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.

place, and replace the computer cover.
After installation, remember to connect the power cable to your graphics
card, or the system will not boot. Do not touch the card when it's operating
to prevent system instability.
3. Plug the display cable into your graphics
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
into the DVI-I connector, then plug the monitor
Connect a flat panel

How NVIDIA® SLI™ (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.
