It came to my attention that there in fact IS 4GB sticks of DDR2 memory around. http://www.newegg.com/Product/Product.aspx?Item=N82E16820231210 I have a Early 2008 Penryn 17" Macbook Pro. I'm currently Running Snow Leopard at the moment. I did some searching on the forums and couldn't find a definitive answer. Is it possible to install 8GB of ram on my MBP? Or is it too old? I was curious if this might help encoding performance in Final Cut Pro at all or anything else.
