Abstract

A motherboard an electronic device using the same are provided. The motherboard includes a motherboard and a control chip. The processor is adapted to be inserted to a processor base including a plurality of pins. The pins is divided to defined pins and undefined pins. The processor base includes a plurality of electrical contacts. A first part of the electrical contacts are corresponding to the defined pins, and a second part of the electrical contacts are corresponding to the undefined pins. The control chip determines whether to make the motherboard enter an overclocking operation mode according to a control command. When the motherboard is set to be at the overclocking operation mode, the control chip transmits a control signal to the undefined pins of the processor via the second part of the electrical contacts, and then the processor improves operating efficiency.
