i have a mid 2009 pre unibody macbook. It can recognize up to 6 gigs of ram with a 4gb and a 2gb. my question is what would be faster 4gb with matching 2gb modules or 6gb with mismatched modules?
I have the same MacBook as your currently running a 2x2GB matched pair. There is definitely a performance boost running this as opposed to the 6GB configuration.
However I have read on here and the apple forum that these mid 2009 can run with 8GB installed. I will be doing this upgrade within the next week so I will be sure to report back with how it goes.
im 99% positive that it wont recognize more than 6. you can install 8 but it wont recognize more than 6.
RAM is now on order should be here for the weekend![]()
