I recently purchased a Sony Vaio FZ160E with the T7300 2.0GHz processor. I'm looking to upgrade from 2GB 667MHz memory to 4GB.



The machine has a FSB of 800MHz. I have heard it's best to match the clock speed of the memory to the FSB. If this is true, how beneficial would it be to have PC6400 800MHz?



For that matter, would it be beneficial to upgrade from 2GB to 4GB? I use the computer mostly for downloading, movie watching, DVD ripping/writing, and web browsing.



Thanks.
