Computing system with automated video memory overclocking

A computing system for displaying video, comprising:

• video memory;
• a processor programmed to provide a user interface on a display after system boot, the user interface including a first user selectable button to enable the user to manually tune a clock frequency of the video memory and a second user selectable button to enable the computing system to sequentially increment the clock frequency of the video memory by a selected change in frequency through a series of overclocked frequencies, after each frequency incrementing writing data to the video memory and stability testing of the video memory data writing, and if the stability testing fails then decrementing the frequency of the video memory to a previous overclocked frequency at which the stability testing did not fail;
• and
• wherein the stability testing includes loading a test pattern into the system memory, copying the test pattern from the system memory to the video memory, reading back the test pattern from the video memory and comparing the test pattern read back from the video memory with the test pattern copied from the system memory for errors.

A non-transitory computer readable medium having computer readable instructions for performing a method with a computing system having system memory, comprising:

• after booting the computing system operating video memory of the computing system at a non-overclocked frequency;
• prior to rebooting having the computing system sequentially increment the frequency of video memory by a selected change in frequency through a series of overclocked frequencies, after each frequency incrementing writing data to the video memory and stability testing of the video memory data writing, and if the stability testing fails then decrementing the frequency of the video memory to a previous overclocked frequency at which the stability testing did not fail;
• and
• wherein the stability testing includes loading a test pattern into the system memory, copying the test pattern from the system memory to the video memory, reading back the test pattern from the video memory and comparing the test pattern read back from the video memory with the test pattern copied from the system memory for errors.

A method of graphics processing using a computing system, comprising:

• booting the computing system;
• after booting the computing system operating video memory of the computing system at a non-overclocked frequency;
• prior to rebooting having the computing system sequentially increment the frequency of video memory by a selected change in frequency through a series of overclocked frequencies, after each frequency incrementing writing data to the video memory and testing the stability of the video memory data writing, and if the stability testing fails then decrementing the frequency of the video memory to a previous overclocked frequency at which the stability testing did not fail;
• and
• wherein the computing system includes a processor with error correction hardware and the video memory includes error correction storage cells in communication with the error correction hardware, the stability testing comprising running a 3D memory intensive application, sensing for one or more error interrupts from the error correction hardware, if no error interrupts or error interrupts indicative of correctable errors are detected then deeming the stability test a success or if error interrupts indicative of uncorrectable errors are detected then deeming the stability test a failure.
