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.

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 Vcore 7-Shift---Shift to Higher Performance

The CPU voltage can be adjusted up by 7 steps for the precisely over-clocking of

extra demanding computing performance.

referred to as the LGA775 socket supports Intel Pentium Dual Core processor in the

775 Pin package utilizes Flip-Chip Land Grid Array (FC-LGA) 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! 1.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.

. Suggest the power of CPU should below 65w.

To install a CPU, first turn off your system and remove its cover. Locate the LGA775

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.
