It doesn't, where did you get that info? Pic? Video?

"When I configure two graphics cards in SLI mode, do the graphics cards work together to create double the memory size?

No. In SLI mode, each graphics card uses its own frame buffer memory to render a 3D application. The operating system will report a graphics card frame buffer memory size that is found on a single graphics board."

I think you misread the info.

+Rost Skak This video was made with FXAA and all settings on very high because the 660 has 2GB of video memory and MSAA is too heavy, do not recommend it. better use DSR and keep FXAA if 1080p is not enough (with 1440p 40fps)"

2gb of Vram. 😛

No VRAM does not stack at all in SLI. This is supposed to change with Direct X 12 in Windows 10
