Hey guys, so I'm in the process of putting together a new build based around the 3900X and the ROG STRIX B550-E. I'm not really looking to push a high overclock on it, just maybe locking it in at something like 4.2GHZ, but I was wondering whether or not the voltage you set for it (say something like 1.3V) would be constant or whether it's something that decreases/increases like the CPU frequency depending on demand?

Could someone school me a little bit on voltages for overclocking?

The reason I ask is because right now I have a 2700x on stock voltage and at idle in CPU Z it floats around between 1.4 and 1.45. That seems crazy to me. A few friends with 3700X have reported similar.
That level of voltage is definitely going to degrade the CPU long term, as well as the high amount of additional heat. It would surely make more sense to cap it at a certain number, but my question is whether or not that keeps the CPU running at that voltage 24/7 or if it's just a maximum limit?

An AMD rep made a thread on Reddit last year claiming the voltages were just the result of spiking because they were being probed by the software (like Ryzen Master or HW Monitor) and that CPU Z would show the true voltage. Everyone in that thread seemed to be happy with that answer (I guess for them the voltages were much lower), but when I check CPU Z my voltages are definitely showing as around 1.45.
They've already said anything above 1.35 isn't recommended, and I'm sure someone else has said the limit should actually be closer to 1.31 for daily use.
That's why I want to set the clock for all cores to 4.2GHZ but also cap the voltage. I'm just not sure if capping the voltage keeps it at a flat rate or if that's just an upper limit that gets set.
