Hi guys, I'm having some issues with my motherboard and it's confusing. I'm not sure what's wrong with it, especially since I can't use normal voltages for my chip. I usually test my OC with OCCT, but even at 1.23v it starts to make errors. My voltage settings are 0.95 and VCCSA are 1.05 atm. I've tried different values. Also, the temperature is a problem because I have an 212-evo and can't test very high voltages. I want to stay safe with a max of 4.5 volts without causing microstutter in games. Hope someone familiar with Z170P boards can help!

Specs:
i7-7700k 4.5 1.248v
212-evo
Asus Z170-p
16 gb HyperX Predator 3000mhz
PSU:Zalman-500LX

No. You didn't conduct sufficient research on this issue. The outcomes won't be uniform for all users because the silicon quality differs under the hood. Also, what

If the system keeps crashing despite auto overclocks, choose a power supply that supports overclocking. Your current PSU isn’t strong enough to handle the additional load. I’m suggesting a bit more power to meet the CPU’s needs.

but why the high vcore for 4.5? is it a motherboard issue or just bad luck with the cpu silicone lottery? and it's not crashing, only errors during OCCT tests.

The motherboard is configured to apply a slightly higher voltage than required by default. However, despite this adjustment, achieving a consistent 4.5ghz overclock remains challenging.

4.5ghz isn't sufficient. Below is a summary of Silicon Lottery's performance data for the 7700K:

These results indicate that the overclocking isn't reliable. Your power supply may not handle the additional load.

It seems you're confused about why your PSU forces the CPU to use higher voltage. You're worried because some people have issues with voltage settings and it affects performance, causing microstutters in games.

What it sounds like is lack of OC knowledge on your part. OC isn't just bumping up the multipliers and vcore to get faster speeds.
There's multiple settings that have to be adjusted for OC to see success. Disabling any and all eco settings like c-states, power phase controls, current limiters etc. There's also LLC that will need adjusting.
And that doesn't mention occt. Occt uses linpack, and AVX technologies which will give a false impression. While the cpu says it's at 100% loads, it's really not, it's closer to a 120-130% workload on the cpu. So temps are going to be far higher than can be expected for gaming. Occt also isn't a stable 100% load, it bounces rather erratically between @ 80% and 100%, so you'll not get a good baseline temp.
I'd strongly suggest you go into bios, reset to factory defaults and then start reading. Asus ROG forums is an excellent place to start. Those boys there are all about OC. What you are looking for isn't just specifics, but the theory. OC theory is all the same, it'll apply to any skylake/kabylake cpu on any mobo. Just the names might be different.
What you'll be looking for is what ppl have tried, what seems to work better, what failed to make a difference, what's getting adjusted or disabled or enabled.

No. You didn't conduct sufficient research on this issue. The outcomes won't be uniform for everyone—silicon quality differs under the hood. Also, what was mentioned by @Karadjgne in the post needs further clarification.

It is activated by default, which makes the "Internal PLL Voltage" parameter somewhat unclear to me.
