It doesn't mean anything. Some systems show higher than normal, some lower than normal depending on shared resources one way or another and reporting errors(mine shows 4GB on a 2GB card). Use a program like MSI Afterburner and you can actually see the amount of vram that is actually being used.
Thnx for quick response! That's good to hear, It just concerned me that win7 32 bit new how much memory it had exactly and 64 bit doesn't...Idk hopefully switching to 64 bit was a good idea because I'm running into a lot of issues unforunetly
