    Hi there
    I have recently bought sony viao vgn FZ-21E and it came with Nvidia Geforce 8400M GT with a total memory of 831mb, dedicated 64mb and shared 767mb.
    After reading specs on nvidia website it says that 8400m GT comes with 256mb dedicated. Why does my laptop says its 64mb?.
    Some websites says Geforce 8400m GT comes with 1023mb total mem and with 256mb dedicated..but mine is 64mb...confusing? Are there two variants of 8400m GT?

    Also if I want to overclock mine it how it can be...it has windows Vista.

    can flight simulator 2004 and flight simulator X be run easily on this with 64mb dedicated or shall I return my laptop.

    To overclock get ntune or Rivatuner and get the latest driver from here

    You won't be able to play FSX on high settings, not even medium. FSX is very demanding, though it depends more on the cpu.
    But FS9 will not be a problem.
    I run FS9 with everything on "high" on my machine (see specs in sig)

    There are 3 versions, 64 128 and 256. Unfortunately the 64MB version is crippled and benches very badly, it's barely any better than the 8400M GS if at all. I honestly have no idea why Nvidia would offer such a card.

    It should be ok with flight simulator 2004 but it will struggle with FSX.

    The GT can come with a maximum of 512MB dedicated RAM but as little as a manufacturer wants to put in it (but usually not less than 64MB). It probably has 64MB of dedicated RAM and can access system RAM to share up to 1024MB (1GB) if needed.

    64MB is small, usually you want a minimum of 128MB. But the fact that it can share system RAM shouldn't make it a bottleneck other than the slower system RAM that it uses. If it were me, I'd look for a different laptop with more dedicated RAM if you are planning on running FSX, and even consider 8600m GT.

    I am afraid that many of FZ's in europe have stupid amounts of GDDR3 memory.
    Plus, Sony aren't to intelligent either on there specification pages. Not only this, but they also put down that the FZ11 series are only capable of a 2GB RAM, when the intel website with this particular chipset, says that it can support up to 4GB!!

    Overclocking increases the speed of your video card's memory, it won't magically give you additional dedicated memory.

    By stupid amounts of memory, I'm assuming too small? I agree. There can't be much of a cost difference between having 64MB or 128MB of RAM.

    As far as the memory, sometimes vendors limit the amount of memory useable in the BIOS for some reason. That's stupid too.

    I see too many times these cheap laptops that are limited to 1GB of RAM, which makes no sense to me whatsoever. I can't imaging allowing 2GB of RAM would cost more than allowing 1GB?

    My knowledge about overclocking is of a "noob" level, but can you actually overclock an 8400GT 64mb to any reasonablity?
