I ran the direct X diagnostic tool to take a look at my graphics capabilities and it's telling me that the approximate video memory is clocked in at 4096MB. That doesn't make any sense, how is that possible?

The only thing that I can think of were that DirectX was inaccurate so I looked at the graphics statistics of my computer on CPU-Z which was included with the motherboard and that's telling me I have "negative" 1988MB. Not only is that not 4096MB, but its giving me a negative number and I know for a fact that you can't have a negative amount of memory!

The only things I can think of that would be amplifying my video memory output is the PCIe 3.0 bus, or that the motherboard is somehow including the on board video chip set with the video card which only then is only 2GB of video memory, which still has to be being amplified by something. Any suggestions?

Negative integers are just very large positive integers. – Ignacio Vazquez-Abrams Mar 26 '12 at 4:33
    
so which value should i go with then as far as total video memroy is concerned. – Tomas Spc Yaczik Mar 26 '12 at 4:42
    
Dunno. I know nothing about the DirectX diagnostic tool. – Ignacio Vazquez-Abrams Mar 26 '12 at 4:43

Have you seen this question: superuser.com/questions/354702/true-total-video-ram-size – Isxek Mar 26 '12 at 4:45
    
That extra RAM from dxdiag is located in RAM, not VRAM. If your video card actually ran out of VRAM and had to start using the shared memory, you'd notice a significant degradation in performance. – DrZoo Jan 27 at 19:43
