What is NVIDIA SLI Technology?
NVIDIA® SLI™ technology is a revolutionary platform innovation that allows you to intelligently scale graphics performance by combining multiple NVIDIA graphics solutions in a single system with an NVIDIA nForce® SLI media and communications processor (MCP).

How Does SLI Technology Work?
Using proprietary software algorithms and dedicated scalability logic in each NVIDIA graphics processing unit (GPU) and MCP, NVIDIA SLI technology delivers up to twice the performance of a single graphics solution.


NVIDIA SLI-Ready Solutions

NVIDIA SLI-Ready components are backed by a rigorous testing and certification process to deliver an entire certified platform solution ensuring unmatched system stability and platform compatibility.

SLI GPUs | Graphics Cards
NVIDIA SLI GPUs deliver powerful, elegant and super-rich graphics for games and other graphics-intensive applications. Combining two NVIDIA SLI-Ready certified graphics cards (with the same GPU) in a single system with an nForce SLI MCP results in up to double the graphics performance.

NVIDIA SLI-Ready GPUs feature dedicated, built-in SLI hardware logic and take advantage of the additional bandwidth of the PCI Express bus architecture. Connected by the SLI connector* (which ships with all SLI-Ready motherboards), each GPU has a maximized connection pathway, and can leverage the second card for reaching top-speed performances. SLI Technology can scale both geometry and fill rate performance for multiple GPUs and output in both digital and analog formats for the highest image quality

SLI MCPs | Motherboards
To enable NVIDIA SLI technology in your PC, you'll also need an SLI-Ready certified motherboard with an nForce SLI MCP and two physical PCI Express x16 slots. NVIDIA motherboard partners offer nForce SLI motherboards for both AMD and Intel CPUs. Click HERE for a list of INTEL and AMD SLI-certified motherboards.

*The NVIDIA SLI connector is only used with GeForce 6600 GT products and above.
