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.

Installing Your graphics card.

English

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

2. Remove the computer cover. If necessary,

disconnect the display cable from the back

of your computer.

consult your computer's manual for help in

removing the cover.

3. Remove any existing graphics card from

your computer.

GV-NX86T256H(-ZL)/512H Graphics Accelerator - 8 -

To install your new graphics card:

1. Locate the PCI Express x16 slot. If necessary,

remove the metal cover from this slot; then

align your graphics card with the PCI

Express x16 slot, 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.
To connect a flat panel directly to your
graphics card, use the DVI-I connector. To
connect a D-Sub 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

cable into the adapter.

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 PCI Express x16 slots

to scale graphics performance. The picture below shows that two graphics cards are linked in parallel

in an SLI configuration.

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.

English

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.
