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
procedures requiring ESD protection.

When you read this online manual and start to assemble your computer system, you may find some of functions are called “Manufacturer
Upgrade Optional”, and some are called “User Upgrade Optional”. Though all AOpen motherboards include many amazing and powerful
features, in some situations, these powerful features are not used to every user. Hence, we changed some key features as “Manufacturer
Upgrade Optional” for you to choose. Some optional functions that can be upgraded by users, we call them “User Upgrade Optional”. As for
those optional functions that can’t be upgraded by ourselves, we call them “Manufacturer Upgrade Optional”. If needed, you can contact our
local distributors or resellers for purchasing “User Upgrade Optional” components, and again you can visit AOpen official web site:

This motherboard supports AMD Athlon XP, Athlon and Duron Socket 462 series CPU. Be careful of CPU orientation when you plug it into
CPU socket (with CPU Overheat Protection function implemented, the system will be automatically power off when the temperature of
CPU reached 97 degree, but works on AthlonXP CPU only).
1. Pull up the CPU socket lever and
up to 90-degree angle.
2. Locate Pin 1 in the socket and look for a black dot or cut edge on the CPU
upper interface. Match Pin 1 and cut edge, then insert the CPU into the
socket.

Breaking through traditional outlook of motherboard, AOpen now brings you a new fresh look of motherboard! – EzColor!
Fancy? You may think so, but actually it is a practical and useful feature for amateur or even power-users. Coming in specific color for
specific connector and module, components on motherboard are now born with their respective colors. Users may now easily recognize
what jumper or cable should match with specific jumper or cable by COLOR, without having the trouble of holding user guide in one hand
and connecting jumpers with the other hand.
And what makes this feature so great is that, even the easy-to-get-confused front panel connector is differentiated now with different light
colors!

With AMD platform substantially keeps increasing the speed of its CPU, it inevitably led to the
annoying problem of high CPU operation temperature at the same time. In order to prevent
accidental failure of CPU fan, which could cause the burning down of the AthlonXP CPU, we, AOpen, have meticulously
developed a new technology, named, O.H.P. (Overheat Protection) Technology to protect them. Thanks to the intelligent
monitoring design of AOpen O.H.P. technology, user can now finally set their mind at ease even when fan failed to work without
fearing the possible damage of CPU.
Under the circumstances that CPU fan is running properly,
AthlonXP temperature should be way below the highest
temperature limit of 97℃. However, if CPU fan accidentally
becomes malfunction or improperly installed, the CPU
temperature would rocket abruptly, and you may find your
system hang up or crying over the smoking CPU if you haven’t
installed AOpen O.H.P. previously. With AOpen O.H.P.
technology applied, the specific thermal detection pins on
AthlonXP CPU would sense voltage difference when processor
is overheated with fan failed, and the overheat protection
system would immediately send out a signal to abort your
system by cutting CPU electricity before any damage is done.
Unlike other manufacturers who use BIOS or software to
control the power supply of CPU, AOpen O.H.P. Technology is
purely hardware-controlled the minute after system boot-up,
and occupies no system resource. We are pleasant to phase in
this practical function on all AOpen AMD series motherboards to protect customer’s valuable hardware and personal data.

Over Current Protection has been popularly implemented on ATX 3.3V/5V/12V switching power supply for a while. However,
new generation CPU is able to use regulator of different voltages to transfer 12V to CPU voltage (for example, to 2.0V). This
motherboard is with switching regulator onboard that supports CPU over-current protection, and it applies to 3.3V/5V/12V power
supply for providing full line over-current protection.

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.

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

This function is dedicated to overclockers. The CPU core voltage of this motherboard is adjustable 1.10V to 1.85V by 0.05V
stepping. But this motherboard can also automatically detect CPU VID signal and generates proper CPU core voltage.
BIOS Setup > Frequency/Voltage Control > CPU Voltage Setting
Warning: Higher CPU core voltage may be
able to increase CPU speed for overclocking,
but you may damage the CPU or reduce the
CPU lifecycle.

to restore the default setting when changing a new
CPU, because the system will still implement the

Tip: If your system hangs or fails to boot because of
overclocking, simply use <Home> key to restore the
default setting or you can wait the AOpen “Watch Dog

will auto-detect hardware again.
