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.

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.
