Safety Environmental Instruction
zAvoid the dusty, humidity and temperature extremes. Do not place the product in
any area where it may become wet.
z0 to 40 centigrade is the suitable temperature. (The figure comes from the request
of the main chipset)
zGenerally speaking, dramatic changes in temperature may lead to contact
malfunction and crackles due to constant thermal expansion and contraction from
the welding spots’ that connect components and PCB. Computer should go
through an adaptive phase before it boots when it is moved from a cold
environment to a warmer one to avoid condensation phenomenon. These water
drops attached on PCB or the surface of the components can bring about
phenomena as minor as computer instability resulted from corrosion and oxidation
from components and PCB or as major as short circuit that can burn the
components. Suggest starting the computer until the temperature goes up.
zThe increasing temperature of the capacitor may decrease the life of computer.
Using the close case may decrease the life of other device because the higher
temperature in the inner of the case.
zAttention to the heat sink when you over-clocking. The higher temperature may
decrease the life of the device and burned the capacitor.

AMD AM3 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 AM3 processors by AMD. In addition, this collection is not intended to be a
comprehensive listing of all heatsinks that support AM3 processors.

1-1.1 Special Features of Motherboard
CPU Thermal Throttling Technology---(The CPU Overheat Protection Technology)
To prevent the increasing heat from damage of CPU or accidental shutdown while at high
workload, the CPU Thermal Throttling Technology will force CPU to enter partially idle mode from
87.5% to 12.5% according to preset CPU operating temperature in BIOS (from 40℃to 90℃).
When the system senses the CPU operating temperature reaching the preset value, the CPU
operating bandwidth will be decreased to the preset idle percentage to cool down the processor.
When at throttling mode the beeper sound can be optionally selected to indicate it is in working.

2-3-2 About AMD AM3 CPU Installation
This motherboard provides a socket AM3 surface mount, Zero Insertion Force (ZIF)
socket, referred to as the mPGA940 socket supports AMD AM3 series processors.
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.

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
3 * 8 Communications Port (COM2)
4 * 9 Communications Port (COM1)
5 * 6 Sound Card (sometimes LPT2)
6 * 11 Floppy Disk Controller
7 * 7 Printer Port (LPT1)
8 N/A System CMOS/Real Time Clock
9 * 10 ACPI Mode when enabled

2-6-1 Connectors
(1) Power Connector (24-pin block): ATXPWR1
ATX Power Supply connector: This is a new defined 24-pins connector that
usually comes with ATX case. The ATX Power Supply allows using 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.
