I have a 5.1 MacBook Pro (5.1 Model Late 2008) with 4GB of Ram. All the apple documentation I can find that the maximum supported for this model is 8GB of RAM (2 x 4GB). Has anyone tried to put bigger DIMMs into one to see if they would work? Given the price of RAM at the moment I would go for 2 x 8GB if I knew it would work.

I'm seriously wondering why you need so much RAM? Most programs don't even use/support that amout of RAM. –  Michiel Dec 21 '11 at 8:18
    
@Michiel - you obviously don't use a lot of VMs/heavily multitask. I have 8 GB in my MBP, and regularly get down to ~400 MB free. –  Fake Name Dec 21 '11 at 8:58
    
Ok, I stand corrected. Didn't now you were using VMs :) It's worth the investment in this case :) –  Michiel Dec 21 '11 at 9:10
    
@Michiel: I'm a developer running with a Linux VM and several database platforms. 4GB is entry level to me. –  My Other Me Dec 21 '11 at 9:39
    
@MyOtherMe, forget what I said. You need as much RAM as you can get! –  Michiel Dec 21 '11 at 9:49

Your Macbook Pro supports only 8GB (15'') or 6GB (17'') of RAM.

Apple states that it's 4GB, but OWC continuously check the max. supported RAM.

See this list here.

For anyone interested I went with 8GB or regular Kingston Ram running at 1333. Worked fine despite the original spec saying it needs 1066 –  My Other Me May 23 '12 at 9:44

I have mine in the exact some setup... be sure you zap the PRAM after you install them. –  unmircea Dec 12 '12 at 21:06
