Hi guys so i have an i7 6700k with a Gigabyte GA-Z170X-Gaming 3 motherboard and i have a few questions.
I set the cpu clock ratio to 44 and activated the ram XMP profile, and that's pretty much the only thing i did. I left the Vcore as auto with the base vcore being 1.280V (it doesn't really let me change that anyway, i've heard that 1.28 is pretty high for being the base vcore?) Now my question is if the voltages i'm getting are safe, HWmonitor shows that CPU Vcore maxes out at 1.390V which is pretty high but when i look at it it's mostly sitting on 1.275 when CPU is on load, VID voltage (i'm not really sure what this is) is even higher and it maxes out at like 1.42V and more sometimes. Temps are 72c max. I've heard that it's best to set the Vcore as manual and not leave it as auto, but in that case the Vcore never down clocks itself when the system is idle, and i can't find any options in my bios for adaptive vcore or even offset, what do i do?

Full Specs:
CPU: i7 6700K
GPU: Gigabyte GTX 1080 overclocked
RAM: Corsair DDR4 3000mhz 16gb (8x2)
CPU Cooler: Scythe Mugen Max (2 fans)
SSD: Samsung 850 500GB
PSU: Seasonic 760W Platinum

Sorry man. I'm not familiar with that bios and i just went through its manual and don't see anything about voltage offset. I had this happen with a z77 evga board i picked a couple years ago and was upset at first but just ended up using fixed voltage, clocked my i7 to 4.4 (at 1.31v) and called it a day. Never had a problem and just sold that CPU for half of what i paid for it.

Auto voltages are always gonna be high. That's why we never use them. That said, if it's only boosting up the voltage for short periods i wouldn't sweat it. Your temps under load are a little high but not unsafe unless you're always in the 70s. That said, if you're only hitting the 70s during synthetic testing then you're ALL good.

Don't worry about the VID...

I often wonder if adaptive voltage is the same as automatic, as I think Intel dropped their in-built voltage regulator with Skylake anyway? If auto means free to go to whatever voltage it likes it could cause serious damage to hardware without the user ever knowing so manual is probably safer, but without it being able to drop lower when not needed it does seem counter intuitive.

Don't worry about the VID. That's not the actual voltage of your CPU.

Personally, I'd just set your voltage fixed. Maybe take to some gigabyte forums to see if you can get some better answers

Thanks for the reply mate.
OK so there is actually no setting that downclocks the voltage when idle on that motherboard (wow, gg Gigabyte, surprised no review mentions this).
In that case, would it actually be unsafe if i just kept it manual and the voltage never downclocks itself? i'm looking now and it's constantly on 1.260V, very rarely jumps to 1.272V and when on load it actually downclocks itself to 1.188V (i heard this is because of vdroop). So how safe is this for 24/7 use?

Then use adaptive/auto mode then if you want the voltage to go down at idle alongside with the clock speed.
With Gigabyte boards, Auto is adaptive but you don't get to put an offset on the adaptive.

But i already said that Auto mode causes really high voltages and i don't want that.

I don't see such a setting in my bios?

Alright so i'm just gonna leave it on 4.5mhz and voltage on auto, shouldn't be that bad if it only rarely exceeds 1.3V and indeed stays most of the time on 1.260 when on full load.
I also disabled XMP profile and manually oc'd memory to 2666hz and temps are lower by 10c now, damn people should be encouraging this more often.
