Abstract
The present invention performance enhancement and reliability maintenance system and method pushes a processor to its maximized performance capabilities when performing processing intensive tasks (e.g.,D graphics, etc). For example, a clock speed and voltage are increased until an unacceptable error rate begins to appear in the processing results and then the clock speed and voltage are backed off to the last setting at which excessive errors did not occur, enabling a processor at its full performance potential. The present invention also includes the ability to throttle back settings which facilitates the maintenance of desired reliability standards. The present invention is readily expandable to provide adjustment for a variety of characteristics in response to task performance requirements. For example, a variable speed fan that is software controlled can be adjusted to alter the temperature of the processor in addition to clock frequency and voltage.
