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!

WARNING!

Over heat Protect:

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.

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 processor and
motherboard overheat and damage, you may install an auxiliary cooling FAN, if
necessary.
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.

Only for Athlon XP serial CPU, when the CPU overheat, system will auto shut
down power supply. You can hear a continue beep sound, the power button will
be locked up. Users must turn off and turn on the AC power to reset the system
otherwise the power button will no function, the other way is keeping press the
push button few seconds till the beep sound stop, then release the power button
and press the power button again to turn on the power supply.

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 three 184-pin DUAL INLINE MEMORY MODULES (DIMM)
sites for memory expansion available from minimum memory size of 64MB to maximum
memory size of 3.0GB DDR SDRAM.

Valid Memory Configurations

Bank 184-Pin DIMM Total Memory

Bank 0, 1 (DDR1) DDR 266/333/400 DDR SDRAM X1 64MB∼1.0GB
Bank 2, 3 (DDR2) DDR 266/333/400 DDR SDRAM X1 64MB∼1.0GB
Bank 4, 5 (DDR3) DDR 266/333/400 DDR SDRAM X1 64MB∼1.0GB

Total System Memory (Max. 3.0GB) 3 64MB∼3.0GB

NOTE!

Make sure the total installed memory does not exceeds 3.0GB, 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

DDR 266/333/400

DDR2 (BANK2 + BANK3)

DDR1 (BANK0 + BANK1)

DDR3 (BANK4 + BANK5)

DDR SDRAM module looks like.

Figure 2-4

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.

10

WARNING!

For the DDR SDRAM CLOCK is set at 166MHz, use only DDR333 compliant
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!

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.

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.

2-5-2 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.
