    Alright, I just upgraded to a new base model MBP- coming from a G4 PB. I ordered 2 x 2 GB Crucial RAM from Newegg to boost my memory.

    Now, when I install both 2 GB sticks the MBP doesn't boot, just a black screen and some fan activity. I've tried installing each of the 2 GB Crucial sticks separately- same result, black screen, no boot up. Only when I use either 2 GB Crucial stick with one of the 1 GB stock RAM sticks does the MBP boot and then recognizes 3 GB RAM.

    The Crucial sticks aren't at fault I guess as both work in conjunction with a 1 GB built-in RAM stick. I would rather not want to exchange my MBP as it is flawless in terms of absence of yellow tinting, no screen gap, etc.

    I've upgraded RAM for various Mac machines a number of times and never had any problems. This one puzzles me. Any help/info is much appreciated. Thanks in advance!

    that is a weird problem indeed, when you put one crucial 2gb RAM with the original one, does it boot no matter if the crucial is on the top or bottom slot? just curious. if you don't get it sorted you should just get 2 new RAM sticks, they probably have lifetime warranty.
