i7 6700k - what is the true voltage?

[GEE93]

I appreciate this may have already been answered somewhere but I am yet to see an actual answer.

I am new to OC and decided to look into OC my i7 6700k from stock 4.0 ghz to 4.5ghz following guides like https://rog.asus.com/articles/guides/guide-overclocking-core-i7-6700k-on-the-maximus-viii-extreme/ . I started by setting the voltage to 1.325 in the bios and ran a stress test using RealBench and everything was fine so I decided to lower the voltage. In my bios I am currently at 1.26 for the core voltage but when I run a stress test I noticed that in CPUID HWMonitor the core voltage is a lot higher than that set in the bios. What is the reason for this? Is my cpu running at 1.260v or 1.312v as seen in this screenshot https://gyazo.com/b48f4ca3b3f31874f11fbde22921c608? From what I can tell when idle my pc is at 1.280v and when under full load 1.312v but why are the values higher than the 1.260v that I set in my bios?

Any help is much appreciated especially if you advise me on how to get more accurate voltage readings.

The CPU requires more power when under load, so more voltage=more power

I understand that but why would I set the bios voltage to 1.30v when in reality it is going to exceed this by a fair amount. For example if i set the bios voltage to 1.25v and run a test under 100% load then CPUID HWMonitor shows a max voltage of 1.296v which is close to the original voltage I wanted to test. My point being that to test my cpu's stability while running at full load at 1.30v I have to actually set the bios voltage lower than this.

What board do you have? What setting are you using for LLC? Auto?

I'm using Asus Maximus VIII Hero and I was using auto for LLC but I ended up following a YouTube vid to overclocked to 4.6ghz at 1.31v LLC6, appreciate the response though

A higher llc can cause higher voltages...why I asked.

Glad you got it sorted.

I have a 6700k at 4.7ghz on an ASUS MAXIMUS VIII HERO board. In BiOS I set the voltage to 1.285V and according to CPU-Z, it idles at 1.309V, and will randomly drop as low as 1.22V and spike as high as 1.37V
