Question about safe voltage levels
What voltage is acceptable?
The voltage the CPU selects independently. The firmware continuously tracks and controls a vast amount of chip health data every second to guarantee peak performance for cores under stress at any given temperature. Trying to adjust the voltage manually won’t help; it may actually hurt performance by lowering maximum output and increasing average voltage over time, especially if idle voltages were turned off. If your goal was to lower the voltage, you’ve likely increased it instead.
Try experimenting—just like other users do.

LOL...I enjoyed this one...

Make sure you thoroughly understand Black's Equation. Voltage isn't a direct factor; it relates more to current density and heat. Yes, voltage can cause current flow, but strong enough current with low voltage and high thermal conditions still leads to electromigration. Similarly, if the thermal state is sufficiently low, even high voltage wouldn't pose a risk. In such scenarios, voltage would be limited by silicon stress tolerance, which is the point where it breaks down rather than causing electromigration.
Also, it seems you may have missed key points BZ was discussing in the linked videos. As an overclocker, focus should remain on managing temperature and minimizing voltage where possible (within stable frequency ranges) to achieve better control. Controlling current is largely beyond your influence—it's a result of process and material limitations.
Voltage is a part of the system, serving as the energy source. Claiming that the energy source doesn’t influence temperature or current is incorrect. Power equals V squared divided by R in fundamental electronics. Power in dynes equals V squared times current density; voltage remains integral to these calculations. Voltage and current are inherently linked. Components can be harmed simply through repeated thermal cycles.
Electromigration happens when a voltage difference exists. This process intensifies with high current densities and the heat generated by Joule effects. Because real-world testing is challenging, Black's equation is applied to estimate the lifespan of integrated circuits. To apply this method, the component undergoes high-temperature operating life (HTOL) tests. The projected lifespan under actual use is derived from test data collected.
Electromigration happens when part of an electron's momentum is passed to a nearby activated ion. This results in the ion shifting from its initial location. Gradually this force pushes many atoms away from their original spots. A break or gap may form in the conductive material, blocking the electrical current flow.
