Safety information

Electrical safety

To prevent electrical shock hazard, disconnect the power cable from the electrical outlet before relocating the system.

When adding or removing devices to or from the system, ensure that the power cables for the devices are unplugged before the signal cables are connected. If possible, disconnect all power cables from the existing system before you add a device.

Before connecting or removing signal cables from the motherboard, ensure that all power cables are unplugged.

Seek professional assistance before using an adpater 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.

Operation safety

Before installing the motherboard and adding devices on it, carefully read all the manuals that came with the package.

Before using the product, make sure all cables are correctly connected and the power cables are not damaged. If you detect any damage, contact your dealer immediately.

To avoid short circuits, keep paper clips, screws, and staples away from connectors, slots, sockets and circuitry.

Avoid dust, humidity, and temperature extremes. Do not place the product in any area where it may become wet.

Place the product on a stable surface.

If you encounter technical problems with the product, contact a qualified service technician or your retailer.

1.4Special features

1.4.1 Product highlights

333MHz FSB Athlon XP CPU support

AMD’s Athlon XP 2800+ and all follow-up CPUs now support 333MHz Front Side Bus (FSB) for increased application program productivity and enhanced digital media experience.

AGP 8X support

AGP 8X (AGP 3.0) is the next generation VGA interface specification that enables enhanced graphics performance with high bandwidth speeds up to 2.12 GB/s. With a bus of 533Mhz, AGP 8X is twice as fast as AGP 4X.

DDR400 (PC3200) support

DDR400 (PC3200), the latest and fastest DDR memory standard, supports bandwidth up to 3.2 GB/s to provide enhanced system performance.

(Note: PC2700 maximum to 4 banks only. PC3200 maximum to 2 banks only.)

C.O.P. (CPU Overheating Protection):

With AMD® Athlon XPinstalled, the motherboard offers automatic CPU Overheating Protection to prolong the life of the entire system. If the CPU temperature exceeds the set criteria, the PC shuts down automatically.

ASUS EZ Flash

With ASUS EZ Flash, you can update BIOS before entering operating system. No more DOS-based flash utility and bootable diskette required.

SoundMax Digital Audio System (on audio models only)

The SoundMax Digital Audio System is the industry’s highest performance and most reliable audio solution for business professionals, audiophiles, musicians, and gamers. SoundMAX Digital Audio System can output 5.1 channel surround and features state-of-the-art DLS2 MIDI synthesizer with Yamaha DLSbyXG sound set, 5.1 Virtual Theater™ and supports all major game audio technologies

including Microsoft DirectX™8.0, Microsoft DirectSound 3D™, A3D, MacroFX, ZoomFX, MultiDrive 5.1 and EAX. Refer to section “3.2.5 Multi-channel audio feature” on page 3-5 for more information.

C.P.R. (CPU Parameter Recall)

When the system hangs due to overclocking failure, there is no need to open the case to clear the CMOS data. Simply restart the system and the BIOS will automatically restore the CPU default setting for each parameter.

CrashFree BIOS

CrashFree BIOS allows users to restore BIOS data from a floppy diskette even when BIOS code and data are corrupted during upgrade or invaded by a virus. Unlike other competing vendors’ products, ASUS motherboards now enable users to enjoy this protection feature without the need to pay for an optional ROM.

1.6Before you proceed

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

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

2.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.

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

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

5.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.

When lit, the green LED (SB_PWR) indicates that the system is ON, in sleep mode, or in soft-off mode, a reminder that you should shut down the system and unplug the power cable before removing or plugging in any motherboard component.

1.7Motherboard installation

Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits into it. The motherboard uses the ATX form factor that measures 12 inches x 9.6 inches (30.5 cm x 24.5 cm).

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

1.7.1 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.

1.7.2 Screw holes

Place nine (9) screws into the holes indicated by circles to secure the motherboard to the chassis.

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

Place this side towards the rear of the chassis

1.8Central Processing Unit (CPU)

The motherboard provides a Socket A (462) for CPU installation. AMD processors offer gigahertz speeds to support all the latest computing platforms and applications. The A7V8X-X supports AthlonTM XP, AthlonTM, Barton™ and Duron TM processors.

1.8.1Installing the CPU

Follow these steps to install a CPU:

1.Locate the Socket 462 and open it by pulling the lever gently sideways away from the socket. Then lift the lever upwards. The socket lever must be fully opened (90 to 100 degrees).

2.Insert the CPU with the correct orientation. The notched or golden corner of the CPU must be oriented toward the inner corner of the socket base nearest to the lever hinge.

The CPU should drop easily into place. Do not force the CPU into the socket to avoid bending the pins. If the CPU does not fit, check its alignment and look for bent pins.

4.Once completely inserted, press the CPU firmly and close the socket lever until it snaps shut.

5.Place the CPU fan and heatsink on the CPU. The heatsink should entirely cover the CPU. Carefully attach the heatsink locking brace to the plastic clips on the socket base. With the added weight of the CPU fan and heatsink locking brace, no extra force is required to keep the CPU in place
