OR! You could just go to Crucials website and use their memory compatibility finder. It will find the ram that is compatible for you because when it comes to laptops the ram sometimes needs to be specific.
lol are you guys serious? even if not for anything else, for the OP to learn about what he is doing.
Instead of giving him tools for him to work out what he wants, and geting some knowledge on the way, you are telling him to rely on someone else's judgement (even if it is from crucial. It could even be from the pope or god himself.) and almost don't give a crap about his equipment.
"meh this is easier. someone will do the work for me, nice".
If I want my car serviced I don't go to evening classes to learn motor mechanics, buy a load of tools, and hire a garage with a ramp. I take it to the dealer and ask people who know what they are doing to service it for me.
Same with RAM for a computer. Just go to a specialist who will tell you exactly what you need and will sell you memory guaranteed to work with that computer. I've seen far too many posts from people asking why the RAM they have bought won't work.
