More Memory on GPU of Window 7 of than Window XP :S

Hello Personall gamespots :) Hey

I am not really experience problem, to be exact, but of confusion ? My compunta has GPU of Geforce 7600GS w/512MB VRAM. I use to run XP but now try out Windows 7 x64 version. Now when run dxdiag it is of show these:

Is correct drivers and thing but is show of these much Total Memory. I am certain this card has of 512MB memory not 1272MB. What is going on?

Also, does it trick compunta into think that I really have 1272MB VRAM or not?

PS: Sorry for bad English as I am new man to it (do not worry I think of you can understand although)

i think its including memory from your mobo

All connected hardware will have discrete RAM locations that are reserved for each device, and a CPU does perform some frame processing (which number of frames the CPU does is controllable through the nVidia Control Panel).

It's not surprising to see motherboard RAM added to the RAM on a graphics card.

Okay.

Or it's just a glitch.... that they'll soon patch.

Pretty sure it's due to DX10/DX11 video memory virtualization.

It reports that way because Windows 7 (and Vista) can page video data to system memory as a virtualized extension of video memory. Obviously that space isn't being occupied when you run dxdiag (or very little of it), so it's probably just reporting with the paging cap (varies depending on your system, I guess..my GTX 260 reports as having "3690MB" with 6GB of system memory.)
