According to embodiments of the invention, temperature, current, or other physical quantities associated with an integrated circuit, which can also include a processor, may be converted to a digital signal, and that digital signal used to choose a corresponding frequency offset that is added to any pre-established overclocking frequency. Embodiments of the invention allow a user to specify a dynamic range between which the frequency offset is bounded during overclocking of the integrated circuit. The programmable lower limit specifies the frequency where the integrated circuit begins to overclock. The programmable upper limit specifies the maximum overclocking frequency that is allowed. Setting the lower limit to be equal to the upper limit forces overclocking to occur at only the specified value.

A computer system and overclock controlling method and program thereof, which includes steps of providing an overclock work voltage to a CPU when overclock is requested, then the CPU adjusts its clock domain according to the overclock work voltage. The overclock work voltage is a sum of a normal work voltage and an additional external voltage, by which the CPU may enter an overclock mode (a frequency of a clock domain signal is higher than a standard frequency value). Eventually, when the frequency of the clock domain signal of the CPU is in a stable status during the overclock mode, the work voltage for the CPU is reduced and the CPU keeps working in the overclock mode.

The invention relates to a computer mainboard with automatic adjusting hardware parameter value, so as to achieve the overclocking or energy-saving purposes by the automatic adjusting hardware parameter value and timely carry out overclocking or energy-saving operation, after system halted is carried out, the computer can be automatically restarted by the mainboard, and then the overclocking or energy-saving operation is carried out continuously. A watchdog unit is connected with a frequency generator, after a presetting period, the frequency generator is informed and a re-start signal is generated. The frequency generator can automatically decrease or increase the present generated frequency progressively according to the notification of the watchdog unit and then outputs the new frequency, and the present frequency is replaced by the new frequency. A hardware parameter value setting unit is used for setting initial frequency and the working mode for the frequency generator and starting the watchdog unit. After the presetting period, the mainboard can not start successfully; after receiving the re-start signal, the mainboard can automatically restart under a new frequency hardware environment.

An overclocking control method cooperates with an overclocking application of a computer system when the overclocking application is started. The overclocking control method includes the steps as follows. A BIOS enters an overclocking mode according to an executing state of the overclocking application.

For applications, multitasking is a realistic need; and for a processor technology, programming is a theoretical basis of the processor technology. The problem that any processor technology cannot escape is to meet the requirement for multiple tasks on the basis of the programmed technology, and therefore the concept of time slice is achieved. The definition of the time slice or the related technology, namely a time division multiplexing technology for kernel hardware resources, is not easy to understand, and the definition or the related technology is just done in the existing background technology. However, how to define the length of the time slice is often limited by the requirements of the dominant frequency and application of a processor for real-time characteristics. According to the technology, the problem of trade-off between the time slice and actual requirements is solved theoretically and practically, and on the premise that the time slice is set, actual application (namely, on the premise that the time slice is defined as T, 2T, 3T or even more actual execution time slices can be obtained) with an overclocking effect is achieved for the application.
