Intel's latest graphics solutions can use up to 1.7GB of memory depending on the amount of system memory installed. The amount of video memory used isn't controllable by the user, its allocated dynamically. That's the reason its named DVMT, or Dynamic Video Memory Technology. The technology allows Intel graphics to only used what's needed by the application to ensure optimal system performance.

Although more video memory is generally better, there's a limit to how much a game can use. A simpler game will use less video memory than complex, high resolution games. For example, Crysis, which is arguably one of the most demanding games out there, uses roughly 500MB of video memory with all details at High.
