Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0041] Such as figure 1 As shown in , it is a schematic diagram of the relationship between the CPU operating frequency and the CPU core voltage (current), which is represented by figure 1 It can be seen from the above that in order to make the CPU run at a higher frequency, the CPU needs to have a stable core voltage (current). Overclocking is usually done by adding a bias to the CPU core voltage (current) to ensure that the CPU runs at a higher frequency. Can run normally and sta...

Abstract

The invention discloses an overclocking control method and an electronic device. The overclocking control method comprises the steps that an existing current value of a CPU and a current temperature value of the CPU are obtained; the current bias quantity is determined based on the existing current value and the current temperature value; the current bias quantity is added for the current temperature value of the CPU, so that the CPU controls running of an operation unit based on a biased current value. In the overclocking control method, current biasing is conducted on the CPU to achieve overclocking control, the overclocking control can be directly performed based on the real-time current and temperature of the CPU, the overclocking control method can be applicable to any specification of single CPUs, accurate overclocking control can be achieved without testing and parameter finding, and thus the accuracy rate of overclocking control is improved on the basis.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to an overfrequency control method and electronic equipment. Background technique [0002] In a computer, in order to pursue the ultimate pursuit of interface display or operating speed, the computer's central processing unit (Central Processing Unit, CPU) is usually overclocked, that is, the operating frequency of the CPU is increased, so as to achieve better display effect or faster The speed of operation brings users a better experience. [0003] At present, the mode of passive overclocking is usually adopted, that is, the operating frequency of the CPU is increased by adjusting the ratio and voltage. [0004] However, in the above overclocking solution, it is impossible to find an optimal parameter to control the operating frequency of the CPU due to the difference of the single CPU, resulting in a low accuracy rate of overclocking control. Contents of the inventi...
