And some quotes:
"At conditions outside functional operation condition limits, but within absolute
maximum and minimum ratings, neither functionality nor long-term reliability can be
expected. If a device is returned to conditions within functional operation limits after
having been subjected to conditions outside these limits, but within the absolute
maximum and minimum ratings, the device may be functional, but with its lifetime
degraded depending on exposure to conditions exceeding the functional operation
"At conditions exceeding absolute maximum and minimum ratings, neither functionality
nor long-term reliability can be expected. Moreover, if a device is subjected to these
conditions for any length of time then, when returned to conditions within the
functional operating condition limits, it will either not function, or its reliability will be
"For functional operation, all processor electrical, signal quality, mechanical and thermal
specifications must be satisfied."
"If you run at or below the Absolute Maximum Voltages for your CPU, you should never experience degredation or lose of life on your CPU. Overclocking will not decrease the lifetime of your CPU if and only if certain criteria are met. "
"According to Intel, "Within functional operation limits, functionality and long-term reliability can be expected." This says nothing about running over stock voltages or stock clocks. Only that you need to be stable, cool, below the maximum voltage, and mechanically sound at any speed."
"Interestingly enough, criteria 2 (Signal Quality) alludes to the idea that unstable overclocks cause CPU degredation."
