GPU vram incorrect???

[cp0020]

ok, so i have a sapphire HD 6670 with 1gig of vram. when i ran canyourunit it sayd i only had 759mb of vram... i figured it was just inaccurate but when i installed the witcher2 and the game updates it said i only had 759mb of vram also. not sure what is going on as my GPU has 1gig of vram. i have the latest 11.6 drivers.. any help? also... i have a phenom II X4 965 BE and a biostar A880G+ mobo. maybe i just have something on that is using that extra vram? please help guys lol

What operating system are you using? Is it 32-bit or 64-bit? How much system ram do you have?

windows7 ultimate 64bit 8gigs of DDR3 system ram

You have the lastest driver but have you installed the latest Hotfix?

AMD Catalyst

What does GPU-Z report?

[cp0020]

GPU-Z says the latest driver version is catalyst 11.6... not sure if that is the hotfix or not. and it says memory size 1024.

I would install the hotfix, if it's already been installed the setup program should tell you.

If GPU-Z is reporting your memory correctly then I would say canyourunit and the Witcher 2 system info collection utility is flawed.
