• Memory specs for 'Late 2009 iMac 27-inch model' from OWC macsales:

Two quality Mac-centric vendors are OWC macsales and Crucial.com. You'd still
have to identify the computer build model exactly & get quality RAM for them to work.
And note the keyway shape of the memory chips as they need to be oriented correct
in order to fully and properly fit into the slots. If they are the correct spec for your iMac.
Good luck & happy computing!
