I know that 2008 could only take 6GB of ram officially and unoffically took 8GB. I was wondering if something similar is the same with the 2009 Macbook pros.
 
yes. it'll work fine.

Are you sure? The OP is talking about 2009 MBPs, not 2011 MBPs, the first ones to be confirmed working with 16GB RAM, though 8GB SO-DIMM modules just became available this year.
Coincidentally I thought about this today too, as I have a 2009 MBP and would like to have more than 8GB RAM sometimes,, which is the official maximum, when Lameville gets too demanding.

Where on MacRumors site is this type of information. They had a extensive information area. Now there is nothing but news and forums. Has it moved or is it just me?
 
The only Macbook Pros that will support 16 GB of RAM are the new Sandy Bridge models, known as "Early 2011" models. Any Early 2011 model, including the base 13", can use 16 GB.

If you look at the Intel spec sheets (I'm sorry I don't have the links handy), you'll see that the maximum supported in earlier chipsets is 8 GB. Any unibody Macbook Pro can use 8 GB RAM (the earliest unibody MBPs need a firmware update, but support 8 GB once updated).

So, to the OP, no--your MBP will not support 16 GB RAM. 8 GB is the maximum your machine will support.

Hope that helps!
 
Thanks. I was hoping for 16GB for later down the road to keep from buying another machine. Should still get 5 years out of it I think.
