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.
SLI Mode
Normal Mode
PCIE_1 PCIE_16_1 PCIE_2 PCIE_16_2
Available Available* Not available Available*
Available Available Available Not available
"*" can run at up to PCIE x 8 mode.
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.
SLI Mode
Normal Mode
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.

K8 nForce4 SLI Series Motherboard
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 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.)
Enabling SLI Mode--
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.
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.
III. Supported Operating Systems:
Only Windows XP operating system is currrently supported by the NVIDIA SLI technology.

recommended that a power supply that can withstand high power consumption be used (300W or
greater). If a power supply is used that does not provide the required power, the result can lead to an
unstable system or a system that is unable to start.
If you use a 24-pin ATX power supply, please remove the small cover on the power connector
on the motherboard before plugging in the power cord ; otherwise, please do not remove it.

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.
