1-6 Setup of an SLI (Scalable Link Interface) Configuration
The nVIDIA® nForce 650i SLI chipset offers blistering graphics performance with the ability to bridge two NVIDIA
A. Before You Begin
1. Understanding the SLI Configuration Jumpers:

Normal Mode
•Normal Mode (Pins
By default, the two PCIe x16 slots are set to Normal Mode, in which the PCIE_16_1 slot operates at up to x16 but the PCIE_16_2 slot is unavailable.
All the jumper caps on the SLI configuration jumpers (NV_SLI1, NV_SLI2, NV_SLI3, NV_SLI4, NV_SLI5, NV_SLI6, and JP1) are placed on pins
•SLI Mode (Pins 1-2 Close):
In SLI Mode, you may use the two PCIe
x16 slots for the following functions:
1. SLI Configuration: Install two SLI- |

To enable SLI mode, all the jumper caps on the SLI configuration jumpers should be placed on pins
2. Power Requirements:
Before installation, assure that the power supply you use is able to provide sufficient power to fully support an SLI configuration and other components in your system. We recommend a power supply that provides at least 20A 5V and 12V current and a minimum of 400W wattage. Note that the exact power requirements will depend on your overall system configurations.
3. Supported Operation Systems:
Only Windows XP and Windows Vista operating systems are currently supported by the nVIDIA® SLI technology.
