5.2NVIDIA® SLI™ technology

The motherboard supports the NVIDIA® SLI™ (Scalable Link Interface) technology that allows you to install multi-graphics processing units (GPU) graphics cards. Follow the installation procedures in this section.

5.2.1Requirements

•In Dual SLI mode, you should have two identical SLI-ready graphics cards that are NVIDIA® certified.

•In Triple SLI mode, you should have three identical SLI-ready graphics cards that are NVIDIA® certified.

•In Quad SLI mode, you should have four identical SLI-ready graphics cards that are NVIDIA® certified.

•Ensure that your graphics card driver supports the NVIDIA SLI technology. Download the latest driver from the NVIDIA website (www.nvidia.com).

•Ensure that your power supply unit (PSU) can provide at least the minimum power required by your system. See Chapter 2 for details.

•We recommend that you install additional chassis fans for better thermal environment.

•Visit the NVIDIA zone website (http://www.nzone.com) for the latest certified graphics card and supported 3D application list.
