Installing new RAM. Which kind (choice of 3) and compatibility issues?

[Bkid]

So yeah, I'm deciding to upgrade the RAM on my notebook:  http://www.newegg.com/Product/Product.aspx?Item=N82E16834220182

I'm not sure which I should get (I'm leaning toward Patriot), and also I need to MAKE SURE that it's compatible.

go to www.crucial.com and use their memory tool. They'll tell you what kind of memory that is compatible. So you can just simply find out exactly what memory type you need.
