1 Best way to add RAM to the iMac i7 27" (late 2009)?
I'm thinking of adding 2 x 4GB chips, but do I just add 'em in there or must I change which slots they should go in to best complement the factory 2 x 2GB chips. A how to install RAM in this model would be wonderful; can you recommend one? Thanks in advance!
