Chapter 1 Hardware Installation
1-1 Installation Precautions
The motherboard contains numerous delicate electronic circuits and components which can become
damagedasaresultofelectrostaticdischarge(ESD).Priortoinstallation,carefullyreadtheuser'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
componentssuchasamotherboard,CPUormemory.IfyoudonothaveanESDwriststrap,
keepyourhandsdryandrsttouchametalobjecttoeliminatestaticelectricity.
•Prior to installing the motherboard, please have it on top of an antistatic pad or within an
electrostatic shielding container.
•Before connecting or 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.
•Donotplacethecomputersystemonanunevensurface.
•Donotplacethecomputersysteminahigh-temperatureorwetenvironment.
•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,pleaseconsultacertiedcomputertechnician.
•If you use an adapter, extension power cable, or power strip, ensure to consult with its installation
and/or grounding instructions.

1-3 Installing the CPU
ReadthefollowingguidelinesbeforeyoubegintoinstalltheCPU:
•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.
•DonotturnonthecomputeriftheCPUcoolerisnotinstalled,otherwiseoverheatinganddamage
of the CPU may occur.
•SettheCPUhostfrequencyinaccordancewiththeCPUspecications.Itisnotrecommended
thatthesystembusfrequencybesetbeyondhardwarespecicationssinceitdoesnotmeetthe
standard requirements for the peripherals. If you wish to set the frequency beyond the standard
specications,pleasedosoaccordingtoyourhardwarespecicationsincludingtheCPU,graphics
card, memory, hard drive, etc.
Installing the CPU
Locate the alignment keys on the motherboard CPU socket and the notches on the CPU.
Do not remove the CPU socket cover before inserting the CPU. It may pop off from the load
plate automatically during the process of re-engaging the lever after you insert the CPU.
1-4 Installing the Memory
Readthefollowingguidelinesbeforeyoubegintoinstallthememory:
•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.

Connector)
With the use of the power connector, the power supply can supply enough stable power to all the components
onthemotherboard.Beforeconnectingthepowerconnector,rstmakesurethepowersupplyisturned
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 power connector mainly supplies power to the CPU. If the 12V power connector is not connected,
the computer will not start.
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 the
required power, the result can lead to an unstable or unbootable system.

All fan headers on this motherboard are 4-pin. 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.
•Be sure to connect fan cables to the fan headers to prevent your CPU and system from
overheating. Overheating may result in damage to the CPU or the system may hang.

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.)

•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.
