Voltage levels on the OC CPU
Voltage levels on the OC CPU
The voltages on your CPU can be increased without bound if your system stays cool, but there are practical limits based on hardware design and power constraints.
Voltage reflects the energy stored in motion at the smallest scale. There’s a moment when temperature becomes irrelevant. You can chill a wall completely, yet an impact from a car will still penetrate it. The flow of electrons between atomic layers works similarly.
The area below where temperature isn't a factor is actually lower than commonly assumed. For Intel, it's approximately 1.4V for Zen 2 and possibly even lower. Between 1.7 to 1.8V marks the point where the chip begins to fail.
The input voltage needs to stay fixed at a specific level. Even with extreme cooling using liquid nitrogen, there will come a limit where "infinite voltage" could damage the chip.
Using LN2 removes restrictions on cooling power, allowing higher voltages. The motherboard BIOS will have reduced capabilities. If you can boost the BIOS limits through advanced modifications, you reach the hardware's maximum.
