Appendix B. Configuring an SLI Configuration

NVIDIA SLI (Scalable Link Interface) is a revolutionary technology that allows two NVIDIA SLI graphics cards to work together to deliver incredible 3D graphics performance.

Your new motherboard can support up to three PCI Express graphics cards linked using SLI. Currently 3-way NVIDIA SLI is approved and operating on the following graphics cards:

qNVIDIA GeForce 8800 GTX

qNVIDIA GeForce 8800 Ultra

SLI Connector

NVIDIA 3-way SLI platform will also require a new SLI connector that connects the SLI headers on the GeForce GPUs (Figure 31).
