Appendix B. 

Configuring an SLI Configuration 

NVIDIA SLI (Scalable Link Interface) is a revolutionary technology that allows 
two XFX 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: 

 

XFX GeForce 8800 GTX  

 

XFX 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 17).
