Can't find memory specs for both, difficult to answer this. Can you run CPU-z on your Compaq and update the question with screenshots of Memory & SPD tab ? – Sathya♦Aug 20 '10 at 1:58
I'd love to, but unfortunately I don't actually own one of these laptops... I may just end up buying the model with 4GB built in anyway, it's not that much more expensive. Thanks for your help though! – Mr. SandersAug 20 '10 at 10:52
