4.1NVIDIA® Hybrid SLI® Technology

The motherboard supports the NVIDIA® Hybrid SLI® technology that includes two primary features: GeForce® Boost and HybridPower™. GeForce® Boost enhances the performance of NVIDIA discrete Graphics Process Units (dGPU) when they work with the onboard motherboard GPU (mGPU). HybridPower™ unleashes the graphics performance of the dGPU and enables low-power operation when the performance of the dGPU is not needed. You can switch from the dGPU(s) to the mGPU for a quiet, power-saving computer environment.

• Hybrid SLI technology is supported by Windows® Vista™ only.

• GeForce Boost supports up to two displays simultaneously (both connected to either the mGPU or the dGPU).

•When two or more displays are connected to both the mGPU and the dGPU, the Hybrid SLI mode is disabled and the multi-display mode is enabled. In the multi-display mode, up to four displays could be connected (up to two displays driven by the mGPU and up to two displays by the dGPU).

•HybridPower requires displays to be connected to the mGPU. HybridPower cannot be enabled when displays are driven through the dGPU.

•HybridPower and GeForce Boost are supported by certain set of dGPUs. Go to www.nvidia.com/hybridsli to learn the supported GPUs.

4.1.1System requirements

Before using Hybrid SLI, ensure if your system meets the following requirements:

For best GeForce Boost performance

• AMD Phenom 9600 CPU (operating at 1800Mhz or higher)

• 2 x 1024MB of DDR2-800 DRAM

• Discrete GPU recommended for GeForce Boost

• At least 256MB of Frame Buffer carve out for the motherboard GPU

For best HybridPower benefits

• AMD Athlon X2 3800+ CPU (operating at 1800Mhz or higher)

• 2 x 1024MB of DDR2-667 DRAM

• Discrete GPU recommended for HybridPower

• At least 256MB of Frame Buffer carve out for the motherboard GPU
