    I've read that my MPB (early '08 2.4 GHz 15 inch, pre-unibody) can actually support up to 6 GB of RAM despite Apple's specs of 4 GB max. I currently have two 2 GB 667 MHz DD2 SDRAM (Kingston) in my machine. I was thinking of switching one of those out for a 4 GB chip. My question is, would it be wise to use a different brand chip for the 4 GB (say, Crucial?) or is mixing types a bad idea? Also, does speed make a difference? Would a 800 MHz chip cause me problems paired with a 667 MHz 2 GB chip?

    I appreciate any advice you guys have. I've done my homework on RAM but the details still confuse me...

    Brand shouldn't really matter, but definitely get the same speed. Different speeds can cause issues.
