Environmental Safety 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.

Hardware Installation
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.
2-1 CPU Installation
The motherboard provides a socket AM2 surface mount, Zero Insertion Force (ZIF)
socket, referred to as the mPGA940 socket supports AMD AM2/AM2/AM3
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
heat sink 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.

Appendix I
Subject 1: Regarding the Application of 3-Phase or 3+1 Phase
Power Supply Mold
As a result of the increasing power consumption demand from
many AMD CPUs in current market, we suggest not to use a CPU
that demands more than 65W power consumption at work for an
AMD CPU compliant board that comes with power supply design
as 3 phase or 3+1 phase mold and MOSFET design as working in
High SideX1 and Low SideX1 mold so as to avoid MOSFET getting
burned or other phenomena like a halted system or system
instability. So please take notice of the CPU you are using and make sure that it is one
that demand not more than 65 W to ensure long-term working order.
Note：
1. The relation between CPU Power Consumption Amount and Power Phase:
depending on difference in voltage rating, one-phase of power can provide
25~30W to the motherboard.
2. 3- Phase Power Supply Mold: motherboard with 3 inductances for CPU power
supply, and each inductance carries with it 2 MOSFET (6 MOSFETs in total)
(Figure1); 3+1–Phase Power Supply Mold: motherboard with 4 inductances for
CPU power supply, and each inductance carries with it 2 MOSFET (8 MOSFETs
in total) (Figure2).
Figure 1
Figure 2

Solution：
We recommend users choose motherboards with power design of 4-phase, 4+1
phase or more for CPUs that demand 89W or 95W power consumption.
We recommend users choose motherboards with power design of 5-phase, 5+1
phase or more for CPUs that demand 125W or 140W power consumption.
Subject 2: Suggestion on choosing electric fan
Both the amount of electric current to MOSFET and the heat
produced from the motherboard go up as AMD’s CPU power
consumption increases. In this case we recommend users select a
CPU fan with air outlet towards MOSFET so that CPU fan can carry
away heat produced by MOSFET, for better heat dissipation effects.
At the same time we suggest using well-ventilated cases to maintain temperature as
38 approximately inside℃. (38 is re℃commended by CPU manufactures)
Figure 1---- CPU Fan can not blow off the heat produced by MOSFET. We suggest
not to using fans of this kind.
Figure 2---- CPU Fan can blow off the heat produced by MOSFET. We suggest using
fans of this kind.
