This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.
Be warned:
- Anon is often crazy.
- Anon is often depressed.
- Anon frequently shares thoughts that are immature, offensive, or incomprehensible.
If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

Doesn't undervolting damage parts over time?
In what possible way? Genuinely curious ๐๐ฝ
Lower voltage = higher current for a given power. Guess if you simultaneously reduce power you probably are okay
I think you're totally right for a load that needs a certain amount of power. But a CPU just needs to be able to flip transistor gates fast enough. They don't draw more current at lower voltage, so the lower the voltage, the lower the power. At some point, too low of a voltage won't let them flip fast enough for a given clock speed (or, eventually, flip at all)
