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.

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

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.
Note: AOpen Overhear Protection Technology only support processors
base on 0.13-micron technology in this motherboard.

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.
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 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 Bus Frequency" for overclocking.
Core Frequency = CPU HTUBusUTH Clock * C PU Rat io
PCI Clock = CPU Bus Clock / Clock Ratio

Tip: If your system hangs or fails to boot because of overclocking, simply use

DDIIMMMM SSoocckkeettss
This motherboard has three 184-pin DDR HDIMMH sockets that allow you to install HUDDR266UHU/UHU 333UH U/400U memory up to 3 GB.
Non-ECC DDR RAM is supported. Otherwise, it will cause serious damage on memory sockets or RAM module.
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 RAM module.
Note: According to the standard DDR400 specification from
JEDEC (Joint Electron Device Engineering Council), it is
regulated that DDR400 supports only 2x DIMM on the memory
module for a maximum 2GB capacity, and DDR333 supports
up to 3x DIMM for a maximum of 3GB capacity. Please be
noted that KT600 series motherboards follow this standard
specification on memory as well.

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.

The ATX power supply uses 20-pin connector shown below. Make sure you plug in the right direction.
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.
