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 Smart Fan---( The Noise Management SystemOnly support 4-pin CPU cooler)

It’s never been a good idea to gain the performance of your system by sacrificing its acoustics.

CPU Smart Fan Noise Management System is the answer to control the noise level needed for

now-a-day’s high performance computing system. The system will automatically increase the

fan speed when CPU operating loading is high, after the CPU is in normal operating condition,

the system will low down the fan speed for the silent operating environment. The system can

provide the much longer life cycle for both CPU and the system fans for game use and

business requirements.

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.

(2) ATX 12V Power Connector (4-pin block) : ATX12V

This is a new defined 4-pins connector that usually comes with ATX Power Supply.

The ATX Power Supply which fully supports AM2 processor must including this

connector for support extra 12V voltage to maintain system power consumption.

Without this connector might cause system unstable because the power supply can not

provide sufficient current for system.
