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 have upgraded the RAM to 8GB for my MBP470. See the config below. No problem happened. Be noticed that, 470 only support 1066MHz DDR3 RAM. Do not use 1333MHz RAM. The 8GB RAM is from Sumsung.
It is certainly possible to install 8GB of RAM on this model. You will need to check if you have the correct Boot ROM Version and install it if needed. Follow this guide.

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.
