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 feature s 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

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.

This motherboard comes with a retention module attached on the CPU socket when shipped, we strongly recommend you to install
AOpen special designed CPU Fan as shown below on the retention module for better heat dissipation. Please install the CPU Fan
correctly as the following pictures shown.
1. Gently put the CPU Fan down on the
retention module with clips aligning correctly
to the four corners.
Note: The picture above may look different from the product you purchased.
2. Pressing down the four clips with force one by one
on the retention module.

CPU VID signal and SMbus clock generator provide CPU voltage auto-detection and allows the user to set the CPU frequency through
the BIOS setup, therefore no jumpers or switches are used. The disadvantages of the Pentium based jumper-less designs are
eliminated. There will be no worry of wrong CPU voltage detection.

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, 1.475V), 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.

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/RAM/PCI Clock" 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, 10x… 25x, 26x, 27x, 28x
CPU FSB (By BIOS table) 100-255MHz
