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.

This motherboard provides a surface mount, Zero Insertion Force (ZIF) CPU socket,
referred to as the mPGA940 socket supports AMD 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
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.

Appendix I
Power Supply Mold and FAN Solution
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

15
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 recommended 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

Appendix II
Thunder Protection Feature
Introduction:
Thunder is such formidable natural force that it can render massive damage to electronic
products of all kinds. In thunderstorm season computer systems without powerful thunder
protection designs are vulnerable to electric surge damage. High-priced building with
thunder protection measures may be a good choice, but usually costly and with corners
uncovered. The best solution for both cybercafés owner and common users would be
Jetway Thunder Series motherboards.
Thunder Protection Technology from Jetway Thunder Series Motherboard
Jetway Thunder series motherboards are integrated with double thunder-protection walls,
one from network port and the other from LAN chip. When it thunders, the first
thunder-protection wall will analyze and recognize thunder surge in network cable and
transfer it to ground wire area. The second thunder-protection wall will protect against any
residual electric current or runaway electrons to ensure safety of network card and other
components of the motherboard.
Laboratory test statistics on IEC61000-4-5 (1.2-50us) standardized thunder electric surge
tests have verified that Jetway Thunder series motherboard can endure up to 9KV electric
surge and protect the system from possible thunder damage.
IEC61000-4-5 (1.2-50us) Standardized Thunder Electric Surge Laboratory Test
Medium rise time: T1=1.2us±30%, T2=50us±30%
Test1: Current Partial Discharge tests on Jetway Thunder Series Motherboards with double
Thunder-protection Walls.
Test Result: Each MB can endure up to 9KV voltage of electric surge. Some motherboards
will restart (mostly depends on LAN chip), but no damage occurs to motherboards or
components of the board. System works normally after a restart.
Test2: Current Partial Discharge tests on Motherboards without Thunder-protection function
Test Result: LAN chips are damaged when testing voltage reached to 5KV. System fails to
operate normally (in most cases systems can not access to network) after a restart.

17
Conclusion: Jetway’s Thunder Series motherboard can guard motherboard from thunder
electric surge damage with effect and ensure system security from as high as 9KV volts of
electric surge.
Bonus of Thunder-protection Motherboard
Jetway Thunder series motherboards adopt dual thunder protection walls to cover every
corner in network loops. Such a complete thunder protection provided to users, especially
cybercafés means less repair cost and more effective business time. Jetway Thunder series
can guard system stability with effect. With Jetway Thunder series motherboards, together
with reasonable disposal of electric wires, proper placing of electric devices, piped network
cables and other necessary thunder protection devices, your computer system will be intact
in thunderstorm weather.
