The gaming graphics score is based on the primary graphics adapter. If this system has linked or multiple graphics adapters, some software applications may see additional performance benefits.

b666, welcome to the Seven Forums.

The short and simple answer is you don't. That and you wouldn't want to as despite the speed of system ram, it is still slower than what is on the video card. The 256 MB on the card is all you get, and the only way to increase it is to buy a card with more on it.
