CPU Voltage

I'm learning how to overclock my CPU considering it hasn't really been been fully utilized the whole time I've had it and its probably a good idea to overclock considering I have the K model and brought my shit with OC in mind

I've got 4.8ghz at 1.33 volts stable. My temps have never gone to 60 before or anything like that ever, they were 40 whilst testing in TF2 Fortnite and high 40s in Cinebench.Thermals are not the issue.

What im concerned about is whether the voltage itself will cause a lot of damage, as in not work in 6months.

Im using LLC mode 2 on my Asrock Taichi z370 board and the Voltage mode is 'stable', stock, whatever that means instead of 'OC mode'.

In Hwinfo64 the max vcore doesn't go above 1.328 and averages at 1.317. using the Intel Diagnostic Test where they give you a CPU load, the VID goes to 1.415 which is what it does on every voltage i've tried on this frequency, but thats apparently normal because apparently VID is just the voltage that the processor is designed to want, not what it gets.

it seems fine but i understand that the voltages that are shown in these sensor monitoring softwares are not accurate and sometimes u get a lot more than u put in knowingly.

on doing research on what other people have found with my i5 8600k and same motherboard, people are saying that any VCore below 1.4 is ok, with 1.35 being standard, however others are saying that they managed even 5GHz with 1.29 or whatever and that 1.35 for 4.8GHz is 'high'

just posting for a more detailed answer to my specific situation because basing my shit on other ppls shit that is slightly different to mine is not good

is this ok to use or not?

im aware my voltage recorded isnt even on the higher side with some people at 1.37 in hwinfo64 but im more concerned about the stability of the voltage being safe i guess

Different models of CPU have different voltage tolerances so I can't really say what's a safe voltage in your cpu. But generally..

Looking at specific clocks, recommendations are hard to gauge since few people actually want to spend money on testing what exact voltage destroys a cpu. Often people recommend lower voltages than what are actually still safe because they only know that "this voltage is safe" based on their own experience.

On the flip side, here isn't a cutoff between no damage and an insta-fried CPU, it's a sliding scale of how much degradation happens.
With a borderline voltage, the CPU may degrade slowly, causing the maximum stable clocks to decrease a few hours/days/weeks/months down the line. If you're planning on replacing the CPU in 1-2 years anyways you can afford to push a bit higher than if you want the CPU to last forever. (and If you're fine with trying to balance the risk of a slightly slower cpu with the opportunity of a slightly faster cpu.. generally though, fiddling with overclocks to get the absolute maximum out is just a hobby/another way to waste your time with your computer. You won't actually notice 3% more or less performance when you use a computer)

Temperatures also have an effect on stable clocks (and higher clocks cause a somewhat higher heat output even on the same voltage). Also, chips all have some defects, and how many defects yours has affects the maximum overclocks.

Because the damage potential increases exponentially with voltage, going 0.03V lower than a voltage that causes no damage in 1 year should pretty much never cause any damage (assuming relatively similar temperatures.) An unoverclocked CPU will usually last a decade of 24/7 stress testing (likely far longer than many other components of your pc)

Thank u

Iv changed it to LLC 3, 1.34v and AVX offset 3 because i think this is safer
