1-4 Chapter 1: Product Introduction

ASUS Quiet Thermal Solution

ASUS Quiet Thermal solution makes system more stable and enhances the
overclocking capability.

ASUS Stack Cool 2

Stack Cool 2 is a fan-less and zero-noise cooling solution offered exclusively

by ASUS. It effectively transfers heat generated by the critical components
to the other side of the specially designed PCB (printed circuit board) for
effective heat dissipation.

Fanless Design - Heat-pipe

The Heat Pipe design effectively directs the heat generated by the chipsets to
the heatsink near the back IO ports, where it can be carried away by existing

airow from CPU fan or bundled optional fan. The purpose of the innovative

heat pipe design on this motherboard is that the groundbreaking fanless
design does not have lifetime problems as a chipset fan does. Furthermore, it

provides options for users to install side-ow fan or passive cooler. The Heat

Pipe design is the most reliable fanless thermal solution to date.

DO NOT uninstall the heat-pipe by yourself. Doing so may bend the tubing and
affect the heat dissipation performance.

Q-Fan 2

ASUS Q-Fan2 technology intelligently adjusts both CPU fan and chassis

2.1 Before you proceed

Take note of the following precautions before you install motherboard components
or change any motherboard settings.

• Unplug the power cord from the wall socket before touching any
component.

• Use a grounded wrist strap or touch a safely grounded object or to a metal
object, such as the power supply case, before handling components to
avoid damaging them due to static electricity.

• Hold components by the edges to avoid touching the ICs on them.

• Whenever you uninstall any component, place it on a grounded antistatic
pad or in the bag that came with the component.

• Before you install or remove any component, ensure that the ATX power
supply is switched off or the power cord is detached from the power
supply. Failure to do so may cause severe damage to the motherboard,
peripherals, and/or components.

Onboard LED

The motherboard comes with a standby power LED. The green LED lights up
to indicate that the system is ON, in sleep mode, or in soft-off mode. This is a
reminder that you should shut down the system and unplug the power cable before
removing or plugging in any motherboard component. The illustration below shows
the location of the onboard LED.

2.5.1 Installing an expansion card

To install an expansion card:

1. Before installing the expansion card, read the documentation that came with
it and make the necessary hardware settings for the card.

2. Remove the system unit cover (if your motherboard is already installed in a
chassis).

3. Remove the bracket opposite the slot that you intend to use. Keep the screw
for later use.

4. Align the card connector with the slot and press rmly until the card is

completely seated on the slot.

5. Secure the card to the chassis with the screw you removed earlier.

6. Replace the system cover.

2.5.2 Conguring an expansion card

After installing the expansion card, congure the it by adjusting the software

settings.

2.6 Jumpers

1. Clear RTC RAM (3-pin CLRTC)

This jumper allows you to clear the Real Time Clock (RTC) RAM in
CMOS. You can clear the CMOS memory of date, time, and system setup
parameters by erasing the CMOS RTC RAM data. The onboard button
cell battery powers the RAM data in CMOS, which include system setup
information such as system passwords.

To erase the RTC RAM

1. Turn OFF the computer and unplug the power cord.

2. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on
pins 2-3 for about 5–10 seconds, then move the cap back to pins 1-2.

3. Plug the power cord and turn ON the computer.

4. Hold down the <Del> key during the boot process and enter BIOS setup
to re-enter data.

Except when clearing the RTC RAM, never remove the cap on CLRTC jumper

default position. Removing the cap will cause system boot failure!

• If the steps above do not help, remove the onboard battery and move
the jumper again to clear the CMOS RTC RAM data. After the CMOS
clearance, reinstall the battery.

• You do not need to clear the RTC when the system hangs due to
overclocking. For system failure due to overclocking, use the C.P.R. (CPU
Parameter Recall) feature. Shut down and reboot the system so the BIOS
can automatically reset parameter settings to default values.

• Due to the chipset limitation, AC power off is required prior using C.P.R.
function. You must turn off and on the power supply or unplug and plug the
power cord before reboot the system.

3.2 BIOS setup program

This motherboard supports a programmable rmware chip that you can update

using the provided utility described in section 3.1 Managing and updating your
BIOS.

Use the BIOS Setup program when you are installing a motherboard, reconguring
your system, or prompted to “Run Setup.” This section explains how to congure

your system using this utility.

Even if you are not prompted to use the Setup program, you can change the

conguration of your computer in the future. For example, you can enable the

security password feature or change the power management settings. This

requires you to recongure your system using the BIOS Setup program so that the
computer can recognize these changes and record them in the CMOS RAM.

The rmware chip on the motherboard stores the Setup utility. When you start up

the computer, the system provides you with the opportunity to run this program.

Press <Del> during the Power-On Self-Test (POST) to enter the Setup utility;

otherwise, POST continues with its test routines.

If you wish to enter Setup after POST, restart the system by pressing
<Ctrl+Alt+Delete>, or by pressing the reset button on the system chassis. You can
also restart by turning the system off and then back on. Do this last option only if

the rst two failed.

The Setup program is designed to make it as easy to use as possible. Being a
menu-driven program, it lets you scroll through the various sub-menus and make
your selections from the available options using the navigation keys.

• The default BIOS settings for this motherboard apply for most conditions
to ensure optimum performance. If the system becomes unstable after
changing any BIOS settings, load the default settings to ensure system
compatibility and stability. Select the Load Default Settings item under the
Exit Menu. See section 3.8 Exit Menu.

• The BIOS setup screens shown in this section are for reference purposes
only, and may not exactly match what you see on your screen.

• Visit the ASUS website (www.asus.com) to download the latest BIOS le for

this motherboard.
