1.3.3 ASUS Intelligent Performance and Overclocking
features

Super Memspeed Technology

To attain top performance, ASUS has managed to break through current FSB

and DRAM ratio proportions by utilizing Super Memspeed Technology- the latest

technology that provides even more precise overclocking options to unleash

the true potential of DDR3 memory. Native DDR3 1333 maximizes system

performance by eliminating the bottleneck when overclocking both the CPU and
the memory- providing great performance for 3D graphics and other memory
demanding applications. Refer to page 2-13 for details.

AI NOS™ (Non-Delay Overclocking System)

The patented ASUS Non-delay Overclocking System™ (AI NOS™) technology
auto-detects the CPU loading and dynamically overclocks the CPU speed when
needed. Unlike other dynamic overclocking techniques, AI NOS™ reacts much
faster to satisfy your need for speed. See page 4-16 and 5-22 for details.

AI Booster

The ASUS AI Booster allows you to overclock the CPU speed in Windows
environment without the hassle of booting the BIOS.

Precision Tweaker

This feature allows you to ne tune the CPU/memory voltage and gradually
increase the memory Front Side Bus (FSB) and PCI Express frequency at 1MHz

increment to achieve maximum system performance.

C.P.R. (CPU Parameter Recall)

The C.P.R. feature of the motherboard BIOS allows automatic re-setting to the
BIOS default settings in case the system hangs due to overclocking. When the
system hangs due to overclocking, C.P.R. eliminates the need to open the system
chassis and clear the RTC data. Simply shut down and reboot the system, and the
BIOS automatically restores the CPU default setting for each parameter.

2.6 Jumper

1. Clear RTC RAM (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. Remove the onboard battery.

3. 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.

4. Reinstall the battery.

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

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

• You do not n e e d to clear the RTC when th e syst e m hangs due to
overclocking. For system failure due to overclocking, use the C.P.R. (CPU

4.2 BIOS setup program

This motherboard supports a programmable Serial Peripheral Interface (SPI) chip
that you can update using the provided utility described in section 4.1 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 of the

SPI chip.

The SPI 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 Setup Defaults item under the
Exit Menu. See section 4.8 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.
