Review on Performance Upgrade: A-Tech Apple 2GB Module PC2-6400 800MHz RAM for iMac & MacBook Mid 2009/Early 2008 by Robert Byrd

Used to upgrade my 2008 iMac, worked great. Having no computer experience, I was able to figure out how to install these and others, and then encountered some difficulty extracting the old module (stuck for some reason). Installation was easy and really helped with the speed. this eight year old computer! If you switch to iMac, you'll never go back to PC! Great price and works great! Would buy again!
