Embodiment Construction

[0023] figure 1 Show the flow chart of the present invention is used for the CPU overclocking method of computer motherboard, and figure 2 A schematic diagram showing the architecture of a computer main board applying the method of the present invention. The feature of the central processing unit overclocking method of the present invention is: when the power supply (Power) of computer motherboard 20 is turned on, be to allow central processing unit 201 to start (Boot) with the most stable frequency earlier, and allow central processing unit 201 to start (Boot) with the most stable frequency. Stable frequency for operating system (Operating System) loading (Loading), such as Microsoft (Microsoft TM )Windows( ) operating system, when the operating system is fully loaded, the frequency of the front side bus (FSB-Front Side Bus) of the central processing unit 201 will be changed. Generally speaking, from the point of view of the CPU, the above-mentioned most stable frequency...

Abstract

The invention discloses a central processing unit (CPU) overclocking method for a computer mainboard, comprising the steps of: step (A), setting a front side bus (FSB) of a second frequency by an operation interface of a basic input / output system (BIOS); step (B), according to the difference value between the first frequency and the second frequency, determining the FSB frequency (Fn) of each of N phases; step (C), starting the CPU at the FSB of the first frequency to load an operating system, and after finishing the load of the operating system, enabling a chip group to transmit interrupt signals to the CPU at every pre-set time, thereby enabling the BIOS to obtain the control right of the CPU, and from the first interruption to the N-th interruption, carrying out step (D) at each interruption by the CPU till the Fn of the CPU is adjusted to the second frequency; and step (D), in the nth interruption state, enabling the CPU to change the operation in the Fn when the CPU executes the BIOS, and then returning the control right of the CPU to the operating system.

Description

technical field [0001] The invention relates to a method for overclocking a processor, in particular to a method for overclocking a central processor used for a computer motherboard. Background technique [0002] US Patent No. 6,622,254 "Method of automatically overclocking central processing unit (CPU)" discloses a method for automatically overclocking a central processing unit of a computer motherboard. US6,622,254 mainly uses a frequency generator that can adjust the frequency arbitrarily and has a supervisory function, and uses a numerical method to obtain the frequency at which the computer is turned on, so as to achieve the function of automatic overclocking. After the computer is turned on (Powered on), if you choose to enter the overclocking program, Firstly, the parameters set at the last power-on will be saved and backed up for comparison at the next power-on. US6,622,254 has many flags (Flag), the purpose is to judge the current situation, as the basis for the ne...
