1-6 Setup of SLI (Scalable Link Interface) Configuration

NVIDIA nForce4 SLI offers blistering graphics performance with the ability to bridge two NVIDIA SLIready PCI ExpressTM graphics cards! The SLI design takes advantage of the increased bandwidth of the PCI ExpressTM bus architecture, features hardware and software innovations within NVIDIA GPU (graphics processing unit) and the NVIDIA nForce4 chipset. Together, the NVIDIA SLI technologies work seamlessly to allow two graphics cards to operate in parallel and share the work and deliver heartpounding PC performance. This section introduces steps to configure an SLI system on the GA-K8N Ulra-SLI/GA-K8N Pro-SLI/GA-K8N-SLI motherboard.

Before You Begin--

I. Understanding the GIGABYTE SLI switch module: You can find an SLI switch module socket inserted with an SLI switch module between the first and second PCIE x 16 slots. The SLI switch module has gold edge connectors on the top and bottom of it. One connector is SLI Mode and the other is Normal Mode. Normal Mode: Only the first PCIE x 16 slot is available and can operate at up to x 16 in Normal Mode.

SLI Mode: In SLI Mode, the two PCIE x 16 slots can run in two modes. You can either use them as two

individual x 8 slots or install two SLI-ready PCIE x 16 cards (Example: GIGABYTE GV-NX66T128D)

of the same model and link them together with an SLI bridge connector to enable SLI function to provide

enhanced performance.

To change to a mode, you need to insert the swtich module into the switch socket with the gold edge

connector on the top. As not all PCIE slots are available while in SLI or Normal Mode, please refer to

the table below to check PCIE slots available in SLI or Normal Mode before installation.

PCIE_1 PCIE_16_1 PCIE_2 PCIE_16_2

SLI Mode

Normal Mode

"*" can run at up to PCIE x 8 mode.

Available Available* Not available Available*

Available Available Available Not available

1. Installing a device to a PCIE slot when it's not available might damage the system.

2. We do not recommend removing the SLI switch module from the motherboard because

in that case, all PCIE slots will not be available except for the PCIE_16_1 slot, and the slot

can be used only as a PCIE x 8 slot. II. Power Requirements: The exact power requirements will depend on your overall system configurations. You need a power supply that can provide sufficient and stable power to your system and the two SLI graphics cards. Please refer to the table below to check recommended power for different systems.

Enabling SLI Mode--

Follow the steps below to enable SLI Mode. Note that as the switch module is inserted in the socket in the Normal Mode direction by factory default, the first step to enable SLI mode on your system is to take out the module from the socket and insert it in the SLI Mode direction.

Step 1: Gently spread the retaining clips of the socket and the

module may then be removed from the socket. Hold the module by the edges and lift it away from the socket.

Step 2: Position the SLI Mode side of the module above the socket at

a 25o angle. Align the small notch at the top edge of the module with the key in the socket.

Step 3: Insert the top edge of the module into the socket. Make sure

the gold edge connectors are fully inserted.

Step 4: Gently press down on the two ends of the module until it is

locked in place by the socket clips. (You should hear a "click" when the module is attached.)

Connecting Two Graphics Cards: Step 1: Observe the steps in "1-5 Installation of Expansion Cards" on

page 16 and install two SLI-ready graphics cards of the same model to the PCIE_16_1 and PCIE_16_2 slots.

Step 4: Plug the display cable into either one of the two

graphics cards for display output. If you plug the display cable to the card on the PCIE_16_1 slot, make sure to set Init Display First in BIOS Setup to PEG; if you plug the display cable to the card on the PCIE_16_2 slot, set Init Display

First to PEG(Slot2).

English

Graphics Card Driver Setting: Step 1: After installing graphics card driver in operating

system, right-click the NVIDIA icon in your system tray and then select NVIDIA Display. The NVIDIA control panel will appear.

Step 2: Select SLI multi-GPU from the side menu and

then select the Enable SLI multi-GPU checkbox in the SLI multi-GPU dialog box. System will restart after you click Apply. Then the SLI configuration is completed.

3/4/5) CPU_FAN / SYS_FAN/ PWR_FAN (Cooler Fan Power Connector)

The cooler fan power connector supplies a +12V power voltage via a 3-pin power connector and possesses a foolproof connection design. Most coolers are designed with color-coded power connector wires. A red power connector wire indicates a positive connection and requires a +12V power voltage. The black connector wire is the ground wire (GND). Please remember to connect the power to the cooler to prevent system overheating and failure. Caution! Please remember to connect the power to the CPU fan to prevent CPU overheating and failure.
