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.

2-3-1 Glossary
Chipset (or core logic) - two or more integrated circuits which cont rol th e int erfaces between
the system processor, RAM, I/O devises, and adapter cards.
Processor slot/socket - the slot or socket used to mount the system processor on the
motherboard.
Slot (AGP, PCI, ISA, RAM) - the slots used to mount adapter cards and system RAM.
AGP - Accelerated Graphics Port - a high speed interface for video cards; runs at 1X
(66MHz), 2X (133MHz), or 4X (266MHz).
PCI - Peripheral Component Interconnect - a high speed interface for video cards, sound
cards, network interface cards, and modems; runs at 33MHz.
ISA - Industry Standard Architecture - a relatively low speed interface primarily used for
sound cards and modems; runs at approx. 8MHz.
Serial Port - a low speed interface typically used for mouse and external modems.
Parallel Port - a low speed interface typically used for printers.
PS/2 - a low speed interface used for mouse and keyboards.
USB - Universal Serial Bus - a medium speed interface typically used for mouse, keyboards,
scanners, scanners, and some digital cameras.
Sound (interface) - the interface between the sound card or integrated sound connectors and
speakers, MIC, game controllers, and MIDI sound devices.
LAN (interface) - Local Area Network - the interface to your local area network.
9
BIOS (Basic Input/Output System) - the program logic used to boot up a computer and
establish the relationship between the various components.
Driver - software, which defines the characteri stics of a device for use by another device or
other software.
Processor - the "central processing unit" (CPU); the principal integrated circuit used for doing
the "computing" in "personal computer"
Front Side Bus Frequency -
the working frequency of the motherboard, which is generated
by the clock generator for CPU, DRAM and PCI BUS.
CPU L2 Cache -
the flash memory inside the CPU, normally Athlon CPU has 256K or above,
while Duron will have 64K.
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!
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.

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)
And two 168-pin SDRAM Module Socket sites for memory expansion available from
minimum memory size of 64MB to maximum memory size of 2.0GB DDR SDRAM.
Users only can install either 168-pin SDRAM Module or 184-pin DDR DRAM Module at
one time.

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 PC2100-compliant
DDR Modules or PC133 compliant SDRAM Modules. When this
motherboard operate at 133Mhz, most system will not even boot if noncompliant modules are used because of the strict timing issues, if your
DRAM Modules are not PC133/PC2100-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 N/A System Timer
1 N/A Keyboard Controller
2 N/A Programmable Interrupt

IMPORTANT!
If using PCI cards on shared slots, make sure that the drivers support
“S hared 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.
