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.

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.
Note: Although we have implemented protection circuit and tried to prevent any human operating
mistake, certain risks might still happen when CPU, memory, HDD or add-on cards installed on this
motherboard is damaged due to component failure, human operating error or other unknown natural
reasons. AOpen cannot guarantee that the protection circuit will always work perfectly.

BIOS Setup > Frequency/Voltage Control > CPU Clock Setting
This motherboard is CPU jumper-less design, you can set CPU frequency in BIOS; 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

This motherboard has two 184-pin DDR DIMM sockets that allow you to install 128-bit dual channel DDR400, DDR333 or DDR266 memory
up to 2GB. Only non-ECC DDR RAM is supported. Please install suitable modules; otherwise serious damage may occur on memory
sockets or you RAM modules. Please note that when you install DDR333 memory module and have your CPU FSB set at 800MHz,
the memory can only run with the speed of DDR320. It is limitation of Intel. For other limitation of CPU types, please see the table
below.
Warning: This motherboard supports DDR RAM. Please do
not install the SDRAM on the DDR RAM sockets; otherwise it
will cause serious damage on memory sockets or SDRAM
module.

Note: To run dual channel speed, you have to use
the same type memory modules installed on two
DIMMs. If you install two different sized modules,
the system can only run single channel mode and
with the speed of that lower memory module.

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.
