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.

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.
23
ll
AAXX4455FF--11339944 OOnnlliinnee MMaannuua
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.

The Over Current Protection is a popular implementation on ATX 3.3V/5V/12V switching power supply. However, the new generation CPU
uses different voltage with a regulator to transfer 12V to CPU voltage (for example, 2.0V), and thus makes 5V over current protection
useless. This motherboard is with switching regulator onboard supporting CPU over-current protection; in conjunction with 3.3V/5V/12V
power supply provide the full line over-current protection.
ATX Switching Power Supply
Note: Although we have implemented protection circuit try to prevent any human operating mistake,
there is still certain risk that CPU, memory, HDD, add-on cards installed on this motherboard may be
damaged because of component failure, human operating error or unknown nature reason. AOpen
cannot guaranty the protection circuit will always work perfectly.

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.

BIOS Setup > Frequency/Voltage Control > CPU Bus Frequency
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 Bus Frequency" for overclocking.
Core Frequency = CPU FSB Clock * CPU Ratio
PCI Clock = CPU FSB Clock / Clock Ratio
AGP Clock = PCI Clock x 2
CPU Ratio 8x, ……….30x
CPU FSB (By BIOS table) 100~248MHz by 1MHz stepping
