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 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 CPUFAN (FAN1)
location in order to obtain this feature. Without connection on
CPUFAN (or you have connect CPU FAN on SYSFAN), 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.

When you put the CPU into the ZIF socket. No forces require to insert of the CPU,
then press the level to Locate position slightly without any extra force.
2-3-3 Over clock Running
WARNING! This section is for experienced motherboard installer only. Over
clocking can result in system instability or even shortening life of
the processor.
After setting the Jumper JK1 you can choose over clock running by BIOS CMOS
SETUP UTILITY. When you entered CMOS SETUP UTILITY, choose “Miscellaneous
Control” you will see the screen as below, when setting clock control by software,
you can setting Host Clock step by step in Host Clock at next boot from 100MHz to
166MHz for user approach over clock running.

2-4 Install Memory
This motherboard provides two 168-pin DUAL INLINE MEMORY MODULES
(DIMM) sites for memory expansion available from minimum memory size of 16MB
to maximum memory size of 1GB SDRAM.
Valid Memory Configurations
Bank 168-Pin DIMM Total Memory
Bank 0, 1
(DIMM1) SDRAM 32, 64, 128, 256, 512MB X 1 16MB∼512MB

(DIMM2) SDRAM 32, 64, 128, 256, 512MB X 1 16MB∼512MB
Total System Memory (Max. 1GB) 16MB∼1GB
Generally, installing SDRAM modules to your motherboard is very easy, you can
refer to figure 2-4 to see what a 168-pin PC100 & PC133 SDRAM module looks like.
DIMM2 (BANK2+ BANK3) DIMM1 (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 SDRAM CLOCK is set at 133MHz, use only PC133-compliant
DIMMs. 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 DIMM are not PC133-compliant, set the 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 1 System Timer
1 2 Keyboard Controller
2 N/A Programmable Interrupt
3 * 11 Communications Port (COM2)
4 * 12 Communications Port (COM1)
5 * 13 Sound Card (sometimes LPT2)
6 14 Floppy Disk Controller
7 * 15 Printer Port (LPT1)

9 * 4 ACPI Mode when enabled
10 * 5 IRQ Holder for PCI Steering
11 * 6 IRQ Holder for PCI Steering
12 * 7 PS/2 Compatible Mouse Port
13 8 Numeric Data Processor
14 * 9 Primary IDE Channel
15 * 10 Secondary IDE Channel
* These IRQs are usually available for ISA or PCI devices.
2-5-3 Interrupt Request Table For This Motherboard

14
Interrupt request are shared as shown the table below:
INT A INT B INT C INT D
PCI slot 1 ⎯Shared ⎯⎯
PCI slot 2 ⎯⎯Shared ⎯
PCI slot 3 ⎯⎯⎯Shared
Onboard VGA ⎯⎯⎯⎯
AC97/MC97 ⎯Shared ⎯⎯
Onboard USB1 ⎯⎯⎯Shared
Onboard USB 2 ⎯⎯⎯Shared
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.
2-6 Connectors, Headers
1. Power Connector: AT Power Connector (12-pin block): AT
This connector connects to a standard AT power supply. To connect the leads from
the power supply, ensure first that the power supply is not plugged. Most power
supplies provide two plugs (P8 and P9), each containing six wires, two of which
are black. Orient the connectors so that the black wires are located in the middle.
Using a slight angle, align the plastic guide pins on the lead to their receptacles on
the connector. Once aligned, press the lead onto the connector until the lead locks
into place.

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.
