I just bought this card and when I go to dxdiag it only says it has 703mb approx. total memory? Isn't it supposed to be 1024mb??

    Why? Is it a known issue on dxdiag?? I just wanna make sure it isn't a defective hardware so I could RMA immediately
  3. my 6850 only shows 734mb in dxdiag. but GPU-Z, which is more reliable, shows the full 1024.
    you can download GPU-Z here:
  4. GPU-Z is what I use. It shows all the information about the card, such as the core and the memory bus.

    It's probably just showing the RAM that is not allocated.
  5. I downloaded GPU-Z and it says 1024mb memory so I guess it's a dxdiag problem? Hmmm, weird..............
  6. Well, it looks like you have all the memory, so I wouldn't worry about it.
