Preparing Your Computer

Computer motherboards and expansion cards contain very delicate Integrated Circuit (IC) chips. T o
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 of f 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.

English

The manufacturer assumes no liability for any damage, caused directly or indirectly, by improper
installation of any comfortable performing the installation, consult a qualified computer technician.
Damage to system components, and injury to yourself may result if power is applied during
installation.

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

Step 1: Installing Processor and Heatsink

Before installing the processor and heatsink, adhere to the following warning:

English

1.1 The installation of the processor and heatsink is performed in four main steps:
Step 1-1. Processor insertion
Step 1-2. Applying thermal grease
Step 1-3. Heatsink attachment
Step 1-4. Connecting processor fan power
These steps are described in detail in the following paragraphs.

Step 1-1. First, check the processor pins to see that none are bent. Move the socket lever to the
unlocked position as shown in Figure 1 & Figure 2.(90´ to the plane of the motherboard) prior to
inserting the processor. The A1 pin location is designated on the processor by a copper triangle that
matches up to a triangle on the socket as shown in Figure 3. Align the processor to the socket and
gently lower it into place. Do not force the processor into the socket.

1. The processor will overheat without the heatsink and/or fan, resulting in permanent
irreparable damage.

2. Never force the processor into the socket.

3. Apply thermal paste between the processor and heatsink.

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

5. 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. Please use AMD approved cooling
fan.

Figure 3. A1 pin location on the Socket and
Processor.Move the socket lever to the locked
position while holding pressure on the center of the
processor.

- 14 -GA-K8N Motherboard

Step1-2. When the processor is installed in the socket, apply thermal grease to the processor(as

shown in Figure 4) prior to installing the heatsink. AMD recommends using a high thermal
conductivity grease (such as Shin-Etsu types G751 or G749, or an equivalent product) for
the thermal interface material rather than a phase change material. Phase change materials
develop strong adhesive forces between the heatsink and processor.

Removing the heatsink under such conditions can cause the processor to be
removed from the socket without moving the socket lever to the unlocked
position and then damage the processor pins or socket contacts.

** 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.)

Figure 4. Application of Thermal Grease to the processor.

Step 1-3.Once the thermal grease has been applied to the processor, the heatsink can be attached to

the processor. Align the heatsink assembly with the support frame mating with the backer
plate standoffs as shown in Figure 5&6.

English

Step 1-4. Connect the fan power wires to the header on the motherboard as shown in Figure 7.

Hardware Installation Process

Step 2: Installing Memory Modules

English

The motherboard has 3 dual inline memory module (DIMM) sockets. The BIOS will automatically
detects memory type and size. T o 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.

Before installing the memory modules, adhere to the following warning:

1.When DIMM LED is ON, do not install / remove DIMM from socket.

2.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.

K8n_1001_q.p65 2003/9/19, ¤U¤È 05:2216

- 16 -GA-K8N Motherboard

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.

DDR Introduction

Established on the existing SDRAM 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 great evolutionary solution for the PC industry that builds on the existing SDRAM
architecture, yet make the awesome advances in solving the system performance bottleneck by doubling
the memory bandwidth. Nowadays, with the highest bandwidth of 3.2GB/s of DDR400 memory and
complete line of DDR400/333/266/200 memory solutions, DDR memory is the best choice for building
high performance and low latency DRAM subsystem that are suitable for servers, workstations, and full
range of desktop PCs.

@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 motherboard
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 TuneTM 4 Introduction

Gigabyte announces EasyTune

TM

English

Windows based Overclocking utility

EasyTune 4 carries on the heritage so as to pave the way for future generations.

and use many different hardware or BIOS tools to do "Overclock". And even with these technologies,
they still learn that it's quite a risk because the safety and stability of an "Overclock" system is
unknown. Now everything is different because of a Windows based overclocking utility "EasyTune
4" --announced by Gigabyte. This windows based utility has totally changed the gaming rule of
"Overclock". This is the first windows based overclocking utility is suitable for both normal and power
users. Users can choose either "Easy Mode" or "Advanced Mode" for overclocking at their
convenience. For users who choose "Easy Mode", they just need to click "Auto Optimize" to have
autoed and immediate CPU overclocking. This software will then overdrive CPU speed automati­cally with the result being shown in the control panel. If users prefer "Overclock" by them, there is
also another choice. Click "Advanced Mode" to enjoy "sport drive" class Overclocking user interface.
"Advanced Mode", allows users to change the system bus / AGP / Memory working frequency in
small increments to get ultimate system performance. It operates in coordination with Gigabyte
motherboards. Besides, it is different from other traditional over-clocking methods, EasyTune 4
doesn't require users to change neither BIOS nor hardware switch/ jumper setting; on the other
hand, they can do "Overclock" at easy step . Therefore, this is a safer way for "Overclock" as nothing
is changed on software or hardware. If user runs EasyTune 4 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 has been tested in EasyTune 4, user can "Save" this setting and
"Load" it in next time. Obviously, Gigabyte EasyTune 4 has already turned the "Overclock" technol­ogy toward to a newer generation. This wonderful software is now free bundled in Gigabyte
motherboard attached in driver CD. Users may make a test drive of "EasyTune 4" to find out more
amazing features by themselves.
*Some Gigabyte products are not fully supported by EasyTune 4. Please find the products sup­ported list
in the web site.
*Any "Overclocking action" is at user's risk, Gigabyte Technology will not be responsible for any
damage or instability to your processor, motherboard, or any other components.

