    Hello everyone. I have a macbook pro unibody 13" 2.4 Core 2 Duo. I just installed 2, 4 gb (PC3 8500 DDR3-1066). when i boot the computer it stops half way through the boot up. I thought this laptop could support 8gb. now when i install a 2gb, and a 4gb. it boots up just fine. So if i just use 6gb total the computer boots up fine. Is 6gb the max this computer will support? Thanks!

    Mine is a MBP 13 Mid 2010 Model. C2D 2.4Ghz as well. No problem with 8G of ram so far. =) Hope this helps.

    Interesting. I thought it was the memory, but i installed the same memory on my 15" i5 2.4, and it worked fine on that computer. but when i install it on my 13, it does not completely boot.:(

    If the computer was not made for that memory ie. the limit is 4GB and you go over sometimes it works sometimes it doesnt. some people experienced 1066 RAM computers work with 1333 RAM while others just got kernal panics.

    So its hard to tell exactly why, but going over recommended amounts can give unexpected results. if the computer can use it and its not, than you should go talk to apple, use up that apple care (if still available)

    What generation exactly is your older 13" MBP, though I'm pretty sure they all support 8GB. Bad RAM happens, perhaps one of your sticks is faulty.
