Gigabyte GA-8IR2003 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(E/G) / 850(E) 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 GA-8IR2003 (or any AGP 4X only) motherboards

without switching the jumper to 4X mode (1.5V), it will burn the motherboard.

Example 2: Some ATi Rage 128 Pro graphics cards made by "Power Color",

the graphics card manufacturer & some SiS 305 cards, their golden finger is

compatible with 2X/4X mode AGP slot, but they support 2X(3.3V) only. If you

install this card in GA-8IR2003 (or any AGP 4X only) motherboards, it will

burn the motherboard.

Note : Although Gigabyte's AG32S(G) graphics card is based on ATi Rage

128 Pro chip, the design of AG32S(G) is compliance with AGP 4X (1.5V)

specification. Therefore, AG32S(G) will work fine with Intel® 845(E/G) /

850(E) based motherboards.

Please do not remove any labels on motherboard, this

Due to rapid change in technology, some of the

specifications might be out of date before publication

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.

WARNING!

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 ATX power supply is switched off before you plug in or remove the ATX 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.

"*" HT functionality requirement content :

Enabling the functionality of Hyper-Threading Technology for your computer system requires all

of the following platform components:

- CPU: An Intel

- Chipset: An Intel

- BIOS: A BIOS that supports HT Technology and has it enabled

- OS: An operation system that has optimizations for HT Technology

Chipset that supports HT Technology

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.

into the socket.

Please make sure the CPU type is supported by the motherboard.

If you do not match the CPU socket Pin 1 and CPU cut edge well, it will cause

improper installation. Please change the insert orientation.

Hardware Installation Process

Step 1-2: CPU Heat Sink Installation

English

1. Hook one end of the cooler bracket

to the CPU socket first.

2. Hook the other end of the cooler

bracket to the CPU socket.

Please use Intel approved cooling fan.

We recommend you to apply the thermal tape to provide better heat

conduction between your CPU and heatsink.

(The CPU cooling fan might stick to the CPU due to the hardening of the

thermal paste. During this condition if you try to remove the cooling fan, you

might pull the processor out of the CPU socket alone with the cooling fan, and

might damage the processor. To avoid this from happening, we suggest you to

either use thermal tape instead of thermal paste, or remove the cooling fan with

extreme caution.)

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.

Step 2: Install memory modules

The motherboard has 3 dual inline memory module (DIMM) sockets, but it can only support a maximum
of 4 banks of DDR memory. DDR slot 1 uses 2 banks, DDR slot 2 & 3 share the remaining 2 banks.
Please refer to the following tables for possible memory configurations supported. The BIOS will
automatically detects memory type and size. To install the memory module, just push it vertically into the
DIMM socket. The DIMM module can only fit in one direction due to the notch. Memory size can vary
between sockets.

DDR Introduction

high performance and cost-effective solution that allows easy adoption for memory vendors, OEMs and
system integrators.

SDRAM infrastructure, yet makes awesome advances in solving the system performance bottleneck by
doubling the memory bandwidth. DDR SDRAM will offer a superior solution and migration path from
existing SDRAM designs due to its availability, pricing and overall market support. PC2100 DDR
memory (DDR266) doubles the data rate through reading and writing at both the rising and falling edge of
the clock, achieving data bandwidth 2X greater than PC133 when running with the same DRAM clock
frequency. With peak bandwidth of 2.664GB per second, DDR memory enables system OEMs to build
high performance and low latency DRAM subsystems that are suitable for servers, workstations, high­end PC's and value desktop SMA systems. With a core voltage of only 2.5 Volts compared to
conventional SDRAM's 3.3 volts, DDR memory is a compelling solution for small form factor desktops
and notebook applications.

DDR

1. The DIMM socket has a notch, so the DIMM memory

module can only fit in one direction.

2. Insert the DIMM memory module vertically into the DIMM

socket. Then push it down.

3. Close the plastic clip at both edges of the DIMM sockets

to lock the DIMM module.

Reverse the installation steps when you wish to remove

the DIMM module.

Established on the existing SDRAM industry infrastructure, DDR (Double Data Rate) memory is a

DDR memory is a sensible evolutionary solution for the PC industry that builds on the existing

Please note that the DIMM module can only fit in one direction due to the one

notch. Wrong orientation will cause improper installation. Please change the

insert orientation.

Step 3: Install expansion 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, 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.

Please carefully pull out the small white-drawable

bar at the end of the AGP slot when you try to

install / uninstall the AGP card. Please align the

AGP card to the onboard AGP slot and press

firmly down on the slot. Make sure your AGP

card is locked by the small white-drawable bar.

English

When an AGP 2X (3.3V) card is installed the 2X_DET will light up, indicating a
non-supported graphics card is inserted. Informing users that system might not boot up
normally due to AGP 2X (3.3V) is not supported by the chipset.
