Product
introduction
This chapter describes the motherboard
features and the new technologies
it supports.

1-2 Chapter 1: Product introduction
1.3 Special features
1.3.1 Product highlights
Latest processor technology
The motherboard comes with a 775-pin surface mount Land Grid Array
(LGA) socket designed for the Intel® Pentium® 4 processor in the 775-land
package. The motherboard supports the Intel® Pentium 4, Intel® Pentium D,
Intel® Celeron and Intel® Dual-Core processors featuring 800/533 MHz Front
Side Bus (FSB), dedicated L2 cache, and a core speed of up to 3.8GHz.
The motherboard also supports the Intel Hyper-Threading Technology,
the Intel® Extended Memory 64 Technology (EM64T) that allows 64-bit
computing, and the Enhanced Intel Speedstep® Technology (EIST) that
intelligently adjusts the CPU voltage and frequency depending on the CPU
loading, system speed or power requirement. See page1-9 for details.

ASUS P5P800-VM 1-3
Intel®65nanometer process technology support
The motherboard supports Intel®processors built on the 65-nanometer
(nm) process technology with copper interconnect. Intelʼs 65 nm process is
the most advanced chip manufacturing technology, delivering breakthrough
performance, enhanced media experience, and low power consumption.
The Intel® 65 nm Dual-Core processors utilize this package technology for
a thinner, lighter design without compromising performance. See page 1-9
for details.
Integrated Intel®Extreme Graphics 2
The Intel®865G chipset on the motherboard integrates the Intel®Extreme
Graphics 2 architecture to deliver realistic 3D/2D graphics with sharp
images, fast rendering, smooth motion, and clearly dened details. This unique
architecture balances the memory usage between graphics and the system
for optimal performance with a maximum UMA share memory size of 96MB, a
maximum resolution of 2048 x 1536(@75Hz) and a maximum refresh rate
of 85Hz(@1800 x 1440). See page 1-27 for details.
Dual-channel DDR400 memory support
Employing the Double Data Rate (DDR) memory technology,
the motherboard supports up to 4GB of system memory using
DDR400/333/266 DIMMs. The ultra-fast 400MHz memory bus delivers the
required bandwidth for the latest 3D graphics, multimedia, and Internet
applications. See 1-16 to 1-19 for details.
Serial ATA technology
The motherboard supports the Serial ATA technology through the Serial
ATA interfaces and the Intel® ICH5 chipset. The SATA specication allows
for thinner, more exible cables with lower pin count, reduced voltage
requirement, and up to 150 MB/s data transfer rate. See page 1-29 for details.
AI Audio
The motherboard comes with the Realtek®ALC655 audio CODEC that lets
you enjoy high-quality 6-channel audio without having to buy advanced
sound cards. It also features intelligent detection of plugged peripherals into the
audio ports and identies any incompatible devices. See page 1‑27 for details.

1-4 Chapter 1: Product introduction
1.3.2 Innovative ASUS features
CPU Lock Free Support
This feature allows you to adjust the CPU multiplier to 14X. Making
appropriate BIOS setting automatically reduces the CPU multiplier value for
more exibility when increasing external FSB.
CrashFree BIOS 2
This feature allows you to restore the original BIOS data from the support
CD in case when the BIOS codes and data are corrupted. This protection
eliminates the need to buy a replacement ROM chip. See details on page 2-6.
ASUS EZ Flash BIOS
With the ASUS EZ Flash, you can easily update the system BIOS even
before loading the operating system. No need to use a DOS-based utility or
boot from a oppy disk. See page 2‑3 for details.
10/100 Mbps LAN support
Easy connectivity to your network or broadband connection with the
onboard LAN port. Allows you to play online games without buying
expensive additional LAN cards. See page 1-26 for details.
AGP 8X support
The AGP 8X (AGP 3.0) VGA interface specication enhances graphics
performance with high bandwidth speeds up to 2.12 GB/s.
USB 2.0 technology
The motherboard implements the Universal Serial Bus (USB) 2.0
specication, 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 page 1-27 and page 1-32 for
details.
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 xure detection. The ASIC
monitors the voltage levels to ensure stable supply of current for critical
components. See page 2-28 for details.

ASUS P5P800-VM 1-5
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. See page 1-23 for details.

1-6 Chapter 1: Product introduction
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
to 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.

1.5 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.
1.5.1 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.
1.5.2 Screw holes
Place eight (8) screws into the holes indicated by circles to secure the
motherboard to the chassis.
Place this side towards
the rear of the chassis
