Abstract

A method for testing overclock frequency of VGA includes the following steps. Step A is to receive a new clock parameter of a GPU and a new memory clock parameter, which determine the operation of the VGA. Step B is to make use of the clock parameter of the GPU and the memory clock parameter received from step A to set up the VGA through a software approach so that the VGA is operating with the clock parameters. Step C is to call three dimensional application program interfaces so that the VGA within the pre-defined time limit can execute to show a three dimensional picture in a window and output the three dimensional picture to the display connected to the VGA and executing the lighting instruction, create mesh instruction, object rotation instruction, spherical warp instruction and 3D immediate mode instruction so as to normally display the three dimensional picture. Step D is to determine whether the three dimensional picture has been normally shown on the display, the clock parameters from Step A being accepted in case of being true and an original clock parameter of the GPU and an original memory clock parameter being restored in case being not true.
