Patent ID: 8274271

Claim:
A motherboard with an overvolting function, the motherboard comprising: a specified component receiving an operating voltage; a voltage regulator for generating the operating voltage according to a reference voltage; and a micro-controller, which is embedded on the motherboard and is directly connected to the voltage regulator, receiving a voltage increasing signal or a voltage decreasing signal from outside the motherboard and adjusting a voltage value of the reference voltage according to the voltage increasing signal or the voltage decreasing signal; an external input device, directly connected to the micro-controller, outputting the voltage increasing signal or the voltage decreasing signal to the micro-controller, wherein the micro-controller adjusts the voltage value of the reference voltage according to the voltage increasing signal or the voltage decreasing signal only when the motherboard is being turned on or being turned off or in a sleep mode; a standby power source, directly connected to the micro-controller, providing power to the motherboard when the motherboard is being turned on or being turned off or in the sleep mode.
