    Hey guys,

    Just a quick question here,
    I'm wondering if my MBP will support an 8GB RAM upgrade!

    MBP specs: 13", 2.26Ghz, 2 x 1GB RAM, 160HD, Mac Os Lion, Mid 2009.

    I upgraded my RAM to 5GB recently, 1GB + 4GB and it's working fine. I bought another 4GB module and installed it but I get a beep sound when I turn MBP on!

    I read on the Apple support page that my MBP should support 8GB ram.

    Any ideas?

    Thnx!

    The 2009 MBP model supports 8 GB of RAM, it just might be, that the new 4 GB module is faulty. Return it and get a new one.

    ^ That and I would also make sure the sticks are the exact same model. When running in dual channel mode you don't want mis-matched pairs.

    I removed the "old" 4GB module and installed the "new" one. It seems to work fine with the 1GB module which indicates that the "new" 4GB module isn't faulty. I installed the 2 4GB module but they don't seem to work with each other! I still get the 3 beep sound/long pause/3 beep sound

    Can't remember where i found this:


    1 beep = no RAM installed
    2 beeps = incompatible RAM types
    3 beeps = no good banks
    4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
    5 beeps = processor is not usable


    Thnx for the quick reply!

    I'm afraid not. The closest i could get to ram upgrade was 6GB.
    I would suggest you to contact any local Apple Store and ask them. The best would be to go there directly, ask them to upgrade the ram on your MBP and see whether it's possible or not.
    Unfortunately I don't have any Apple Store where i live.

    I had 2 x 4GB sticks of RAM installed in my 2009 MBP and it worked just fine. Was it a matched pair of RAM?

    Yes. I tried several times with different pairs of sticks. Same result every time..thus the suggestion to consult an Apple Genius.

    Noob here. Sorry.

    But I'm looking to upgrade to 8gb RAM on my MBP mid 2009.

    My question is, how do I make sure the RAM I buy is compatible with my MBP?

    Hey JoeMahmuh, you can use this Crucial site to find the compatible RAM upgrades for your MBP. There are other brands as well that make compatible RAM.
    http://www.crucial.com/usa/en/apple-memory

    I plugged in your computer model and it says
    DDR3 PC3-8500 • CL=7 • Unbuffered • NON-ECC • DDR3-1066 • 1.35V

    So if the RAM follows those specifications, it should work fine.

    Hold off and get a broadwell or bin it now and get a retina.
