Chart on CPU Electromigration and Degradation
Thread will remain inactive for an unspecified duration. It's uncertain whether I can obtain sufficient details regarding specific architectures and their desegregation rates.

Hello Community! For those newer or more concerned overclockers, this thread aims to provide a solid understanding of suitable voltages for your CPU before any degregation begins (i.e., optimal settings for continuous operation).
I'll discuss overclocking on YouTube, which effectively clarifies the role of high voltages in CPU performance. The key factor is the current drawn, measured in amps, which depends on electron flow and charge movement. This explains why LN2 environments allow for higher voltages—less current is needed at those temperatures. Temperatures are critical because they influence current through the chip, even though the material remains stable chemically.

@Robert Cook doesn't really provide much detail in those videos, focusing mainly on opinion and guesswork. That's the issue with most of his content I've encountered.
He also claims that amps harm CPUs rather than voltage, but he says the Iccmax shown on the data sheet will damage your CPU. The sheet lists 100 A as the limit for Skylake quad-core unlocked chips, and if you check the power usage charts for the 6700k/7700k models, it's evident they often draw over 100 A (using the formula I=P/V), which suggests he might be incorrect.
I'm not entirely convinced by that argument. He mentions using higher voltages with LN2 to cut current, though I think reducing heat is more critical since electromigration depends on temperature as well. Black's Equation outlines the relationship: mean time to failure equals A divided by (current density squared) times exp(Q/kT).
