Abstract: An efficiency optimization method for hardware devices with adjustable clock frequencies is provided. The work current of the hardware device is measured and used to obtain the corresponding work level from a conversion table. The obtained work level is compared with the currently executing work level to make adjustments for various parameters for the hardware device and for the operation of the corresponding heat-dissipating device. Therefore, the hardware device can achieve a better performance.

Abstract: A method for increasing an operating rate of a graphics card includes: raising a rotation rate of a radiator fan of a graphics processing unit chip of the graphics card to a first rotation rate according to a rate increasing command; raising a voltage inputted to the graphics processing unit chip to a first voltage, and raising a voltage inputted to a memory of the graphics card to a second voltage when the rotation rate of the radiator fan is approximately equal to the first rotation rate; and raising a timing of the graphics processing unit chip to a first timing, and raising a timing of the memory to a second timing when the voltage inputted to the graphics processing unit chip is approximately equal to the first voltage, the voltage inputted to the memory being approximately equal to the second voltage.
