AMD Athlon™ / Duron™ Processor Family
Cooling Solutions
As processor technology pushes to faster speeds and higher performance, thermal management
becomes increasingly crucial when building computer systems. Maintaining the proper thermal
environment is key to reliable, long-term system operation. The overall goal in providing the proper
thermal environment is keeping the processor below its specified maximum case temperature.
Heatsinks induce improved processor heat dissipation through increased surface area and
concentrated airflow from attached fans. In addition, interface materials allow effective transfers of
heat from the processor to the heatsink. For optimum heat transfer, AMD recommends the use of
thermal grease and mounting clips to attach the heatsink to the processor.
When selecting a thermal solution for your system, please refer to the website below for collection of
heatsinks evaluated and recommended by AMD for use with AMD processors. Note, those heatsinks
are recommended for maintaining the specified Maximum T case requirement. In addition, this
collection is not intended to be a comprehensive listing of all heatsinks that support AMD processors.

2-3-2 About AMD Athlon & Duron 462-pin CPU
This motherboard supports Socket-A (Socket-462) AMD Athlon/Duron processors.
This motherboard Provides a ZIF Socket-A. The CPU that comes with the motherboard
should have a cooling FAN attached to prevent overheating. If this is not the case, then
purchase a correct cooling FAN before you turn on your system.
WARNING!
Be sure that there is sufficient air circulation across the processor’s heatsink
and CPU cooling FAN is working correctly, otherwise it may cause the
9
processor and motherboard overheat and damage, you may install an auxiliary
cooling FAN, if necessary.
WARNING!
Due to this motherboard provides new function of protecting CPU；you must
connect the CPU FAN connector on FAN1 location in order to obtain this
feature. Without connection on FAN1 (or you have connect CPU FAN on
FAN2), the system will shut down immediately to protect both your CPU and
motherboard.
To install a CPU, first turn off your system and remove its cover. Locate the ZIF socket and
open it by first pulling the level sideways away from the socket then upward to a 90-degree
angle. Insert the CPU with the correct orientation as shown below. The notched corner
should point toward the end of the level. Because the CPU has a corner pin for two of the
four corners, the CPU will only fit in the orientation as shown.
CPU ZIF Socket-A
Colden Arrow
Socket-A
AMD
When you put the CPU into the ZIF socket. No force require to insert of the CPU, then press
the level to Locate position slightly without any extra force.
2-4 Install Memory
This motherboard provides two 184-pin DUAL INLINE MEMORY MODULES (DIMM)
sites for memory expansion available from minimum memory size of 64MB to maximum
memory size of 2.0GB DDR SDRAM.
Valid Memory Configurations
Bank 184-Pin DIMM Total Memory
Bank 0, 1 (DDR1) DDR200/DDR266 DDR SDRAM X1 64MB∼1.0GB
Bank 2, 3 (DDR2) DDR200/DDR266 DDR SDRAM X1 64MB∼1.0GB
Total System Memory (Max. 2.0GB) 2 64MB∼2.0GB
NOTE!
Make sure the total installed memory does not exceeds 2.0GB, otherwise the
system may hang during startup.
Generally, installing DDR SDRAM modules to your motherboard is very easy, you can refer
to figure 2-4 to see what a 184-Pin DDR200/DDR266 DDR SDRAM module looks like.
10
DDR2 (BANK2 + BANK3)
DDR1 (BANK0 + BANK1)
NOTE!
When you install DIMM module fully into the DIMM socket the eject tab
should be locked into the DIMM module very firmly and fit into its
indention on both sides.
WARNING!
For the DDR SDRAM CLOCK is set at 133MHz, use only DDR266compliant DDR Modules. When this motherboard operate at 133MHz, most
system will not even boot if non-compliant modules are used because of the
strict timing issues, if your DDR Modules are not DDR266-compliant, set
the DDR SDRAM clock to 100MHz to ensure system stability.
2-5 Expansion Cards
WARNING!
Turn off your power when adding or removing expansion cards or other
system components. Failure to do so may cause severe damage to both
your motherboard and expansion cards.
2-5-1 Procedure For Expansion Card Installation
1. Read the documentation for your expansion card and make any necessary hardware or
software setting for your expansion card such as jumpers.
2. Remove your computer’s cover and the bracket plate on the slot you intend to use.
3. Align the card’s connectors and press firmly.
4. Secure the card on the slot with the screen you remove above.
5. Replace the computer system’s cover.
6. Set up the BIOS if necessary.
7. Install the necessary software driver for your expansion card.
2-5-2 Assigning IRQs For Expansion Card
Some expansion cards need an IRQ to operate. Generally, an IRQ must exclusively assign to
one use. In a standard design, there are 16 IRQs available but most of them are already in use.
Standard Interrupt Assignments
IRQ Priority Standard function
0 N/A System Timer
1 N/A Keyboard Controller

11 * 2 IRQ Holder for PCI Steering
12 * 4 PS/2 Compatible Mouse Port
13 N/A Numeric Data Processor
14 * 5 Primary IDE Channel
15 * 1 Secondary IDE Channel
* These IRQs are usually available for ISA or PCI devices.
2-5-3 Interrupt Request Table For This Motherboard

IMPORTANT! If using PCI cards on shared slots, make sure that the drivers support
“Shared IRQ” or that the cards don’t need IRQ assignments. Conflicts will
arise between the two PCI groups that will make the system unstable or
cards inoperable.

ATX Power Supply connector. This is a new defined 20-pins connector that usually
comes with ATX case. The ATX Power Supply allows to use soft power on momentary
switch that connect from the front panel switch to 2-pins Power On jumper pole on the
motherboard. When the power switch on the back of the ATX power supply turned on,
the full power will not come into the system board until the front panel switch is
momentarily pressed. Press this switch again will turn off the power to the system
board.
