Hi, I have a 13" MBP. It is more or less three years since I have had my MBP. I am going to start doing video and I would like to add RAM to it. My MBP has an Intel Core i5 processor and its speed is 2.3 GHz. It came with a(n) standard 4 GB of RAM and I think one can max out to 16 GB. Should I max out to 16 GB? Are there any 'Side effects' when maxing out RAM to 16 GB? Should I keep it at 8, 10, or 12 GB? Last, but not least, where do you suggest to get RAM from? Thank you in advance, kind regards, igmolinav : ) !!!
