Gigabyte GA-8IDX3 User Manual

When you installing AGP card, please make sure the

following notice is fully understood and practiced. If your
AGP card has "AGP 4X notch"(show below), please make
sure your AGP card is AGP 4X (1.5V).

Do not use AGP 2X card (3.3V) in this motherboard. It will

burn and damage the motherboard due to Intel® 845 chipset
can't support AGP 2X(3.3V).

Example 1: Diamond Vipper V770 golden finger is compatible
with 2X/4X mode AGP slot. It can be switched between AGP 2X
(3.3V) or 4X(1.5V) mode by adjusting the jumper. The factory
default for this card is 2X(3.3V). If you install this card in GA­8IDX3 series (or any AGP 4X only) motherboards without
switching the jumper to 4X mode (1.5V), it will burn the
motherboard.

Example 2: ATi Rage 128 Pro (Power Color) & SiS 305 golden
finger is compatible with 2X/4X mode AGP slot, but it supports
2X(3.3V) only. If you install this card in GA-8IDX3 series (or any
AGP 4X only) motherboards, it will burn the motherboard.

WARNING!

W ARNING!

Computer motherboards and 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. Unplug your computer when working on the inside.

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. Hold components by the edges and try not touch the IC chips, leads or connectors, or
other components.

4. Place components on a grounded antistatic pad or on the bag that came with the
components whenever the components are separated from the system.

5. Ensure that the A TX power supply is switched off before you plug in or remove the A TX

power connector on the motherboard.

Installing the motherboard to the chassis…

If the motherboard has mounting holes, but they don’t line up with the holes on the base and there are
no slots to attach the spacers, do not become alarmed you can still attach the spacers to the mounting
holes. Just cut the bottom portion of the spacers (the spacer may be a little hard to cut off, so be careful
of your hands). In this way you can still attach the motherboard to the base without worrying about short
circuits. Sometimes you may need to use the plastic springs to isolate the screw from the motherboard
PCB surface, because the circuit wire may be near by the hole. Be careful, don’t let the screw contact
any printed circuit write or parts on the PCB that are near the fixing hole, otherwise it may damage the
board or cause board malfunctioning.

 Please set the CPU host frequency in accordance with your processor’s specifications.

We don’t recommend you to set the system bus frequency over the CPU’s specification
because these specific bus frequencies are not the standard specifications for CPU,
chipset and most of the peripherals. Whether your system can run under these specific
bus frequencies properly will depend on your hardware configurations, including CPU,
Chipsets,SDRAM,Cards….etc.

Hardware Installation Process

Chapter 2 Hardware Installation Process

T o set up your computer , you must complete the following setups:

Step 1- Install the Central Processing Unit (CPU)
Step 2- Install memory modules
Step 3- Install expansion cards
Step 4- Connect ribbon cables, cabinet wires, and power supply
Step 5- Setup BIOS software
Step 6- Install supporting software tools

Step 1: Install the Central Processing Unit (CPU)

Befor You will know.....

Y ou may use the 4 screws which come with the mainboard to reinforce the support between P4

CPU heat-sink on the mainboard and chassis.

In order to follow the installation steps below; your chassis must be WILLMETTE/845 board design

compatible.
Step1: The 4 new mounting holes on the chassis

are for additional support for P4 CPU heat­sink on the mainboard.

Step2: Please remove 4 sets of plastic Push-pins

as indicated on Figure2. Remove the white
pins first, then black pins as indicated on
Figure3.

Step3:

Figure1 Figure2

Step4:Fit the 4 screws with 2 CPU retention

modules on the chassis.

CPU Heat Sink Installation

1.Align CPU and insert it

3.Slip the bracket on to the CPU retention and press both end to clip it on the retention.

2.Use qualified fan approved by Intel.

 Please use Intel approved cooling fan.
 Make sure the CPU fan power cable is plugged in to the CPU fan connector,

this completes the installation.

 Please refer to CPU heat sink user’s manual for more detail installation

procedure.

12

Hardware Installation Process

Step 2: Install memory modules

The motherboard has 3 dual in-line memory module (DIMM) sockets support 6 banks. The BIOS will
automatically detects memory type and size. T o install the memory module, just push it vertically into the
DIMM Slot .The DIMM module can only fit in one direction due to the two notch. Memory size can vary
between sockets.

SDRAM

1. The DIMM slot has two notch, so the
DIMM memory module can only fit in
one direction.

3. Close the plastic clip at both edges of the DIMM slots to lock the DIMM module.
Reverse the installation steps when you wish to remove the DIMM module.

2. Insert the DIMM memory module
vertically into the DIMM slot. Then
push it down.

 When STR/DIMM LED is ON, do not install/remove SDRAM from socket.

13

GA-8IDX3 Series Motherboard

Step 3: Install expension cards

1. Read the related expansion card’s instruction document before install the expansion card into
the computer.

2. Remove your computer’s chassis cover, necessary screws and slot bracket from the computer.

3. Press the expansion card firmly into expansion slot in motherboard.

4. Be sure the metal contacts on the card are indeed seated in the slot.

5. Replace the screw to secure the slot bracket of the expansion card.

6. Replace your computer’s chassis cover.

7. Power on the computer, if necessary, setup BIOS utility of expansion card from BIOS.

8. Install related driver from the operating system.
