1.3.4 ASUS Intelligent Overclocking features

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 5-21 for details.

PEG Link Mode

This feature enhances your PCI Express graphics card performance. It allows the
motherboard to automatically adjust the PCI Express graphics link mode to the

correct frequency based on the system conguration. Four additional settings are

available for overclocking the PEG Link Mode. See page 4-22 for details.

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. See page 4-16 to 4-18 for
details.

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.

Due to the chipset behavior, AC power off is required before using C.P.R.
function.

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.

2.1 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
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.

2.2 Motherboard overview

Before you install the motherboard, study the conguration of your chassis to
ensure that the motherboard ts into it.

Make sure to unplug the power cord before installing or removing the
motherboard. Failure to do so can cause you physical injury and damage
motherboard components.

Do not overtighten the screws! Doing so can damage the motherboard.

2.2.1 Placement direction

When installing the motherboard, make sure that you place it into the chassis in the
correct orientation. The edge with external ports goes to the rear part of the chassis
as indicated in the image below.

2.2.2 Screw holes

Place six (6) screws into the holes indicated by circles to secure the motherboard
to the chassis.

Place this side towards
the rear of the chassis
