Expansion cards contain very delicate Integrated Circuit (IC) chips. To
protect them against damage from static electricity, you should follow some
precautions whenever you work on your computer.
1. Turn off your computer and unplug power supply.
2. Use a grounded wrist strap before handling computer components. If you do not have
one, touch both of your hands to a safely grounded object or to a metal object, such as
the power supply case.
3. Place components on a grounded antistatic pad or on the bag that came with the
components whenever the components are separated from the system.
The card contains sensitive electric components, which can be easily damaged by static
electricity, so the card should be left in its original packing until it is installed.
Unpacking and installation should be done on a grounded anti-static mat. The operator
should be wearing an anti-static wristband, grounded at the same point as the anti-static
mat.
Inspect the card carton for obvious damage. Shipping and handling may cause damage
to your card. Be sure there are no shipping and handling damages on the card before
proceeding.
DO NOT APPLY POWER TO YOUR SYSTEM IF IT HAS BEEN DAMAGED ON
THE CARD.
In order to ensure your graphics card working correctly, please use official
Gigabyte BIOS only. Use none official Gigabyte BIOS might cause problem
on the graphics card.

2.2. Hardware Installation
Installing Your graphics card.
Now that you have prepared your computer, you are ready to install your graphics accelerator
card.
To remove the existing graphics card:
1. Power off the computer and monitor, then
disconnect the display cable from the back
of your computer.
2. Remove the computer cover. If necessary,
consult your computer's manual for help in
removing the cover.
3. Remove any existing graphics card from
your computer.
Or, if your computer has any on-board
graphics capability, you may need to disable
it on the motherboard. For more information,
please see your computer documentation.
To install your new graphics card:
1. Locate two PCI Express x 16 slots. If
necessary, remove the metal covers from
the slots; then align your graphics card with
the PCI Express x 16 slots, and press it in
firmly until the card is fully seated.
* Please make sure that the gold edge connectors of the graphics card is securely inserted.

2. Replace the screws to fasten the card in
place, and replace the computer cover.
3. Plug the display cable into your graphics
card; then turn on the computer and monitor.
The graphics card provides two DVI-I
connectors, to connect a flat panel directly to
your graphics card, use the DVI-I connector.
To connect a VGA monitor to the DVI-I
connector, plug the DVI-I to D-sub adapter
intotheDVI-I connector, thenplugthe monitor
cable into the adapter.
You are now ready to proceed with the installation of the graphics card driver. Please refer
to next chapter for detailed instructions.
To TV/VCR
When installing the graphics card, do not push
down the heat pipe. This may displace the heat
pipe and cause bad contact between the GPU
and thermal pad as well as affect the heat
dissipation. To avoid system instability, do not
touch the graphics card when it is runnnig .
To Flat Panel Display
Connect a flat panel
Connect a VGA monitor via DVI-I to D-sub adapter

How NVIDIA® SLITM (Scalable Link Interface) technology works:
In an SLI configuration, two SLI-ready graphics cards of the same model and the same
manufacturers are connected together via SLI bridge connector in a system that provides
two x 16 PCI Express slots to scale graphics performance. The picture below shows that two
graphics cards are linked in parallel in an SLI configuration.
Precautions:
The GV-NX76T256D-RH are powered by GIGABYTE's Silent Pipe II technology, which
provides the following features:
•Proprietary front-flow thermal module
•High-precision die-casting forming design
•Natural convection design
•SLI and soundless optimization
•High performance heatpipe with sintered
powder wicks
•Design for heavy 3D performance loading
•Integrated architecture design
The Silent-Pipe II technology features the silent heatpipe design. The Silent-Pipe II technology artfully
uses the temperature difference between the inside and outside of chassis and spreads out the surplus
heat efficiently, creating natural system convection. When using Silent Pipe II graphics cards to set up
an SLI configuration, please do close your system chassis in order to achieve optimal thermal
performance. For more information about the hardware configuration of an SLI system, please refer to
motherboard user manual.
