Solution Overview

Problem

Existing overclocking methods in computer systems are inconvenient and prone to causing damage, and during dynamic overclocking, CPU operations are unstable due to external interference during frequency adjustments.

Innovation Solution

A computer system comprising a CPU, a power module, and a control module that generates a work voltage and clock domain signal, where the control module adjusts the voltage and frequency by adding a rated and external voltage to stabilize the CPU operation during overclocking, using a Phase Locked Loop Circuit for sampling and stabilization detection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If dynamic overclocking is performed by software setting to increase CPU clock rate, then CPU performance is improved, but CPU operation becomes unstable during frequency adjustment

Engineering Contradiction:
ImproveCPU performanceVSAvoidCPU operation stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies preliminary action by pre-adjusting the voltage to a temporary higher value before increasing the clock frequency. This preparatory voltage adjustment ensures that when the frequency transition occurs and causes vibrations, the CPU already has sufficient voltage headroom to maintain stable operation throughout the transition period and subsequent stabilization phase.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements beforehand cushioning by adding an external voltage component beyond the rated voltage requirement. This voltage cushion acts as a buffer that absorbs the destabilizing effects of frequency vibrations during overclocking transitions, preventing abnormal operations and ensuring reliable CPU performance during dynamic frequency changes.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

2Productivity

If traditional jumper adjustment on motherboard is used to change clock rate frequency, then overclocking can be achieved, but convenience is reduced and component damage risk increases

Engineering Contradiction:
Improveclock rate frequencyVSAvoidoverclocking convenience
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical jumper adjustment system with a software-based control system. The control module communicates with the power module and clock generator through electronic interfaces, allowing frequency and voltage adjustments to be made via software commands rather than physical motherboard modifications. This substitution dramatically improves ease of operation while eliminating the risks of component damage associated with mechanical adjustments.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

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.
