CPU
Supports Intel® Socket 478 Pentium® 4 (Willamette / Northwood) 1.4GHz~2.4GHz+ with 533MHz Front Side Bus (FSB) designed for Socket
478 technology.
Chipset
The motherboard is equipped with SIS 648 chipset. SIS 648 Host & Memory & AGP Controller integrates a high performance host interface
for Intel Pentium 4 processor, a high performance memory controller, a AGP interface. The SIS 648 Host Interface supports Intel Pentium
4 Series processors with FSB up to 133MHz. The host interface plays the role of processor transactions’ dispatcher. It dispatches
transactions to Memory, I/O interface and AGP bus. Transactions to different destinations can be dispatched concurrently in order to
maximum pipeline efficiency. The Memory controller can support DDR SDRAM. The memory controller also supports the Suspend to
RAM function by retaining the CKE# pins asserted in ACPI S3 state in which only AUX source deliver power. The AGP interface can
support external AGP slot with AGP 4X/8X capability and Fast Write Transactions.

Communication & Nectworking Riser (CNR)
Accelerated Graphics Port (AGP)
support data transfer rate up to 2112MB/s. Of six PCI slots provided, except the first PCI slot is slave, all other five slots are master PCI
slots with arbitration and decoding for all integrated functions and LPC bus.
specification provides a new level of video display sophistication and speed. The AGP video cards
slot provided from AX45-8X Max can support CNR interface for a Modem/Audio card. The
Memory
Provides three 184-pin DDR SDRAM DIMM sockets that support up to 2GB of PC2700(DDR333) and 3GB of PC2100(DDR266) compliant
SDRAM (Synchronous Dynamic Random Access Memory).
Watch Dog Timer
Includes AOpen “Watch Dog Timer” function that can auto-reset system in 4.8 seconds when you fail to system overclocking.
1MHz Stepping Frequency Adjustment
Provides “1MHz Stepping 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.

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.

You can clear CMOS to restore system default setting. To clear CMOS, follow the procedure below.
1. Turn off the system and unplug the AC power.
2. Remove ATX power cable from connector PWR2.
3. Locate JP14 and short pins 2-3 for a few seconds.
4. Return JP14 to its normal setting by shorting pin 1 & pin 2.
5. Connect ATX power cable back to connector PWR2.

This motherboard supports Intel® Pentium 4 Socket 478 series CPU (Willamette / Northwood). Be careful of CPU orientation when you plug
it into CPU socket.
1. Pull up the CPU socket lever and
up to 90-degree angle.
2. Locate Pin 1 in the socket and look for mark on the CPU upper interface.
Match Pin 1 and cut edge, then insert the CPU into the socket.
Note: Those pictures are for example only; they may not look the same with the motherboard you purchased.

This function is dedicated to overclockers and supports Adjustable CPU Core Voltage from 1.10V to 1.85V. However, this motherboard can
also automatically detects CPU VID signal and generates proper CPU core voltage.

BIOS Setup > Frequency/Voltage Control > CPU Clock Setting
This motherboard is CPU jumper-less design, you can set CPU frequency through the BIOS setup, and no jumpers or switches are needed.
The default setting is "table select mode". You can adjust the FSB from "CPU Speed Setting" for overclocking.
Core Frequency = CPU FSB Clock * CPU Ratio
PCI Clock = CPU FSB Clock / Clock Ratio
AGP Clock = PCI Clock x 2
