Method and apparatus to adjust voltage for storage location reliability

According to embodiments of the present invention, an integrated circuit such as a processor includes a counter to count an actual number of unreliable storage locations in the processor cache, at least one register to store an acceptable number of unreliable storage locations for the cache, a detector to measure a thermal environment of the processor, and circuitry to raise an operating voltage of the processor if the actual number of unreliable storage locations exceeds the acceptable number of unreliable storage locations, and if the thermal environment is acceptable.
