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.
1-4-1 Dual Channel Memory Conguration
This motherboard provides four DDR2 memory sockets and supports Dual Channel Tech-
nology. After the memory is installed, the BIOS will automatically detect the specications
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:
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.
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 exibility to upgrade by allowing different memory sizes to be populated and remain in
Dual Channel mode/performance.

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 com-
ponents on the motherboard. Before connecting the power connector, rst 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.
• Use of a power supply providing a 2x4 12V power connector is recommended by the CPU
manufacturer when using an Intel Extreme Edition CPU (130W).
• 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.
The motherboard has a 4-pin CPU fan header (CPU_FAN), a 4-pin (SYS_FAN2) and a 3-pin (SYS_FAN1)
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.

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 conguration 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 conguration 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 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.
• 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.)

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 elds of all four pairs of wires will show Open
and the Length elds show 0m, as shown in the gure 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
- 51 -BIOS Setup
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

When a Cable Problem Occurs...
If a cable problem occurs on a specied pair of wires, the Status eld will show Short and then length
shown will be the approximate distance to the fault or short.
Example:
Explanation: A fault or short might occur at about 2m on Part 1-2.
Note: Part 4-5 and Part 7-8 are not used in a 10/100 Mbps environment, so their Status elds will show

4-1 Xpress Recovery2
Xpress Recovery2 is a utility that allows you to quickly compress and
back up your system data and perform restoration of it. Supporting NTFS,
FAT32, and FAT16 le systems, Xpress Recovery2 can back up data on
PATA and SATA hard drives and restore it.
Before You Begin:
• Xpress Recovery2 will check the rst physical hard drive* for the operating system. Xpress Recovery2 can
only back up/restore the rst physical hard drive that has the operating system installed.
• As Xpress Recovery2 will save the backup le at the end of the hard drive, make sure to leave enough un-
allocated space in advanced (10 GB or more is recommended; actual size requirements vary, depending
on the amount of data).
• It is recommended to back up your system soon after the operating system and drivers are installed.
• The amount of data and hard drive access speed may affect the speed at which the data is backed up/
restored.
• It takes longer to back up a hard drive than to restore it.
System Requirements:
• At least 512 MB of system memory
• VESA compatible graphics card
• Windows XP with SP1 or later, Windows Vista
• Xpress Recovery and Xpress Recovery2 are different utilities. For example, a backup le created
with Xpress Recovery cannot be restored using Xpress Recovery2.
• USB hard drives are not supported.
• Hard drives in RAID/AHCI mode are not supported.
Installation and Conguration:
Turn on your system to boot from the Windows Vista setup disk.
A. Installing Windows Vista and Partitioning the Hard Drive
Step 1:
Click Drive options.
"*" Xpress Recovery2 checks the rst physical hard drive in the following sequence: The rst PATA IDE connector, the second PATA IDE connector, the rst SATA connector, the second SATA connector and so forth. For example, when hard drives
are attached to the rst IDE and the rst SATA connectors, the hard drive on the rst IDE connector is the rst physical drive.
When hard drives are attached to the rst and second SATA connectors, the hard drive on the rst SATA connector is the rst
physical drive.
Step 2:

4-2 BIOS Update Utilities
GIGABYTE motherboards provide two unique BIOS update tools, Q-Flash™ and @BIOS™. GIGABYTE
Q-Flash and @BIOS are easy-to-use and allow you to update the BIOS without the need to enter MS-DOS
mode. Additionally, this motherboard features the DualBIOS™ design, which enhances protection for the
safety and stability of your computer by adding one more physical BIOS chip.
What is DualBIOS™?
Motherboards that support DualBIOS have two BIOS onboard, a main BIOS and
a backup BIOS. Normally, the system works on the main BIOS. However, if the
main BIOS is corrupted or damaged, the backup BIOS will take over on the next system boot and copy the
BIOS le to the main BIOS to ensure normal system operation. For the sake of system safety, users cannot
update the backup BIOS manually.
What is Q-Flash™?
With Q-Flash you can update the system BIOS without having to enter operating
systems like MS-DOS or Window rst. Embedded in the BIOS, the Q-Flash tool
frees you from the hassles of going through complicated BIOS ashing process.
What is @BIOS™?
@BIOS allows you to update the system BIOS while in the Windows environ-
ment. @BIOS will download the latest BIOS le from the nearest @BIOS server
site and update the BIOS.
4-2-1 Updating the BIOS with the Q-Flash Utility
A. Before You Begin
1. From GIGABYTE's website, download the latest compressed BIOS update le that matches your motherboard model.
2. Extract the le and save the new BIOS le (e.g. ep45ud3.f1) to your oppy disk, USB ash drive, or hard
drive. Note: The USB ash drive or hard drive must use FAT32/16/12 le system.
3. Restart the system. During the POST, press the <End> key to enter Q-Flash. Note: You can access
Q-Flash by either pressing the <End> key during the POST or pressing the <F8> key in BIOS Setup.
However, if the BIOS update le is saved to a hard drive in RAID/AHCI mode or a hard drive attached to
an independent IDE/SATA controller, use the <End> key during the POST to access Q-Flash.

unexpected failures when performing a BIOS update.
2. During the BIOS update process, ensure the Internet connection is stable and do NOT interrupt the
Internet connection (for example, avoid a power loss or switching off the Internet). Failure to do so may
result in a corrupted BIOS or a system that is unable to start.
3. Do not use the G.O.M. (GIGABYTE Online Management) function when using @BIOS.
4. GIGABYTE product warranty does not cover any BIOS damage or system failure resulting from an inad-
equate BIOS ashing.
