AMD K8 Processor Family
Cooling Solutions
As processor technology pushes to faster speeds and higher performance with increasing operation
clock, thermal management becomes increasingly crucial while building computer systems. Maintaining
the proper computing environment without thermal increasing is the key to reliable, stable, and 24
hours system operation. The overall goal is keeping the processor below its specified maximum case
temperature. Heatsinks induce improved processor heat dissipation through increasing surface area
and concentrated airflow from attached active cooling 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.
Please refer to the website below for collection of heatsinks evaluated and recommended for Socket-A
processors by AMD. In addition, this collection is not intended to be a comprehensive listing of all
heatsinks that support Socket-754 processors.

2-3-2 About AMD Athlon64 754-pin CPU
This motherboard provides a 754-pin surface mount, Zero Insertion Force (ZIF) socket,
referred to as the mPGA754 socket supports AMD Athlon64 processor in the 754 Pin package
utilizes Flip-Chip Pin Grid Array package technology.
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.
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 mPGAB Socket
Colden Arrow
Socket 754
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 DDR DUAL INLINE MEMORY MODULES
(DIMM) sites for DDR memory expansion available from minimum memory size of 64MB to
maximum memory size of 2.0GB DDR SDRAM.
Valid Memory Configurations
Bank 184-pin DDR DIMM PCS Total Memory
Bank 0, 1 (DIMM1) DDR266/DDR333/DDR400 DDR DRAM

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 SDRAM module looks like.
DIMM1 (BANK0+BANK1)
DIMM2 (BANK2+BANK3)
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 200MHz, use only DDR400- compliant
DDR Modules. When this motherboard operate at 200Mhz , most system will
not even boot if non-compliant modules are used because of the strict
timing issues, if your DDR Modules are not DDR400-compliant, set the
SDRAM clock to 133MHz 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

2-6 Connectors, Headers
2-6-1 Connectors
(1) Power Connector (20-pin block/ 24-pin block for REV:1.0 P.C.B) : ATXPWR
ATX Power Supply connector. This is a new defined 24-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.
** We recommend that you use an ATX 12V Specification 2.0-compliant power supply unit
(PSU) with a minimum of 350W power rating. This type has 24-pin and 4-pin power plugs.
** If you intend to use a PSU with 20-pin and 4-pin power plugs, make sure that the 20-pin
power plug can provide at least 15A on +12V and the power supply unit has a minimum
power rating of 350W. The system may become unstable or may not boot up if the power is
inadequate.
(2) ATX 12V Power Connector (4-pin block) : ATX12V
This is a new defined 4-pins connector that usually comes with ATX Power Supply. The
ATX Power Supply which fully support Pentium 4 processor must including this connector
for support extra 12V voltage to maintain system power consumption. Without this
connector might cause system unstable because the power supply can not provide sufficient
current for system.
(3) PS/2 Mouse & PS/2 Keyboard Connector: PS2KBMS
The connectors for PS/2 keyboard and PS/2 Mouse.
(4) USB Port connector: USB
The connectors are 4-pin connector that connect USB devices to the system board.