Overclock" might be one of the most common is­sues in computer field. But have many users ever
tried it? The answer is probably "no". Because
"Overclock" is thought to be very difficult and in­cludes a lot of technical know-how, sometimes
"Overclock" is even considered as special skills
found only in some enthusiasts. But as to the ex­perts in "Overclock", what's the truth? They may
spend quite a lot of time and money to study, try

UAJ Introuction

UAJ (Universal Audio Jack) has a very smart feature: It will switch signal automatically when user
plugs his audio device to the wrong jack (Line-in/ Line-out).
That means users do not need to worry the Audio device should be plug in Line-in or Line-out
jack, the device will work perfectly after UAJ is activated.

Install Microsoft DirectX8.1 or later version before to enable UAJ support for Windows 98/98SE/
2000/ME.

PS. If UAJ couldn't work as expected, please
disable this function by pressing button
"UAJ information". And then Jack-Sense
function will awake and auto-detect if the Audio
device is plugged to the right jack (Line-in or
Line-out).

FAQ

Below is a collection of general asked questions. To check general asked questions based on a specific motherboard
model, please log on to

English

Question 1: I cannot see some options that were included in previous BIOS after updating BIOS. Why?
Answer: Some advanced options are hidden in new BIOS version. Please press Ctrl and F1 keys after entering

BIOS menu and you will be able to see these options.

Questions 2: Why is the light of my keyboard/optical mouse still on after computer shuts down?
Answer: In some boards, a small amount of electricity is kept on standby after computer shuts down and that's why
the light is still on.

Question 3: Why cannot I use all functions in EasyTune
Answer: The availability of the listed functions in EasyTune™ 4 depends on the MB chipset. If the chipset doesn't

support certain functions in EasyTune™ 4, these functions will be locked automatically and you will not be able to use
them.

Question 4: Why do I fail to install RAID and ATA drivers under Win 2000 and XP on boards that support RAID
function after I connect the boot HDD to IDE3 or IDE4 ?
Answer: First of all, you need to save some files in the CD-ROM to a floppy disk before installing drivers. You also
need to go through some rather different steps in the installation process. Therefore, we suggest that you refer to
the installation steps in the RAID manual at our website.
(Please download it at http://tw.giga-byte.com/support/user_pdf/raid_manual.pdf)

Question 5: How do I clear CMOS?
Answer: If your board has a Clear CMOS jumper, please refer to the Clear CMOS steps in the manual. If your board

doesn't have such jumper, you can take off the on-board battery to leak voltage to clear CMOS. Please refer to the
steps below:

4. Re-insert the battery to the battery holder.

5. Connect power cord to MB again and turn on power.

6. Press Del to enter BIOS and load Fail-Safe Defaults.

7. Save changes and reboot the system.

Question 6: Why does system seem unstable after updating BIOS?
Answer: Please remember to load Fail-Safe Defaults (Or Load BIOS Defaults) after flashing BIOS. However, if the

system instability still remains, please clear CMOS to solve the problem.

Question 7: Why do I still get a weak sound after turning up the speaker to the maximum volume?
Answer: Please make sure the speaker you are using is equipped with an internal amplifier. If not, please change

another speaker with power/amplifier and try again later.

Question 8: How do I disable onboard VGA card in order to add an external VGA card?
Answer: Gigabyte motherboards will auto-detect the external VGA card after it is plugged in, so you don't need to

change any setting manually to disable the onboard VGA.

Question 9: Why cannot I use the IDE 2?
Answer: Please refer to the user manual and check whether you have connected any cable that is not provided with

the motherboard package to the USB Over Current pin in the Front USB Panel. If the cable is your own cable, please
remove it from this pin and do not connect any of your own cables to it.

Question 10: Sometimes I hear different continuous beeps from computer after system boots up. What do these
beeps usually stand for?
Answer: The beep codes below may help you identify the possible computer problems. However, they are only for
reference purposes. The situations might differ from case to case.
