1-1 Installation Precautions
The motherboard contains numerous delicate electronic circuits and components which can
become damaged as a result of electrostatic discharge (ESD). Prior to installation, carefully read
the user's manual and follow these procedures:
• Prior to installation, do not remove or break motherboard S/N (Serial Number) sticker or
warranty sticker provided by your dealer. These stickers are required for warranty validation.
• Always remove the AC power by unplugging the power cord from the power outlet before
installing or removing the motherboard or other hardware components.
• When connecting hardware components to the internal connectors on the motherboard,
make sure they are connected tightly and securely.
• When handling the motherboard, avoid touching any metal leads or connectors.
• It is best to wear an electrostatic discharge (ESD) wrist strap when handling electronic com-
ponents such as a motherboard, CPU or memory. If you do not have an ESD wrist strap,
keepyourhandsdryandrsttouchametalobjecttoeliminatestaticelectricity.
• Prior to installing the motherboard, please have it on top of an antistatic pad or within an
electrostatic shielding container.
• Before unplugging the power supply cable from the motherboard, make sure the power sup-
ply has been turned off.
• Before turning on the power, make sure the power supply voltage has been set according to
the local voltage standard.
• Before using the product, please verify that all cables and power connectors of your hard-
ware components are connected.
• To prevent damage to the motherboard, do not allow screws to come in contact with the
motherboard circuit or its components.
• Make sure there are no leftover screws or metal components placed on the motherboard or
within the computer casing.
• Do not place the computer system on an uneven surface .
• Do not place the computer system in a high-temperature environment.
• Turning on the computer power during the installation process can lead to damage to sys-
tem components as well as physical harm to the user.
• If you are uncertain about any installation steps or have a problem related to the use of the
product,pleaseconsultacertiedcomputertechnician.

(Note 1) Based on standard PC architecture, a certain amount of memory is reserved for system usage and
therefore the actual memory size is less than the stated amount. For example, 4 GB of memory size
will instead be shown as 3.xx GB during system startup.
(Note2) Tocongure7.1-channelaudio,youneedconnectwiththeportofHDAudiostandardviafront
panel and enable the multi-channel audio feature through the audio driver.
(Note 3) Whether the CPU fan speed control function is supported will depend on the CPU you install.
(Note 4) Available functions in EasyTune may differ by motherboard model.
(Note 5) Due to the hardware limitation, you must install the Intel® Core™2 Extreme/Core™2 Quad/
Core™2 Duo/Pentium Dual-Core/Celeron Dual-Core/Celeron 400 Series CPU to enable support for
Easy Energy Saver
1-3 Installing the CPU and CPU Cooler
Read the following guidelines before you begin to install the CPU:
• Make sure that the motherboard supports the CPU.
(Go to GIGABYTE's website for the latest CPU support list.)
• Always turn off the computer and unplug the power cord from the power outlet before installing
the CPU to prevent hardware damage.
• Locate the pin one of the CPU. The CPU cannot be inserted if oriented incorrectly. (Or you may
locate the notches on both sides of the CPU and alignment keys on the CPU socket.)
• Apply an even and thin layer of thermal grease on the surface of the CPU.
• Do not turn on the computer if the CPU cooler is not installed, otherwise overheating and dam-
age of the CPU may occur.
• SettheCPUhostfrequencyinaccordancewiththeCPUspecications.Itisnotrecommended
thatthesystembusfrequencybesetbeyondhardwarespecicationssinceitdoesnotmeetthe
standard requirements for the peripherals. If you wish to set the frequency beyond the standard
specications,pleasedosoaccordingtoyourhardwarespecicationsincludingtheCPU,graph-
ics card, memory, hard drive, etc.

1-4 Installing the Memory
Read the following guidelines before you begin to install the memory:
•Make sure that the motherboard supports the memory. It is recommended that memory of the
same capacity, brand, speed, and chips be used.
(Go to GIGABYTE's website for the latest supported memory speeds and memory modules.)
•Always turn off the computer and unplug the power cord from the power outlet before installing
the memory to prevent hardware damage.
•Memory modules have a foolproof design. A memory module can be installed in only one direc-
tion. If you are unable to insert the memory, switch the direction.
1-4-1 Dual Channel Memory Conguration
This motherboard provides two DDR2 memory sockets and supports Dual Channel Technology.
The two DDR2 memory sockets are divided into two channels and each channel has one memory socket as
following:
Channel 0: DDRII1
Channel 1: DDRII2
DDRII1
DDRII2
Due to chipset limitation, read the following guidelines before installing the memory in Dual Channel mode.
1. Dual Channel mode cannot be enabled if only one DDR2 memory module is installed.
2. When enabling Dual Channel mode with two memory modules, it is recommended that memory of
the same capacity, brand, speed, and chips be used.
1-5 Installing an Expansion Card
Read the following guidelines before you begin to install an expansion card:
•Make sure the motherboard supports the expansion card. Carefully read the manual that came
with your expansion card.
•Always turn off the computer and unplug the power cord from the power outlet before installing
an expansion card to prevent hardware damage.

components onthe motherboard. Before connecting thepower connector, rstmake sure thepower
supply is turned off and all devices are properly installed. The power connector possesses a foolproof
design. Connect the power supply cable to the power connector in the correct orientation. The 12V

To meet expansion requirements, it is recommended that a power supply that can withstand high
power consumption be used (500W or greater). If a power supply is used that does not provide

3/4) CPU_FAN/SYS_FAN (Fan Headers)
The motherboard has a 4-pin CPU fan header (CPU_FAN) and a 3-pin (SYS_FAN) system fan header.
Most fan headers possess a foolproof insertion design. When connecting a fan cable, be sure to connect
it in the correct orientation (the black connector wire is the ground wire). The motherboard supports CPU
fan speed control, which requires the use of a CPU fan with fan speed control design. For optimum heat
dissipation, it is recommended that a system fan be installed inside the chassis.

low level, or the CMOS values may not be accurate or may be lost.
You may clear the CMOS values by removing the battery:
1. Turn off your computer and unplug the power cord.
2. Gently remove the battery from the battery holder and wait for one
minute. (Or use a metal object like a screwdriver to touch the positive
and negative terminals of the battery holder, making them short for 5
seconds.)
3. Replace the battery.
4. Plug in the power cord and restart your computer.
•Always turn off your computer and unplug the power cord before replacing the battery.
•Replace the battery with an equivalent one. Danger of explosion if the battery is replaced with
an incorrect model.
•Contact the place of purchase or local dealer if you are not able to replace the battery by your-
self or uncertain about the battery model.
•When installing the battery, note the orientation of the positive side (+) and the negative side (-)
of the battery (the positive side should face up).
•Used batteries must be handled in accordance with local environmental regulations.

Connects to the speaker on the chassis front panel. The system reports system startup status by is-
suing a beep code. One single short beep will be heard if no problem is detected at system startup. If
a problem is detected, the BIOS may issue beeps in different patterns to indicate the problem.
•HD (Hard Drive Activity LED)
Connects to the hard drive activity LED on the chassis front panel. The LED is on when the hard drive
is reading or writing data.
