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.

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.
22
AAXX4455HH--88XX MMaaxx OOnnlliinnee MMaannuuaall
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.

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

Plug in the CPU fan cable to the 3-pin CPUFAN1 connector. If you have chassis fan, you can also plug it on SYSFAN2 or SYSFAN3
connector.

This motherboard has three 184-pin DDR DIMM sockets that allow you to install PC2100 (DDR266) memory up to 3GB or PC2700
(DDR333) memory up to 2GB. Please note that when you install PC1600 or PC2100 DDR SDRAM, you can install them fully into 3 sockets;
however, when you install PC2700 DDR SDRAM, we suggest you to install DIMM1 and DIMM2 ONLY.

Please follow the procedure as shown below to finish memory installation.
1. Make sure the DIMM module’s pin face down and match the socket’s size as depicted below.
2. Insert the module straight down to the DIMM slot with both hands and press down firmly until the DIMM module is securely in place.
3. Repeat step 2 to finish additional DIMM modules installation.

Note: The tabs of the DIMM slot
will close-up to hold the DIMM in
place when the DIMM touches the
slot’s bottom.

DDR SDRAM utilizes the existing SDRAM infrastructure and technology while doubling the nominal bandwidth available to systems. To put
it in a simple way, DDR SDRAM is like data going along a two lane highway, while at the same time data in traditional SDRAM go along a
one way street. Therefore, it is a more advanced technology that provides a great overall improvement in system performance. DDR266
(PC2100) runs two times faster than the traditional PC133 SDRAM with the speed of Front Side Bus (FSB) up to 266MHz. (2x133=266).
And DDR333 (PC2700) is running at 333MHz FSB. Both PC2100 and PC2700 are a new naming standard for speed of DDR 266 and
DDR 333, representing their theoretical speeds of the RAM. The theoretical transfer rate of DDR 266 (PC2100) is 2.1GB/s and 2.7GB/s is
for DDR 333 (PC2700).
