    RAM upgrade for Macbook Pro
    My system is getting bogged down despite not actually having many things running. So I have decided to upgrade from 4GB (2 x 2GB) to 8GB (2 x 4GB) of RAM.

    Here are the specs of my machine:

    MacBook Pro (15-inch, Mid 2009) and (15-inch, 2.53*GHz, Mid 2009) - Technical Specifications

    What I would like help with is finding a place to purchase the new RAM. My instinct is to go to or something like that but I have read it is easy to get the wrong RAM for MBP. If anyone knows exactly which type I need and any recommended brand or site to purchase it, then I'd appreciate it. I feel confident I can install it myself, but I want to make sure I purchase the right stuff. Thanks for the help!

    Your machine memory specs:

    Maximum Memory 8.0 GB
    Memory Slots 2 - 204-pin PC3-8500 (1066 MHz) DDR3 SO-DIMM

    Buy your memory from either or Other World Computing. Those are the two suppliers we recommend.
