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 I nterface 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 both DDR and SDR. 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 2X/4X/8X capability and Fast Write Transactions.

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 incl uded 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 o r
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 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. Locat e 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.

Then, BIOS will detect the CPU’s default frequency and POST again. With this special feature, you can easily overclock your system to get
a higher system performance without removing the system housing and save the hassle from setting the jumper to clear CMOS data when
system hangs.

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.
You can adjust the FSB from "CPU Host/SDRAM/PCI Clock" for overclocking.
Core Frequency = CPU FSB Clock * CPU Ratio
PCI Clock = CPU FSB Clock / Clock Ratio
AGP Clock = PCI Clock x 2
