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.

card; then turn on the computer and monitor.
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.
To install your new graphics card:

4. To connect an HDMI TV, use either
Method A or Method B below (depending
on your motherboard design) to enable
the S/PDIF in function for the graphics card.
It is recommended Method A be used on
motherboards that have a free S/PDIF
header.
A-1. Connect the SPDIF cable to the graphics card
A-2. Connect the SPDIF cable to the motherboard.
B-1. Connect the GIGABYTE video adapter to
the TV-Out port on the graphics card
B-2. Connect the SPDIF coaxial cable (optional)
to the video adapter and motherboard
Method B (via the coaxial S/PDIF out
jack): Connect the GIGABYTE video
adapter to the TV-Out port on the graphics
card. Insert one end of the SPDIF coaxial
cable (optional) into the S/PDIF in jack on
the adapter and the other end into the
coaxial S/PDIF out jack on your
motheboard.
Method A (via the S/PDIF out header):
Connect the provided S/PDIF cable to the
graphics card and the S/PDIF out header
on your motherboard (the red wire
connects to the S/PDIF out pin and the
black to the Ground pin).

GIGABYTE Thermal Solution Guidelines:
1. GIGABYTE established the use of silent pipes on graphics card's thermal solution, and has been
the leading company for silent thermal solution. GIGABYTE's passive thermal solution allows
system to work perfectly in chassis with 40~50 degrees Celsius through the air flow of the system.
Please beware of the other excess component or insufficient system thermal design that may
cause high system temperature. Excess high temperature will affect the passive thermal design
and thus compromising system stability.
2. GIGABYTE TECHNOLOGY's passive thermal design effectively implemented heat exchange,
radiation and convection to improve stability of the system. Please maintain passive thermal sink
at a normal and clean environment. Extra dust on heatsink may decrease the effectiveness of the
thermal design.

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 x16 PCI Express slots to scale graphics performance. The picture below shows that two
graphics cards are linked in parallel in an SLI configuration.
