Each processor is programmed with a maximum valid voltage identification value (VID), which is set at
manufacturing and can not be altered. Individual maximum VID values are calibrated during manufacturing
such that two processors at the same frequency may have different settings within the VID range. Please
note this differs from the VID employed by the processor during a power management event (Adaptive
