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

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.

What is Hyper-Threading?
Hyper-Threading technology is an innovative design from Intel that enables multi-threaded software applications to process threads in
parallel within each processor resulting in increased utilization of processor execution resources. As a result, an average improvement of
~40% in CPU resource utilization yields higher processing throughput.
How Hyper-Threading Works
A form of simultaneous multi-threading technology (SMT), Hyper-Threading technology allows multiple threads of software applications to
be run simultaneously on one processor by duplicating the architectural state on each processor while the same processor execution
resources is shared. The figure below
represents how a Hyper-Threading
based processor differentiates a
traditional multiprocessor. The left-hand
configuration shows a traditional
multiprocessor system with two physical
processors. Each processor has its own
independent execution resources and
architectural state. The right-hand
configuration represents an Intel
Hyper-Threading technology based
processor. You can see that the
architectural state for each processor is
duplicated, while the execution resources
is shared.
24
AAXX44GGEE TTuubbee--GG // AAXX44PPEE TTuubbee--GG OOnnlliinnee MMaannuuaal
For multiprocessor-capable software
applications, the Hyper-Threading
based processor is considered two
separate logical processors on which
the software applications can run
without modification. Also, each logical
processor responds to interrupts
independently. The first logical
processor can track one software
thread, while the second logical
processor tracks another software
thread simultaneously. Because the
two threads share the same execution
resources, the second thread can use
resources that would be otherwise idle
if only one thread was executing. This
results in an increased utilization of the
execution resources within each
physical processor.
The figure below represents how Hyper-Threading saves time when it works. With two logical processors available on every single physical
processor, multi-threaded applications can now take advantage of thread-level parallelism on each physical processor for additional
performance. As software applications continue to be optimized to take greater advantage of processor parallelism, Hyper-Threading
technology provides an additional boost for newer capabilities and the growing needs of today’s users.

Cool down CPU and Chipset are important for system reliability. Enlarged aluminum heat sink provides better heat consumption especially
when you are trying to over-clock the CPU.

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 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

Warning: Intel 845GE/PE chipset supports maximum
400MHz (100MHz*4) / 533MHz (133MHz*4) system bus
and 66MHz AGP clock; higher clock setting may cause
serious system damage.
Note: Since the latest processor, Northwood,
would detect the clock ratio automatically,
you may not be able to adjust the clock ratio
in BIOS manually.

This motherboard has three 184-pin DDR DIMM sockets that allow you to install PC1600 (DDR200), PC2100 (DDR266) or PC2700
(DDR333) memory up to 2GB. To have better and stable performance of the memory, we also provide several options of memory voltages
for you to choose. You can setup an appropriate voltage with a range between 2.50V and 2.70V in BIOS.
