    Hi All, I'm from the Sony forums and have a question for you guys/ladies.

    I purchased ram 2 sticks of 2GB PC6400 ddr2 800 mhz for my new montevina based VAIO.

    Seeing that probably only 3.25 GB will be used, Will any of this ram run in dual channel?

    I will have a 1 stick of 1 GB ram already shipped with my VAIO, by the way.Sony wanted to charge me 50 bucks to upgrade from 1 GB to 2GB. I bought my 4 GB ram for nearly 65 dollars after rebates. Screw Sony's greediness.

    However, I do make music on my laptop and game occasionally. Would the 4 GB (I KNOW vista 32 doesn't use all of the 4 Gb) still be of some benefit or did I just blow 65 bucks?

    thanks!

    You can expect to see dual channel performance. See this thread.

    With the modern chipsets any 2 modules will give dual channel.

    Vista will use any spare RAM (up to the 3.2GB limit) for SuperFetch, whereby it pre-loads files it thinks you will use into the RAM. Once Vista's figured out your usage habits this means you favorite applications load much faster because they are already in RAM and don't have to be fetched from the HDD.

    1 stick - Single channel
    2 unequal sticks - Asymetrical dual channel
    2 equal size sticks - Symetrical (true) dual channel

    It will identify the RAM from each stick equally until it reaches it's max (3.25?) so yes dual channel.
