a 478-pin surface mount ZIF socket. The Pentium 4 processor with 512KB L2
cache on 0.13 micron process features the Intel
architecture that includes hyper-pipelined technology , a rapid execution
engine, a 533MHz system bus, and an execution trace cache to offer a
significant increase in performance. See page 2-4 for more information.
®
Pentium® 4 Processor via
®
NetBurst™ micro-
DDR memory support
Employing the Double Data Rate (DDR) memory technology, the P4B533
motherboard supports up to 2GB of system memory using PC2100/1600
DDR DIMMs. The ultra-fast 266MHz memory bus doubles the speed of the
PC133 SDRAM to deliver the required bandwidth for the latest 3D
graphics, multimedia, and Internet applications. See page 2-10.
USB 2.0 technology
The motherboard implements the new Universal Serial Bus (USB) 2.0
specification, extending the connection speed from 12 Mbps on USB 1.1
to a fast 480 Mbps on USB 2.0. The higher bandwidth of USB 2.0 allows
connection of devices such as high resolution video conferencing
cameras, next generation scanners and printers, and fast storage units.
USB 2.0 is backward compatible with USB 1.1. See page 2-29.
NOTICE: The Microsoft USB 2.0 driver has not been officially released
as of the support CD production date. Please download the USB 2.0
driver from the Microsoft website (www.microsoft.com) to upgrade your
USB 1.1 ports to USB 2.0.
Digital audio interface
On audio models, a digital audio connector is onboard to accommodate
the bundled Sony/Philips Digital Interface (S/PDIF) In/Out module, which
supports coaxial interfaces. Experience 5.1-channel surround sound and
enhanced 3D audio while playing DVDs and computer games. See page
2-32.
1-2
Chapter 1: Product introduction
ASUS EZ Plug™
This patented ASUS technology lets you use your existing power supply
rather than buying a new ATX 12V power supply. The ASUS EZ Plug™ is
a 4-pin auxillary +12V connector mounted on the motherboard that
connects a regular 4-pin device power connector from the power supply.
This connector is necessary to provide the additional power required by
the P4 CPU. See page 2-27.
ASUS POST Reporter™
P4B533 offers a new exciting feature called the ASUS POST Reporter™
to provide friendly voice messages and alerts during the Power-On SelfTests (POST). Through the system’s internal speaker, or an added
external speaker, you will hear the messages informing you of the system
boot status and causes of boot errors, if any. The bundled Winbond Voice
Editor software allows you to customize the voice messages, and provides
multi-language support. See details on pages 4-25 and 5-20.
ASUS MyLogo2™
This new feature present in the P4B533 motherboard allows you to
personalize and add style to your system with customizable boot logos.
See details on pages 4-35 and 5-10.
ASUS Multi-language BIOS
The multi-language BIOS allows you to select the language of your choice
from the available options. The localized BIOS menus allow you to
configure easier and faster. Visit the ASUS website for information on the
supported languages. See page 4-11 on how to select your desired
language.
ASUS P4B533 motherboard user guide
1-3
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 floppy disk.
ASUS Q-Fan feature
The ASUS Q-Fan technology smartly adjusts the fan speeds according to
the system loading to ensure quiet, cool, and efficient operation. See
details on page 4-32.
1.3.2 Value-added solutions
Overclocking
The P4B533 overclocking features:
• adjustable CPU frequency multiple in BIOS using the ASUS
JumperFree™ solution
• adjustable FSB/DDR/AGP frequency ratio
• adjustable CPU V
• Stepless Frequency Selection (SFS) for fine-tuning system bus
frequency from 100MHz up to 200MHz at 1MHz increments
, and DDR memory and AGP voltages
CORE
Concurrent PCI
This feature allows multiple PCI transfers from PCI master buses to the
memory and processor.
Temperature, fan, and voltage monitoring
The CPU temperature is monitored by the ASUS ASIC to prevent
overheating and damage. The system fan rotations per minute (RPM) is
monitored for timely failure detection. The system voltage levels are
monitored to ensure stable supply of current for critical components.
1-4
Chapter 1: Product introduction
Dual function power switch
While the system is ON, pressing the power switch for less than 4 seconds
puts the system to sleep mode or to soft-off mode, depending on the BIOS
setting. Pressing the power switch for more than 4 seconds lets the
system enter the soft-off mode regardless of the BIOS setting.
ACPI ready
The Advanced Configuration power Interface (ACPI) provides more energy
saving features for operating systems that support OS Direct Power
Management (OSPM).
Auto fan off
The system fans power off automatically when the system is in sleep
mode. This feature reduces both power consumption and system noise.
Chassis intrusion detection
The motherboard supports chassis intrusion monitoring through the ASUS
ASIC. A chassis intrusion event is retained in the system memory for more
protection.

high-performance floppy disk controller for a 360K/720K/1.44M/
2.88M floppy disk drive, a multi-mode parallel port, two standard
compatible UARTs, a Standard Infrared (SIR), and a Flash ROM
interface.
AGP warning LED. Serving as a smart burn-out protection for the
motherboard, this red LED lights up if you plug in any 3.3V AGP
card into the AGP slot. When this LED is lit, there is no way you
can turn on the system power even if you press the power button.
AGP slot. This Accelerated Graphics Port (AGP) slot supports 1.5V
AGP4X mode graphics cards for 3D graphical applications.

ASUS P4B533 motherboard
2.1 Motherboard installation
Before you install the motherboard, study the configuration of your chassis
to ensure that the motherboard fits into it. The P4B533 uses the ATX form
factor that measures 12 inches x 8.6 inches (30.5 x 21.9 cm), a standard
fit for most 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.
2.1.1 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.
2.1.2 Screw holes
Place six (6) 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

2.3 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.
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 before removing or plugging in any motherboard
component.
The red LED (AGP_WARN) is a smart protection from motherboard
burn out caused by an incorrect AGP card. If you plug in any 3.3V AGP
card into the 1.5V AGP slot, this LED lights up thus preventing the
system to power up. This LED remains off if you plug in a 1.5V AGP
card.

2.4 Central Processing Unit (CPU)
2.4.1 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 on 0.13 micron
process. This processor includes the Intel® NetBurst™ micro-architecture
that features the hyper-pipelined technology, rapid execution engine,
533/400MHz system bus, and execution trace cache. Together, these
attributes improve system performance by allowing higher core
frequencies, faster execution of integer instructions, and data transfer
rates of 4.2GB/s and 3.2GB/s.
Gold Mark
Note in the illustration that the CPU has a gold triangular mark on one
corner. This mark indicates the processor Pin 1 that should match a
specific corner of the CPU socket.
Incorrect installation of the CPU into the socket may bend the pins and
severely damage the CPU!
