Help needed for a simple overclock! 6700k-Asus Maximis VIII Ranger

Hello to the community.
Total noob here and to the forum so be kind. I'm trying to make sense through videos and guides but my knowledge is limited. I'm trying to get a nice overclock to use daily. Nothing extreme, don't want to push that much.

Some data first:
CPU: i7 6700K
Cooler:Noctua nh d15 Dual fans
Ram: 2X8gB corsair vengeance 3000 MHz
Mobo: Asus Maximus VIII Ranger

I did a lot of research before overclocking my 6700k but I mostly followed this guide:



I have xmp enabled.
I managed to get it stable at 4.6 GHz @ 1.30v (all readings are VCore ones, not VID). I'm getting some spikes from HWinfo, with the voltage reaching 1.328v. Stress test gave me average temps of 52 and a max of 67.

Then I tried to get it to 4.7 GHz. My pc was stable with a voltage of 1.360v quite a big step from 1.30v but it's fine I guess. My average temp while stress testing was 53.9 C and my max was 70 C.
I'm using adaptive mode at 1.360v with a negative offset of 0.01. Now this is hard for me to understand. I've read almost everything and I couldn't understand what applies to my case so I don't know if that's a good setting.
Also HWinfo for the 4.7GHz setting gives me spikes of maximum 1.408v (rarely) and mostly spikes are of 1.392v. Why is that? Can I get it to be more stable? Can I fiddle with any settings to make it not go above 1.40v?
Stress testing (manual voltage) gives me a constant voltage of 1.392 on HWinfo with llc at auto and 1.376 with llc at level5 out of 7. Should it be like this?
Then why does this limit break when changing to adaptive voltage and goes over 1.4v?

I also selected CPU Load-line Calibration at level 5 out of 7 on my motherboard.
Any suggestions about these voltage spikes (if they can be avoided), any ideas about making my settings better or even reassurances that I made everything perfect are welcome. (kidding) 😮

These are some screenshots from a stress test. I've done longer ones of course, with the same settings so I can guarantee this is stable.

I will be happy to provide any other screenshot that might be needed. 😄

Adaptive voltage is just that "adaptive" It gives the motherboard more leeway with voltage to adjust to what load it senses. If you were to run something like Prime95 that spike would likely increase a bit more because of the AVX2 instruction set. If you don't like the spikes (which won't hurt anything) then you'lll need to use manual mode or offset mode in voltage control with the LLC setting. On my Hero I used level 6 for the most part. But you may find that "if" you run a heavier load the system may BSOD/freeze because of a lack of voltage.
Judging by your temps, I would leave it just the way it is. You do have headroom to cool the extra voltage and it's not likely to hurt your system in any way.

Hi g4747

You can leave it as is as johan45 says or to get the voltage closer to 1.360v try using a little more offset voltage.

if it's stable at 1.360v and drawing up to 1.408v under load try using a negative offset of -0.048v, this should keep the voltage at 1.360v or close to it.

If you get a BSOD try a negative offset of -0.043v.

If you would rather see a rock voltage, which is my preference, set it to manual and the voltage desired and it pretty much stays there. Pretty much every 6700 will hit 4.5 to 4.6 GHz. Getting last this usually takes better cooling and more juice on the Vcore. *Often if you want to keep the temps down with the higher clocks it takes delidding this chips.**
