•

Before connecting or removing signal cables from the motherboard,

ensure that all power cables are unplugged.

•

Seek professional assistance before using an adapter or extension cord.

These devices could interrupt the grounding circuit.

•

Make sure that your power supply is set to the correct voltage in your

area. If you are not sure about the voltage of the electrical outlet you are

using, contact your local power company.

•

If the power supply is broken, do not try to fix it by yourself. Contact a

qualified service technician or your retailer.

AI NET2

The AI NET2 is a BIOS-based diagnostic tool that detects and reports

Ethernet cable faults and shorts. With this utility, you can easily monitor

the condition of the Ethernet cable(s) connected to the LAN (RJ-45)

port(s). During the bootup process, AI NET2 immediately diagnoses the

LAN cable(s) and reports shorts and faults up to 100 meters at 1 meter

accuracy.

ASUS Hyper Path 2 technology ASUS Hyper Path 2 technology

memory performance without affecting system stability. See page 2-25 for

details.

USB 2.0 technology USB 2.0 technology

USB 2.0 technology

The motherboard implements the Universal Serial Bus (USB) 2.0

specification, dramatically increasing the connection speed from the

12 Mbps bandwidth on USB 1.1 to a fast 480 Mbps on USB 2.0. USB 2.0 is

backward compatible with USB 1.1. See pages 1-25 and 1-30 for details.

Temperature, fan, and voltage monitoringTemperature, fan, and voltage monitoring

Temperature, fan, and voltage monitoring

The CPU temperature is monitored by the ASIC (integrated in the Winbond

Super I/O) to prevent overheating and damage. The system fan rotations

per minute (RPM) is monitored for timely failure detection. The ASIC

monitors the voltage levels to ensure stable supply of current for critical

components. See page 2-32 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.

Onboard LEDOnboard LED

Onboard LED

The motherboard comes with a standby power LED that 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.

1.4 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, ensureBefore you install or remove any component, ensure

Before you install or remove any component, ensure

that the ATX power supply is switched off or thethat the ATX power supply is switched off or the
