    Crucial says yes but I always find they are a coin flip.
    Thx

    No Intel laptop can run 800MHz RAM without downclocking back to 667MHz. Get either PC5300 or 6400, whichever is cheaper.

    The two are interchangeable. Yes, the PC2-6400 RAM will work, but you'll likely be paying more for the higher-speed-certified memory without being able to take advantage of it. As Greg said, it'll just run at 667Mhz anyway, so get whichever is cheapest.

    Edit - The memory and processor run at different bus speeds.

    Yep...there is no point in getting DDR2-800 unless its cheaper since it will downclock becuase of a chipset limitation.

    THe only intel laptop I know of that can use DDR-800 is the Clevo D901c since it uses desktop chipset(it uses desktop processors). I believe some AMD laptop can use DDR2-800 ram though.


    Also check out the ram deals thread(check the first and last couple of pages) for great deals on ram.

    ah good link! I was wondering if you could go 3rd party away from Dell's support hardware.
    links seem to be US shops, but once I find a name, I can see if a UK seller does it I suppose.

    Just FYI with Intel laptops (and maybe AMD to an extent): the processor FSB is 800MHz as previously mentioned, but the RAM bus speed is 667MHz.

    I just bought 4 (2x2) GB of OCZ 800Mhz DDR and it runs perfectly in my new M1330....The store I went too had 667Mhz ram as well, but for the same price ($99CDN) as the 800Mhz, and a less quality brand, so I went with the OCZ.

    It'll run - but at 667MHz.
