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, make sure the chassis is suitable for the motherboard.
•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 supply
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 hardware
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 system
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.

1-3 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 direction.
If you are unable to insert the memory, switch the direction.
•DDR3 and DDR2 DIMMs are not compatible to each other or DDR DIMMs. Be sure to install DDR3
DIMMs on this motherboard.

ADDR3memorymodulehasanotch,soitcanonlytinonedirection.Followthestepsbelowtocorrectlyinstall
your memory modules in the memory sockets.
Step 1:
Note the orientation of the memory module. Spread the retaining clips
at both ends of the memory socket. Place the memory module on the
socket.Asindicatedinthepictureontheleft,placeyourngerson
the top edge of the memory, push down on the memory and insert it
vertically into the memory socket.
Step 2:

3/4) CPU_FAN/SYS_FAN (Fan Headers)
The motherboard has a 3-pin CPU fan header (CPU_FAN) and a 4-pin system fan header (SYS_FAN).
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 speed control function requires
the use of a fan with fan speed control design. For optimum heat dissipation, it is recommended that a
system fan be installed inside the chassis.

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 yourself
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.
