Hey Guys, I have the early 2006 Macbook Pro which is only expandable to 2GB of ram. I currently have 1GB and would like to upgrade to 2GB. I was wondering if I'm supposed to buy just a stick of 1GB of ram and stick it in or if the ram has to be the same and I would be required to buy 2x1GB sticks? Also does anyone know the lowest latency 2x1GB ram combo? Thanks.
