I have a MBP with a 2.16GHz Intel Core 2 Duo processor. I am planning on upgrading the RAM soon. It says that it can upgrade to up to 3GB. But I went on OWC's website and I noticed that on their benchmark testing page that they have a MBP 2.16GHz Core 2 duo running 4GB. Is it possible to upgrade to 4GB instead of up to 3GB? here is the link: http://eshop.macsales.com/shop/apple/mem... my macbook pro is the blue configuration. what is your opinion? should i upgrade to 4GB? or stick to the recommended 3GB? is anybody out there running a 2.16GHz core 2 duo MBP with 4GB of RAM???
