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
damage of the CPU may occur.
• Set the CPU host frequency in accordance with the CPU specifications. It is not recom-
mended that the system bus frequency be set beyond hardware specifications since it
does not meet the standard requirements for the peripherals. If you wish to set the fre-
quency beyond the standard specifications, please do so according to your hardware
specifications including the CPU, graphics card, memory, hard drive, etc.

Step 3:
Place the cooler atop the CPU, aligning the
four push pins through the pin holes on the
motherboard. Push down on the push pins
diagonally.
Step 4:
You should hear a «click» when pushing down each
push pin. Check that the Male and Female push pins
are joined closely. (Refer to your CPU cooler instal-
lation manual for instructions on installing the cooler.)
Use extreme care when removing the CPU cooler because the thermal grease/tape between
the CPU cooler and CPU may adhere to the CPU. Inadequately removing the CPU cooler may
damage the CPU.
Step 5:
After the installation, check the back of the
motherboard. If the push pin is inserted as the
picture above, the installation is complete.
Step 6:
Finally, attach the power connector of the CPU
cooler to the CPU fan header (CPU_FAN) on

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 memory support list.)
• 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.
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 or four memory modules, it is recommended that
memory of the same capacity, brand, speed, and chips be used and installed in the same
colored DDR2 sockets for optimum performance.
When memory modules of different capacity and chips are installed, a message which says
memory is operating in Flex Memory Mode will appear during the POST. Intel®
Flex Memory
Technology offers greater flexibility to upgrade by allowing different memory sizes to be
populated and remain in Dual Channel mode/performance.

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 main power connector is compatible with power supplies with 2×10 power
connectors. When using a 2×12 power supply, remove the protective cover from the
main power connector on the motherboard. Do not insert the power supply cable into pins
under the protective cover when using a 2×10 power supply.

• 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.
• These fan headers are not configuration jumper blocks. Do not place a jumper cap on the
headers.
3/4/5) CPU_FAN/SYS_FAN1/SYS_FAN2/PWR_FAN (Fan Headers)
The motherboard has a 4-pin CPU fan header (CPU_FAN), a 3-pin (SYS_FAN1) and a 4-pin
(SYS_FAN2) system fan headers, and a 3-pin power fan header (PWR_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 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.

— 33 — BIOS Setup
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.)

item below to be configurable. Note: If your system fails to boot after overclocking, please wait for
20 seconds to allow for automated system reboot, or clear the CMOS values to reset the board to
default values. (Default: Disabled)
(Note) This item appears only if you install a CPU that supports this feature.
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.)
