Nvidia Goes For Four: Quad SLI Gaming Dissected

How Quad SLI Works, Continued

The boards are connected to each other with 10 pins. The traces run through some resistor structures and voltage regulators. We are waiting on a confirmation from Nvidia on what these 10 pins are actually for.

Each PCB comes equipped with 512 MB of frame buffer memory. Although the 2 GB of total memory sounds like heaven for extremely large textures, each core uses its own memory, so this is the same as any traditional graphics card and SLI setup.
