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 GA-8IRM 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-8IRM series (or any AGP 4X only)

motherboards, it will burn the motherboard.

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

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

specification. Therefore, AG32S will work fine with Intel 845 / 850 based

motherboards.

WARNING!

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 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.

Introduction

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.

and up to 90-degree angle.

3. Press down the CPU socket

lever and finish CPU installation.

? 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.

Pin1 indicator

2. Locate Pin 1 in the socket and look

for a (golden) cut edge on the CPU

upper corner. Then insert the CPU

into the socket.

CPU Heat Sink Installation

Hardware Installation Process

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.

2. Insert the DIMM memory module verticallyinto the

DIMM slot. Then push it down.

3. Close the plastic clip at both edges of theDIMM slots

to lock the DIMM module.

Reverse the installation steps when you wish to

remove the DIMM module.

? When STR/DIMM LED is ON, you do not install / remove DDR from socket.

Hardware Installation Process

DDR Introduction

Established on the existing SDRAM industry infrastructure, DDR (Double Data Rate) memory is a high performance and cost-effective solution that allows easy adoption for memory vendors, OEMs and system integrators.

DDR memory is a sensible evolutionary solution for the PC industry that builds on the existing SDRAM infrastructure, yet makes awesome advances in solving the system performance bottleneck by doubling the memory bandwidth. DDR SDRAM w ill offer a superior so lution and m igration 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 2.1GB 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 a nd v alue des ktop SM A sy stems. With a core voltage of only 2.5 Volts c ompa red to conventional SDRAM's 3.3 volts, DDR memory is a compelling solution for small form factor desktops and notebook applications.

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, 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.

AGP Card

Please carefully pull out the small whitedrawable 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.

@ BIOS Introduction

Gigabyte announces @ BIOS

Windows BIOS live update utility

Have you ever updated BIOS by yourself? Or like

many other people, you just know what BIOS is,

but always hesitate to update it? Because you think

updating newest BIOS is unnecessary and actually

you don’t know how to update it.

Maybe not like others, you are very experienced in BIOS updating and spend quite a lot of time

to do it. But of course you don’t like to do it too much. First, download different BIOS from website and

then switch the operating system to DOS mode. Secondly, use different flash utility to update BIOS.

The above process is not a interesting job. Besides, always be carefully to store the BIOS source

code correctly in your disks as if you update the wrong BIOS, it will be a nightmare.

Certainly, you wonder why motherboard vendors could not just do something right to save your

time and effort and save you from the lousy BIOS updating work? Here it comes! Now Gigabyte

announces @BIOS— the first Windows BIOS live update utility. This is a smart BIOS update

software. It could help you to download the BIOS from internetand update it. Not like the other BIOS

update software, it’s a Windows utility. With the help of “@BIOS’, BIOS updating is no more than a

click.

Besides, no matter which mainboard you are using, if it’s a Gigabyte’s product*, @BIOS help

you to maintain the BIOS. This utility could detect your correct mainboard model and help you to

choose the BIOS accordingly. It then downloads the BIOS from the nearest Gigabyte ftp site

automatically. There are several different choices; you could use “Internet Update” to download and

update your BIOS directly. Or you may want to keep a backup for your current BIOS, just choose

“Save Current BIOS” to save it first. You make a wise choice to use Gigabyte, and @BIOS update

your BIOS smartly. You are now worry free from updating wrong BIOS, and capable to maintain and

manage your BIOS easily. Again, Gigabyte’s innovative product erects a milestone in mainboard

industries.

For such a wonderful software, how much it costs? Impossible! It’s free! Now, if you buy a

Gigabyte’s motherboard, you could find this amazing software in the attached driver CD. But please

remember, connected to internet at first, then you could have a internet BIOS update from your

Gigabyte @BIOS.

Easy TuneIIITM Introduction

Gigabyte announces EasyTuneIII

Windows overdrive utility

“Overdrive” might be one of the most

common issues in computer field. But have many

users ever tried it? The answer is probably “no”.

Because “overdrive” is thought to be very difficult and

includes a lot of technical know-how, sometimes “over-

drive” is even considered as special skills found only in some enthusiasts.

But as to the experts in “overdrive”, what’s the truth? They may spend quite a lot of time and money

to study, try and use many different hardware and software tools to do “overdrive”. And even with these

technologies, they still learn that it’s quite a risk because the safety and stability of an “overdrive“ system

is unknown.

Now everything is different because of a Windows overdrive utility EasyTuneIII— announced by

Gigabyte. This utility has totally changed the gaming rule of “overdrive”. This is the first overdrive utility

suitable for both normal and power users. Users can choose either “Easy Mode” or “Advanced Mode”

to run “overdrive” at their convenience. For users who choose “Easy Mode”, they just need to click

“Auto Optimize” to have auto and immediate CPU overclocking. This software will then overdrive CPU

speed automatically with the result being shown in the control panel. If someone prefers to “overdrive” by

oneself, there is also another choice. Click “Advanced Mode” to enjoy “sport drive” class overclocking.

In “Advanced Mode”, one can change the system bus speed in small increments to get ultimate system

performance. And no matter which mainboard is used, if it’s a Gigabyte’s product*, EasyTuneIII helps to

perform the best of system.

Besides, different from other traditional over-clocking methods, EasyTuneIII doesn’t require users to

change neither BIOS nor hardware switch/ jumper setting; on the other hand, they can do “overdrive” at

only one click. Therefore, this is a safer way for “overdrive” as nothing is changed on software or

hardware. If user runs EasyTuneIII over system’s limitation, the biggest lost is only to restart the

computer again and the side effect is then well controlled. Moreover, if one well-performed system speed

been tested in EasyTuneIII, user can “Save” this bus speed and “Load” it in next time. Obviously,

Gigabyte EasyTuneIII has already turned the “overdrive” technology toward to a newer generation.

This wonderful software is now free bundled in Gigabyte motherboard attached driver CD. Users

may make a test drive of “EasyTuneIII” to find out more amazing features by themselves.
