Abstract

The invention relates to an overclocking test method for multiple core processors, which comprises the following steps of: selecting i core processors from all the core processors as i test processors; according to the number of the core processors, i value and a normal frequency level of the core processors, calculating an appointed frequency level; generating i pressure executing threads, and binding the i pressure executing threads with the i test processors, thereby utilizing the i pressure executing threads to respectively pressurize the i test processors; when the frequency levels of the i test processors all reach the appointed frequency level and all the core processors are not tested at the appointed frequency level, reselecting new i core processors as new i test processors; and repeating the steps till all the core processors are tested at the appointed frequency level.

Description

technical field [0001] The invention relates to an overfrequency testing method of a multi-core processor, in particular to an overfrequency testing method capable of testing multiple overfrequency levels of a multi-core processor. Background technique [0002] SpeedStep is a frequency reduction technology designed by Intel (INTEL) processors for energy saving, and was previously applicable to notebook computers (notebook, NB). It enables the processor to switch between high, medium, and low frequencies; usually the frequency drops to a lower frequency when using battery power, and returns to a higher frequency or even runs at full speed when using AC power. INTEL's Nehalem and Sandy Bridge series processors increase the overclocking function on the basis of SpeedStep technology in order to improve efficiency on the basis of energy saving. The multi-core processors of the Nehalem and Sandy Bridge series have the overclocking characteristic that the highest overclocking leve...
