Hi,

The thing is my ASUS rog ranger sets the v core of my i7 6700k to 1.343v when it is on auto and that is way to high. Aslo got CPU temps in the upper 70 because of the high vcore.

that,s why i decided to lower my vcore and oc a little while having lower temps.

my i7 6700k is currently running @4.2 ghz with a manual vcore of 1.180.
i did run a few bencmarks and i haven,t got any crashes yet.
The max temp i get in bencmarks is 58-60.

but... is it better to use adaptive voltage? so yes what sould the offset etc be?
i am not planning to oc any further at the moment.

Thanks for your help!

Yes. Put 1.2v and leave offset at auto. You also want to set a level on your Loadline Calibration LLC instead of auto within the Digi power control section. Level 4 is probably fine.

If you're testing an overclock use manual, otherwise you can switch to adaptive mode. You can leave the offset on auto or whatever voltage range you want. For the sake of stability, I would leave it at 1.2V. Temperature difference will be negligible.

Skylake seems to tolerate higher vcore than haswell.
1.4v seems to be about the limit.

You are correct in that it is the vcore you can tolerate is your limiting factor.
I would have no issue with 1.343 and 70c under load.

For a stress test, 85c would be about the thermal limit to stop the test.
Use something like OCCT, not prime95 or IBT which are unrealistic and do not use normal instructions.

I like adaptive voltage and speedstep.
That will reduce the vcore and multiplier when the cpu has little to do.

FWIW:
As of 5/2016
What percent can get an overclock at a somewhat sane 1.40v Vcore.

6700K
4.9 2%
4.8 17%
4.7 59%
4.6 93%
4.5 100%

Thanks it seems to work great.
1 more question i can set a - or a + for the offset.

i figured i should take the - because i want to lower the voltage when it is not under full load. Am i right?

If it stable then it's fine whatever you put.
