    That's what pcwizard 2008 says about my RAM

    is my ram sticks running at 333mhz? o_O

    Dual data rate -> 666MHz /million operations per second

    so because it's dual channel it works at 666mhz?

    Also if i bought 2x2gb at 800mhz would i see an improvement in gaming? i was playing cod4 today it was a little laggy on 1440x900 ;P

    No, because it's dual channel you actually get 666x2mhz.
    Because it's DDR, dual data rate, it's 666(667)mhz.

    Inspiron 1720 uses the P965M chipset, which has a max memory speed of 667mhz. If you bought PC2-6400 (800mhz) it would downclock to 667mhz. So it won't really be an upgrade in speed terms. Just quantity. If you don't currently use over 2GB of RAM, it won't make any difference at all.

    Even if it would run at 800mhz, it wouldn't make a difference.

    im assuming you mean for you lappy. and judging by your setup you cannot fully use the 800mhz due to chipset limitations. but just upgrading for 2-4 will help slightly. it will help vista run better.

    Even if your notebook supported DDR2-800, you would not see any improvements in performance.

    There was an article I found before and the result was around 2-3FPS was gained (also assuming the CPU had a bus speed >= 800MHz). Perhaps because the fsb and ram speeds were the same speed, but that and 800mhz ram doesn't apply here.

    I don't have a link to it unfortunately.
