8.  Although this motherboard offers stepless control, it is not recommended 

to perform over-clocking. Frequencies other than the recommended CPU 

bus frequencies may cause instability of the system or damage the CPU.

9.  While CPU overheat is detected, the system will automatically shutdown.

Before you resume the system, please check if the CPU fan on the moth-

erboard functions properly and unplug the power cord, then plug it back 

again. To improve heat dissipation, remember to spray thermal grease 

between the CPU and the heatsink when you install the PC system.

10.  EuP stands for Energy Using Product, was a provision regulated by the 

European Union to de

fi

 ne the power consumption for the completed sys-

tem. According to EuP, the total AC power of the completed system

should be under 1.00W in off mode condition. To meet EuP standards, 

an EuP ready motherboard and an EuP ready power supply are required. 

According to Intel’s suggestion, the EuP ready power supply must meet 

the standard of 5v, and the standby power ef

fi

 ciency should be higher 

than 50% under 100 mA current consumption. For EuP ready power sup-

ply selection, we recommend you to check with the power supply manu-

facturer for more details.
