If you clock a P3 from 1333mhz to 1700mhz without modifying the voltage and it runs stably at that speed[for nearly 5 years BTW], it will run at that speed for the projected life of the CPU.
Yes, but the projected life will be reduced because of the increased current and temperature.

Electron migration ONLY applies to situations where more than the rated voltage is applied the component in question.
First, "electron migration" is normally called "current". However, "electromigration," which involves the migration of atoms, not just electrons, applies whenever ANY current is flowing (no matter the voltage level).
The DEGREE of electromigration varies with the amount of current and the temperature in a non-linear manner.

Overclocking will NOT degrade the life of any electronic component.
Of course it will, as overclocking increases current.
For example, here's an excerpt from work from 15 years ago:
particularly]http://www.stormingmedia.us/49/4975/A497582.html
electromigration in metal lines, power busses and signal lines, hot carrier effects in devices, and voltage drop in power busses. In addition to process parameters, all of these effects can be shown to depend on current flow in the circuit. More specifically, electromigration and hot carrier induced degradation are both long-term effects and are related to the average current flow over time under all possible input signals that the design experiences.
Wow an intelligent response! I'm glad you posted that link, it backs up the points I'm about to make. Ok here we go...
First, The temperature difference between stock speed and the OC'd CPU in question is 2C. Hardly anything to be concerned over.
Second, Since there seems to be some confusion, let me explain the difference between "electron migration", "voltage" and "current". Current is a measurement of strength of the flow of electrons through a pathway. Voltage is a measurement of speed of electrons through a pathway. Electron Migration defines the process by which electrons "migrate" from their intended and or designed pathway to other areas of the device. This effect can and does cause interference in electronic devices and in the case of CPU's, causes errors in the execution of instructions. This effect can become a cascading chain reaction which may cause the "death" of the CPU. This effect is aggravated by increased temperatures and voltage.
Third, Increasing the speed of a CPU only increases it's frequency[measured in hz], not it's current[measured in amps]. Because of the way CPU's receive their power, the two are not directly intertwined. Also because of that method, increasing voltage will increase current.
Fourth, Electron Migration is present in ALL electric devices regardless of type or source. The degree of persistence of electron migration depends greatly on the quality and type of materials used, manufacturing methods as well as environmental operating conditions.
Fifth, Overclocking will not cause any long-term damage to any electronic device even if it's temperature raises slightly. It may cause malfunction, but not permanent damage. As long heat is given a method by which it may "bleed" away from the device in question and voltage is carefully and properly regulated, the device will last it's expected lifetime. By way of comparison, if I were to drop the voltage of the aforementioned Pentium3 to .9 volts and run it at whatever frequency that voltage would allow, the CPU would outlive us all.
Sixth, Electron Migration does NOT equal current! Get that misinformed nonsense out of your mind.
