Hello everyone!, I have a sr 2,2 Ghz 15" MBP (Summer '07), and as I understand that unofficially that they can take 6GB of RAM, I want to upgrade it. At the moment I reside in Germany and the only module under 100eur that I found is this one: http://www.comtecedv.de/presta/product.php?id_product=859 Do you think that it will be compatible with my laptop?. Also, I heard that although the RAM is bumped in 2GB, as the modules are not matched, the final result is not that great. Can anyone comment on that?. Thanks!!!!
