thanks
YES, unless there's some voodoo I don't know about. 4GB is the max of 32-bit addressing, and due to other factors you won't even be able to access more than like 3GB of it, as far as I know.
About your other stuff...some looks expensive but maybe it's good quality, I dunno. Regarding RAM, unless your RAM is superfast or something, why wouldn't you go with http://www.newegg.com/Product/Product.aspx?Item=N82E16820145184 ? It's way cheaper, not Crucial, and gets great reviews.
