•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.

•Do not place the computer system on an uneven surface.

•Do not place the computer system in a high-temperature or wet 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

3/4)CPU_FAN/SYS_FAN1/2/3(FanHeaders)

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.

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.

The front panel design may differ by chassis. A front panel module mainly consists of power switch,

reset switch, power LED, hard drive activity LED, speaker and etc. When connecting your chassis

front panel module to this header, make sure the wire assignments and the pin assignments are

matched correctly.

8) F_PANEL(FrontPanelHeader)

Connect the power switch, reset switch, speaker, chassis intrusion switch/sensor and system status indicator

on the chassis to this header according to the pin assignments below. Note the positive and negative pins

before connecting the cables.

toChapter2,"BIOSSetup,""Power,"formoreinformation).

•SPEAK(Speaker, Orange):

Connects to the speaker on the chassis front panel. The system reports

system startup status by issuing a beep code. One single short beep

will be heard if no problem is detected at system startup.

•PLED/PWR_LED(Power LED, Yellow/Purple):

Connects to the power status indicator

on the chassis front panel. The LED is on

when the system is operating. The LED is

off when the system is in S3/S4 sleep state

or powered off (S5).

•HD (Hard Drive Activity LED, Blue):

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.

•RES(ResetSwitch,Green):

Connects to the reset switch on the chassis front panel. Press the reset switch to restart the computer if the

computerfreezesandfailstoperformanormalrestart.

•CI (Chassis Intrusion Header, Gray):

Connects to the chassis intrusion switch/sensor on the chassis that can detect if the chassis cover has been

removed. This function requires a chassis with a chassis intrusion switch/sensor.

•NC (Orange): No Connection.

panel audio module to this header. Make sure the wire assignments of the module connector match the

pin assignments of the motherboard header. Incorrect connection between the module connector and the

motherboard header will make the device unable to work or even damage it.

Some chassis provide a front panel audio module that has separated connectors on each wire instead

of a single plug. For information about connecting the front panel audio module that has different wire

assignments, please contact the chassis manufacturer.

Chapter2 BIOSSetup

BIOS (Basic Input and Output System) records hardware parameters of the system in the CMOS on the

motherboard. Its major functions include conducting the Power-On Self-Test (POST) during system startup,

saving system parameters and loading operating system, etc. BIOS includes a BIOS Setup program that allows

theusertomodifybasicsystemcongurationsettingsortoactivatecertainsystemfeatures.

When the power is turned off, the battery on the motherboard supplies the necessary power to the CMOS to

keepthecongurationvaluesintheCMOS.

To access the BIOS Setup program, press the <Delete> key during the POST when the power is turned on.

To upgrade the BIOS, use either the GIGABYTE Q-Flash or @BIOS utility.

•Q-Flash allows the user to quickly and easily upgrade or back up BIOS without entering the operating system.

•@BIOS is a Windows-based utility that searches and downloads the latest version of BIOS from the Internet

and updates the BIOS.

•BecauseBIOSashingispotentiallyrisky,ifyoudonotencounterproblemsusingthecurrentversionofBIOS,

itisrecommendedthatyounotashtheBIOS.ToashtheBIOS,doitwithcaution.InadequateBIOSashing

may result in system malfunction.

•It is recommended that you not alter the default settings (unless you need to) to prevent system instability or other

unexpected results. Inadequately altering the settings may result in system's failure to boot. If this occurs, try to

cleartheCMOSvaluesandresettheboardtodefaultvalues.(Refertothe"LoadOptimizedDefaults"sectionin

this chapter or introductions of the battery/clear CMOS jumper in Chapter 1 for how to clear the CMOS values.)

2-1 Startup Screen

The following startup Logo screen will appear when the computer boots.

(Sample BIOS Version: D2)

Function Keys

•When the system is not stable as usual, select the LoadOptimizedDefaults item to set your system to its defaults.

•The BIOS Setup menus described in this chapter are for reference only and may differ by BIOS version.

There are two different BIOS modes as follows and you can use the <F2> key to switch between the two modes.

The Classic Setup mode provides detailed BIOS settings. You can press the arrow keys on your keyboard to move

among the items and press <Enter> to accept or enter a sub-menu. Or you can use your mouse to select the

item you want. Easy Mode allows users to quickly view their current system information or to make adjustments

foroptimumperformance.InEasyMode,youcanuseyourmousetomovethroughcongurationitems.
