As Dave420 said, yes it will work. They are two independent entities. They do not impact each other or cause compatibility conflicts.

VRAM (short for Video RAM), is RAM on the graphics card itself. It's strictly used by the graphics card for rendering graphics (and other stuff if you're an advanced user). RAM (system RAM) is memory used by the system for active programs.
