Intel GA-N650SLI-DS4L Setup of an SLI Scalable Link Interface Configuration, Before You Begin

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 SLI-ready PCI ExpressTM graphics cards! This section provides instructions on configuring an SLI system.

A. Before You Begin

1. Understanding the SLI Configuration Jumpers:

Pin 1	NV_SLI6
	Pin 1

Pin 1	NV_SLI4 NV_SLI5	JP1
Pin 1	NV_SLI3

Pin 1

NV_SLI1 NV_SLI2

Normal Mode

•Normal Mode (Pins 2-3 Close, Default Setting):

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 2-3, as shown in the illustration above.

•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-

Pin 1

Pin 1

NV_SLI6

NV_SLI4 NV_SLI5

Pin 1 JP1

capable PCIe x16 graphics cards of the

same model to enable SLI functionality.

2. Independent PCI x8 slots: Use the two

PCIe x16 slots as two independent PCIe

x8 slots.

Pin 1	NV_SLI3
Pin 1
NV_SLI1	NV_SLI2
	SLI Mode

To enable SLI mode, all the jumper caps on the SLI configuration jumpers should be placed on pins 1-2 as shown in the illustration to the upper-right.

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.
