    I just installed windows 7 on my sony z. The notebook has nvidia geforce 9300m gs which is a 512MB. However, when I check the screen properties on windows 7 it show that the video card is only 256MB.

    Is that a driver problem ? (I haven't install any new driver yet)
    and how can I fix it ?

    thx

    512MB? The Intel Graphics Media Accelerator 4500MHD has up to 256MB. The newer Z's have Nvidia graphics up to 2GB but that's due to shared architecture with the main memory.

    Never heard of 512MB. Which Z model do you have?

    There are two versions of Z reguarding the video memory. One has shared memory 128MB and the other 256MB, so I think you are good.

    I'm pretty sure all Vaio Z's nVidia 9300GS has either 128MB or 256MB of dedicated VRAM (depending on model) and not shared from system RAM. AFAIK the Intel graphics however use shared memory from system RAM and not using nVidia's VRAM.

    The guy is probably confused as hell! I think its safe to say that there is no 512MB version. Windows is reading your memory correctly.

    Just to confirm, the GeForce 9300M GS supports a maximum of 256MB

    Maybe you were looking at Intel 4500HD's VRAM, because you can select it as 256MB, 512MB, etc.
