    Notice 5006 : Only compare the results with ones obtained using the same version!
    Notice 5406 : System bandwidth appears memory limited. Attempt to use higher-performance memory.

    In the User Manual-SiSoftware Sandra says...

    " Notice N5406 - System bandwidth appears to be memory limited. Generally this means that memory bandwidth is < 50% FSB bandwidth, thus CPU is starved. This generally indicates a mismatch between memory and system. Note that this does not indicate that memory timings are wrong, but the memory itself is slow.

    Fix: Use higher performance memory (e.g. DDR/2/3 or even RDRAM) or use any additional memory channels (if present) to increase memory bandwidth performance.
    "

    Now the question is...should I have to change my memory for the correct one (Pc 2700 @ 333MHz) or with these 2 x 1GB Corsair @400Mhz need to do something like overclock, change Bios or what?

    Thanks for all those results. The part of the result that interests me is the bandwidth of around 1.4GB/s. This is slow in comparison with the result in Sandra's database for the 855PM + 333MHz RAM of about 2.1GB/s, ie about 50% faster.

    The SPD data suggests that the RAM could run faster so we have to wonder whether the limitation is in the BIOS. Are there any memory options in the BIOS?

    Hi John.

    I'm pretty sure that my Bios doesnt have more options. I all ready checked it. The only options that I have are in the BOOT CONFIGURATION.
    Boot POST : Automatic or Minimal or Thorough
    Boot Speed: Compatible and 1.80GHz

    Minimal and 1.80GHz are my sets right now.

    Also there is another option in different page of the BIOS and it is Intel Stepspeed or speedstep, "dont remember"(tm): ENABLED or Disabled.

    I have it in Enabled. I tried that before in disabled and the laptop can`t run, too slow even when I play the FPS are too low that is imposible to play and starting windows takes too long.

    If you want I can take some pictures of my 7 pages of my BIOS and Post it.

    Can I do what Channelv said on this thread (see post #9)?
    http://forum.notebookreview.com/showthread.php?t=237888&highlight=d800

    Channelv words:"I had a D800 Latitude, its a good machine. I also upgraded it to DDR333 2gb memory. Now, if you search around google, you will find out that if you flash the BIOS with the Precision M60 (its exactly the same computer but with diff graphics card), you can utilize DDR333. I'd try to install the DDR333 first though to see if your D800 recognizes it (go to your BIOS to see if it is recognized and running as 333mhz). Newer revisions of the mainboard might. I flashed mine to M60 bios and it ran at 333mhz perfectly. The D800 isn't dual channel though, but I don't think that's a significant disadvantage anyways."
