Weird VRAM reading

Ok this sort of just threw me off. I have the 330m gt with 256mb of vram but when I go to check how much I have on my computer it is showing 1.1gb VRAM😱 Is my comp using the leftover RAM not usable by the 32bit OS (Win7) and tricking itself into thinking it has extra VRAM?
 
I had the same thing happen on my mid 2007 mbp. It was reading my 8600m gt with 128mb of vram as having 512mb, i figured it is probably just reading some shared system/video memory somewhere.
