IEEE 1394 (for AK79D-400 1394)
This motherboard comes with great function of IEEE1394 which provides transfer data rate up to 400Mbps.
1MHz Stepping CPU Frequency Adjustment
Provides “1MHz Stepping Frequency Adjustment” function in the BIOS. This magic function allows you to adjust CPU FSB
frequency from 100~200MHz by 1MHz stepping, and lets your system get maximum performance.
1MHz Stepping AGP/PCI Frequency Adjustment
AOpen provide sets of AGP/PCI frequencies for overclockers to manually overclock AGP/PCI frequency while taking care of the
system stability at the same time. Your adjustment on AGP/PCI would not affect the CPU clock speed at all, because the
working frequencies of AGP/PCI and CPU FSB are functioning asynchronously. With this solution given, there would be no
hassle from AGP/PCI overclocking, and thus PCI frequency would no longer be a headache to do overclocking anymore.
Power Management/Plug and Play
Supports the power management function that confirms to the power-saving standards of the U.S. Environmental Protection
Agency (EPA) Energy Star program. It also offers
making the system much more user-friendly.
Plug-and-Play, which helps saving users from configuration problems, thus

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 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 powered off when CPU
temperature reaches 97 degree, but it 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.

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.

FSB=133~200MHz by 1MHz Stepping CPU Overclocking
Warning: nForce2 Ultra 400 chipset supports 166MHz FSB (with performance
reaches maximum 400MHz EV6 system bus) and 66MHz AGP clock, higher clock
setting may cause serious system damage.
y
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 ABS” reset
the system after few seconds and system will auto-detect hardware again.

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.

In the past, we used to have 64-bit memory bandwidth for memory access. No matter how
many memory modules have been installed, though capacity added, the speed of access
remains the same. With 128-bit dual channel introduced, it doubles the memory bandwidth up to 5.4GB in advanced 128-bit
mode.
This motherboard supports DDR400/333/266 with Maximum capacity up to 3GB. This motherboard has three 184-pin
DIMM sockets
DDR RAM is supported, other type of modules will cause serious damage on memory sockets or SDRAM module. For over
clocking purpose, you can adjust memory voltage in BIOS from 2.5V to 2.65V.
that allow you to install 128-bit dual channel DDR400 or DDR333 or DDR266 memory up to 3GB. Only Non-ECC
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.

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.

AACC PPoowweerr AAuuttoo RReeccoovveerryy
A traditional ATX system should remain at power off stage when AC power resumes from power failure. This design is
inconvenient for a network server or workstation, without an UPS, that needs to keep power-on. This motherboard implements
an AC Power Auto Recovery function to solve this problem.
