you are saying is all i could think of, unless something is wrong.
