Hi Guys
Im using a ryzen 7 1700 @37.25 GHz, but i also lowered the voltage by 0.1125V. Now my Question: Does Overclocking still reduce the lifespan of the processor if you drop the voltage?
I hope you understand the question, i am not really sure how to explain it

I'm going to assume you meant 3.7GHZ or that is a new world record by a large margin :3

If you are undervolting and the temperature is good, baring random defects (and of course, dropping, wetting, smashing, etc), the processor should die of obsolescence long before anything else.

oh yeah i meant 3.725GHz, the multiplicator is just 37.25 so i just didnt think about it.
I know that the processor will last me a lot longer that the performance will be enough, but i would like to know if it theoretically dies faster because it is overclocked, but with less voltage

in theory you'll reduce lifespan of the CPU just by using it, but lowering voltage while overclocking could increase or decrease total lifespan. This is because CPU lifespan is determined by current as long as the voltage isnt absurdly high for its operating temperature (hence why 1.8V or more is used when cooled by liquid nitrogen without killing the CPU).

Theoretically, physics predicts some amount of 'wear' per cycle  by the processor, so running at a higher frequency constantly, all else equal, would cause it to wear out faster, but that sort of wear is entirely inconsequential in practice. Heat is much, much more significant. If your processor is running cooler while overclocked and undervolted, it should have it's lifespan extended..
