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 dam-
age of the CPU may occur.
• Set the CPU host frequency in accordance with the CPU specifications. It is not recommended
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 frequency beyond the standard
specifications, please do so according to your hardware specifications including the CPU, graph-
ics card, memory, hard drive, etc.
1-3-1 Installing the CPU

B. Follow the steps below to correctly install the CPU into the motherboard CPU socket.
Before installing the CPU, make sure to turn off the computer and unplug the power cord from
the power outlet to prevent damage to the CPU.
Step 1:
Completely raise the CPU socket lever.
Step 3:
Remove the protective socket cover from the
load plate. (To protect the CPU socket, always
replace the protective socket cover when the
CPU is not installed.)
Step 5:
Once the CPU is properly inserted, replace the
load plate and push the CPU socket lever back
into its locked position.
Step 2:
Lift the metal load plate from the CPU socket.
(DO NOT touch socket contacts.)
Step 4:
Hold the CPU with your thumb and index fingers.
Align the CPU pin one marking (triangle) with the
pin one corner of the CPU socket (or you may
align the CPU notches with the socket alignment
keys) and gently insert the CPU into position.

1-3-2 Installing the CPU Cooler
Follow the steps below to correctly install the CPU cooler on the motherboard. (The following procedure uses
Intel®
boxed cooler as the example cooler.)
Step 1:
Apply an even and thin layer of thermal grease
on the surface of the installed CPU.
Male Push
Pin
Female
Push Pin
The Top
of Female
Push Pin
Direction of the
Arrow Sign on
the Male Push
Pin
Step 2:
Before installing the cooler, note the direction of
the arrow sign on the male push pin. (Turn-
ing the push pin along the direction of arrow is to
remove the cooler, on the contrary, is to install.)
Step 3:
Place the cooler atop the CPU, aligning the four
push pins through the pin holes on the mother-
board. 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 installation 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 moth-
erboard. If the push pin is inserted as the picture
above shows, the installation is complete.
Step 6:
Finally, attach the power connector of the CPU
cooler to the CPU fan header (CPU_FAN) on the
motherboard.

1-4-1 Dual Channel Memory Configuration
This motherboard provides four DDR2 memory sockets and supports Dual Channel Tech-
nology. After the memory is installed, the BIOS will automatically detect the specifications
and capacity of the memory. Enabling Dual Channel memory mode will double the original
memory bandwidth.
The four DDR2 memory sockets are divided into two channels and each channel has two memory sockets as
following:
Channel 0: DDR2_1, DDR2_2
Channel 1: DDR2_3, DDR2_4

Two Modules
Four Modules
Due to chipset limitations, 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.
3. Because of chipset limitations, to avoid the system being unable to start or the memory being incor-
rectly detected, if only one memory module is to be installed, we suggest that you install it on the
DDR2_1 or DDR2_3 socket; to install two memory modules, we suggest that you install them on the
DDR2_1 and DDR2_3 sockets. (Go to GIGABYTE’s website for the latest memory support list.)
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 direc-
tion. If you are unable to insert the memory, switch the direction.
When memory modules of different capacity and chips are installed, a message which says mem-
ory 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

— 31 — 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.»
Chapter 2 BIOS Setup
• 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 introductions 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 dam-
age 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 altering the settings may result in system’s
failure to boot. If this occurs, clear the CMOS values and reset the board to default values.)

This motherboard incorporates cable diagnostic feature designed to detect the status of the attached LAN
cable. This feature will detect cabling issue and report the approximate distance to the fault or short. Refer to
the following information for diagnosing your LAN cable:
When No LAN Cable Is Attached…
If no LAN cable is attached to the motherboard, the Status fields of all four pairs of wires will show Open
and the Length fields show 0m, as shown in the figure above.
When LAN Cable Is Functioning Normally…
If no cable problem is detected on the LAN cable connected to a Gigabit hub or a 10/100 Mbps hub, the
following message will appear:
Start detecting at Port…..
Link Detected —> 100Mbps
Cable Length= 30m
Link Detected Displays transmission speed.
Cable Length Displays the approximate length of the attached LAN cable.
Note: The Gigabit hub will only operate at a speed of 10/100 Mbps in MS-DOS mode; it will operate at a
normal speed of 10/100/1000 Mbps in Windows mode or when the LAN Boot ROM is activated.
