Minimum processor state?

[sinspiren]

hi guys, so I recently I starting to tickle this setting, it seems a good feature for power saving but will it affect stability and will it potentially damage CPU? I overclocked my CPU and using adaptive mode. Let's say I set the minimum to 10% and max to 100% when I opened a testbench from the desktop, this will let the core voltage going from like 0.8v to 1.275, is there any possible overshot during the process? or simply is it possible that the adjustment didn't react fast enough and cause crash otherwise should not happen? Also, fix a relatively high vcore and speed comparing to switch voltage and speed constantly which will cause more CPU degradation?  Tried to google it, it's a common topic but seems no post is related to voltage and stability discussion.

their is no reason to do this

in theory frequent voltage changes can degrade the CPU, but that's still less degradation compared to running high voltage all the time

Don't worry about it. CPU does that by default, for Intel CPUs the technology is called Intel SpeedStep.

No. Adjusting processor power states to reduce power consumption has been a thing for almost 15 years now. Processors that were around then that are still being used today are still kicking it just fine. Voltage swings do not harm electronics. The only thing voltage swings can possibly do is change the heat output and thermal fluctuations are a problem. But again, we have processors from when this feature was first used still around and still working just as well.

No. It is enabled by default since Windows Vista (or was it 7? anyways). If it breaks something, then it was broken before/manufacture error.

Power delivery is from the motherboard. So if it sucks, then it could be an issue for the CPU when it request more power. If it is able to react accordingly, then it should be no problem.  It should not be an issue if you are doing standard overclocking. If you are doing some crazy stuff just for benchmark score, then probably this feature will play against you in terms of system stability. You'll also turn off the hardware level power states features in the BIOS/UEFI.

The more voltage you push through the CPU above what it was deigned for, will accelerate its degradation. Usually, people doing crazy overclocks, don't tend to keep their CPU more than 3 years. It is either a past time of theirs, and so money goes in getting nice CPUs and spend time overclocking them, or seek for more and more performance. And the stuff you see on YouTube and competitions with LN2 or massive water cooling with ice buckets setups are just fun to beat a score, not actual setup that they use daily.

Very detailed reply, thx, so for daily use (gaming/ rendering), and want to keep cpu alive for a moderate time (5 year+) you do recommend to turn the function on?

Just set your CPU voltage to stock 1.237v theres nothing to worry about your CPU will last much longer than 5 years.
