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.

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.
