1.6 Before 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.

ASUS P4G800-V motherboard user guide 1-9
1.7 Motherboard installation
Before you install the motherboard, study the configuration of your chassis to
ensure that the motherboard fits into it. The motherboard uses theATX form factor
that measures 12 inches x 9.6 inches (30.5 cm x 24.5 cm).
Do not overtighten the screws! Doing so may damage the motherboard.
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.
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.
Place this side towards
the rear of the chassis

1-10 Chapter 1: Product introduction
1.8 Central Processing Unit (CPU)
1.8.1 Overview
The motherboard comes with a surface mount 478-pin Zero Insertion Force (ZIF)
socket. The socket is designed for the Intel
®
Pentium
®
4 Processor in the 478-pin
package with 512KB L2 cache. This processor supports 800/533/400MHz front
side bus (FSB), and allows data transfer rates of up to 6.4GB/s. The socket will
also support the Intel Prescott CPU when available.
Note in the illustration that the CPU has a
