ABSTRACT:
A system for testing a video memory reliability of a video card includes an input module, a data read/write module, a data processing module, a data comparison module, and an output module. The input module is capable of activating a testing program which includes an original image file. The data read/write module is capable of writing the original image file in the video memory from the testing program, and reading the image file data stored in the video memory during the writing process for storing the read image file data to form a new image file. The data processing module is capable of calculating hash values of the original and new image files using hash function(s). The data comparison module is capable of comparing hash values, and outputting the comparison result. The output module is capable of indicating whether the video card is normal according to the comparison result.
