Really new to the forums (joined today) so sorry if this is posted somewhere already, but I wasn't able to find a clear answer to what I wanted to know I just upgraded my stock HD to a new OCZ Agility 4 SSD last night. Very happy with the new addition! It went pretty smooth for never doing something like that before thanks to all the great comments posted by people in the forums. Wouldn't have been able to do it without that! That being said, I'm a little uncertain about my ability to upgrade to 16GB of RAM. I found several companies Corsair, Patriot, Centon, etc with 16GB of ram for around $99... However, all of them (except Centon) state 2011 MBP and later as being compatible. That being said, I've noticed others saying they've successfully upgraded to 16GB of ram in their 2009 MBP here in the forums, so my question is this. Will any of these mentioned above work in my 13" 2009 MBP? For example: Centon, 16GB DDR3-1333 (PC3-10600) CL9 Dual Channel laptop memory (2x8GB modules) or is there truly an 8GB ceiling on the ram in this year MBP/processor?
