CPU
Supports Intel® Socket 478 Pentium® 4 1.4GHz~2.8+GHz with 400/533MHz system bus designed for Socket 478 technology.
Chipset
The Intel® 850E chipset supports dual-channel RDRAM memory, delivering the most performance and headroom to maximize
the performance of Pentium 4 processor-based systems. Its Memory Control Hub (MCH) delivers dual RDRAM memory
channels and a 400/533 MHz system bus, providing the latest graphics support through 1.5V AGP4X technology. The enhanced
I/O Controller Hub (ICH2) delivers twice the I/O bandwidth over traditional bridge architecture and provides dedicated data paths
to fully optimize the additional bandwidth.
Expansion Slots
Including five 32-bit/33MHz PCI, one CNR and one AGP slots. The PCI local bus throughput can be up to 132MB/s. Of five PCI
slots provided, AX4T-533 Pro supports five master PCI slots for arbitration and decoding functions. The Communication &
Nectworking Riser (CNR) slot provided from AX4T-533 Pro supports CNR interface for a Modem/Audio card. The Accelerated
Graphics Port (AGP) specification provides a new level of video display sophistication and speed. The AGP video cards support
data transfer rate up to 1066MB/s. As AX4T-533 Pro motherboard includes one AGP expansion slot for a bus mastering AGP
graphic card, for AD and SBA signaling, AX4T-533 Pro can support AGP 4X mode.

Protection Agency (EPA) Energy Star program. It also offers Plug-and-Play
thus making system user-friendlier.
, which helps save users from configuration problems,
1MHz Stepping CPU Frequency Adjustment
Provides “1MHz Stepping CPU Frequency Adjustment” function in the BIOS. This magic function allows you to adjust CPU FSB
frequency from 100~248MHz by 1MHz stepping adjustment, and helps your system get maximum performance.
Hardware Monitoring Management
Supports CPU or system fans status, temperature and voltage monitoring and alert, through the on-board hardware monitor
module.
Enhanced ACPI
Fully implement the ACPI standard for Windows® 98/ME/2000/XP series compatibility, and supports Soft-Off, STR (Suspend to
RAM, S3), STD (Suspend to Disk, S4), WOM (Wake On Modem), WOL (Wake On LAN) features.
Super Multi-I/O

This chapter describes jumpers, connectors and hardware devices of this motherboard.
Note: Electrostatic discharge (ESD) can damage your processor, disk drives, expansion boards, and
other components. Always observe the following precautions before you install a system component.
1. Do not remove a component from its protective packaging until you are ready to install it.
2. Wear a wrist ground strap and attach it to a metal part of the system unit before handling a
component. If a wrist strap is not available, maintain contact with the system unit throughout any
procedure requiring ESD protection.

When you read this online manual and start to assemble your computer system, you may notice that some of the functions are
marked as “User Upgrade Optional” or “Manufacture Upgrade Optional”. Although all of AOpen’s motherboards have included
many amazing and powerful features, sometimes not every user is familiar with these powerful features. As a result of this we
define features that can be upgraded by users as “User Upgrade Optional”. You can upgrade these functions by purchasing
additional devices. As for functions that cannot be upgraded by users, we define them as “Manufacture Upgrade Optional”. If
need be, you can contact our local distributors or resellers to purchase “Manufacture Upgrade Optional” components, and again
you are also welcome to visit our official website at www.aopen.com
for detail information.

This motherboard supports Intel® Pentium® 4 1.4~2.4GHz Socket 478 series CPU. Please follow steps below to finish CPU
installation. Be careful of CPU orientation when you plug it into CPU socket.
1. Pull up the CPU socket level and
up to 90-degree angle.
2. Locate Pin 1 in the socket and look for a black dot or cut
edge on the CPU upper interface. Match Pin 1 and cut edge,
then insert the CPU into the socket.
Note: These pictures are for example only; they may not look exactly the same as the motherboard you purchased.

Note: This socket supports
Micro-FC-PGA2 package CPU, which
is the latest CPU package developed
by Intel. Other forms of CPU package
cannot be fitted in.
Note: If you do not match the CPU
socket Pin 1 and CPU cut edge well, it
may damage the CPU.
Note: P4 CPU tends to produce higher
temperature; for better heat dissipation,
we recommend you to install this
motherboard with a bigger housing.
Besides, by doing so you can prevent
components from colliding.
