The RealTemp Power Limits stuff was for Core i CPUs before Sandy Bridge. I never received any feedback about this feature so I forgot about it. I'll try to remember to block this for Sandy Bridge CPUs in the next release since Sandy Bridge CPUs use a different register to control the Power Limit settings. I have been working more on ThrottleStop recently. If you click on the ThrottleStop - TPL button, it might give you some ability to control these settings but many manufacturers have decided to lock the new Power Limits register so changing this from within Windows might not be possible. If you want some control over the CPU multiplier then that's a good reason to try ThrottleStop too. With Sandy Bridge CPUs, I haven't discovered a way to increase the multiplier higher than what you boot up at. I am not sure if this is possible anymore. Don't waste your time trying to calibrate your temperature sensors. I haven't done any in-depth testing of Core i processors so I have quit making calibration recommendations. Just keep in mind that Intel's temperature sensors were never designed for 100% accurate temperature reporting. Intel has used a variety of sensors with a variety of issues over the years. The only thing that is consistent is how vague Intel has always been about the sensors they use as well as what their sensor calibration procedure is.
