A method capable of detecting a status of a basic input/output system (BIOS) for setting a clock is applied to a clock generating device of a computer motherboard and sets the clock according to a signal status of the BIOS or a trigger signal. A device capable of detecting the BIOS status for setting the clock is also proposed. The device has a crystal oscillator, a frequency control unit, a phase-lock-loop (PLL) spread-spectrum unit electrically connected with the crystal oscillator and the frequency control unit, a memory unit having a clock setting value stored therein, a detection control unit electrically connected with the memory unit and used to detect a signal status, and a logic control unit electrically connected with the PLL spread-spectrum unit, the frequency control unit and the detection control unit.
