First of all I have to give Kyle props for being the first website I saw with any information posted on this Prescott voltage issue. It apparently is one of the new features Intel is using to keep these beasts cool. The processor senses when it's getting too hot and lowers the voltage to help cool itself off. The heat production of these processors is simply insane. If they were to keep the processor at 1.525v all of the time it would take way better cooling than any OEM would ever put in their systems. We all heard enough about Intel's struggles to go to the 90nm process and the delay the prescott and other products saw because of this. I don't believe they really fixed the issues they were having. I believe they used a bandaid and shipped it out anyway! Of course I can't prove this but it's just what it smells like from here.
