1/2) ATX_12V_2X4/ATX (2x4 12V Power Connector and 2x12 Main Power Connector)
With the use of the power connector, the power supply can supply enough stable power to all the
components on the motherboard. Before connecting the power connector, first 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 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 power connectors are compatible with power supplies with 2x2 12V and 2x10 power
connectors. When using a power supply providing a 2x4 12V and a 2x12 power connector,
remove the protective covers from the 12V power connector and the main power connector on
the motherboard. Do not insert the power supply cables into pins under the protective covers
when using a power supply providing a 2x2 12V and a 2x10 power connector.

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 configuration 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 configuration values in the CMOS.
To access the BIOS Setup program, press the <Delete> key during the POST when the power is turned
on. To see more advanced BIOS Setup menu options, you can press <Ctrl> + <F1> in the main menu
of the BIOS Setup program.
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.
For instructions on using the Q-Flash and @BIOS utilities, refer to Chapter 4, "BIOS Update Utilities."
• Because BIOS flashing is potentially risky, if you do not encounter problems using the
current version of BIOS, it is recommended that you not flash the BIOS. To flash the BIOS,
do it with caution. Inadequate BIOS flashing may result in system malfunction.
• BIOS will emit a beep code during the POST. Refer to Chapter 5, "Troubleshooting," for the
beep codes description.
• 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 introduc-
tions of the battery/clearing CMOS jumper in Chapter 1 for how to clear the CMOS values.)

• Whether the system will work stably with the overclock/overvoltage settings you made is
dependent on your overall system configurations. Incorrectly doing overclock/overvoltage
may result in damage to CPU, chipset, or memory and reduce the useful life of these
components. This page is for advanced users only and we recommend you not to alter the
default settings to prevent system instability or other unexpected results. (Inadequately alter
ing the settings may result in system's failure to boot. If this occurs, clear the CMOS values
and reset the board to default values.)
• When the System Voltage Optimized item blinks in red, it is recommended that you set
the System Voltage Control item to Auto to optimize the system voltage settings.
(Note) This item is present only if you install a CPU that supports this feature.
