Environmental Safety Instruction
z Avoid the dusty, humidity and temperature extremes. Do not place the product in any
area where it may become wet.
z 0 to 40 centigrade is the suitable temperature. (Actual figure depends on the request of
the main chipset)
z Generally 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.
z The 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.
z Attention to the heat sink when you over-clocking. The higher temperature may
decrease the life of the device and burned the capacitor.

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.
CPU VID--- Shift to Higher Performance
The CPU voltage can be adjusted for the precisely over-clocking of extra demanding
computing performance.
CPU Vcore Input & Output OC-CON (High-polymer Solid Electrolysis Aluminum
Capacitors)
CPU Vcore Input and Output adopt OC-CON solid capacitors. OC-CON solid
capacitors make it possible for motherboard to work from 55 degrees Centigrade
below zero to 125 degrees centigrade. OC-CON capacitors possess superior physical
characteristics to prolong product life ten times than corresponding motherboard
without capacitors every time working temperature increases 20 degrees. Life of
product of motherboard with solid capacitors declines only 10% of those without solid
capacitors as well under same conditions.

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
17
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

Subject 3: 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
Thunder Series motherboards.
Thunder Protection Technology from Thunder Series Motherboard
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 Thunder series motherboard can endure up to 9KV electric s urge
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 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.
Conclusion:
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.
