I'm currently overclocking my I7 6700k for the first time. It has been many years since I last overclocked and I'm just wondering if you guys think that the configuration I have is all safe to run 24/7. Take a look at the pic below and let me know what you think. Is this fine or should I clock it back a little bit?

The key safety metric is vcore.
It looks like you are at 1.4v for a stress test which is ok.
Your max temperature is 85c which is about right.
Under normal conditions, it will not stay there constantly.
If you have not yet done so, implement adaptive voltage and speedstep.
That will reduce the multiplier and vcore when there is little to do.

What is your oc multiplier?
Did you get a good chip?

What percent can get an overclock at a somewhat sane 1.40v Vcore.

I7-6700K
4.9 5%
4.8 21%
4.7 64%
4.6 96%

I know it's simple. I'm just asking to see if anybody has any more experience with this CPU who can tell me if this is all safe to run 24/7.

if you don't inject more voltage it's always safe , you can overclock it to 4.7 ghz , but the kaby lake probably offers you even more . if you buy an asus motherboard it's even safer , they do the overclocking for you , with one click.

I have had to put in a bit more voltage. I have had to put it up to 1.4v to keep this overclock stable. The Asrock board I have now offers one-click overclocking too however With this it is only stable up to 4.4Ghz and doing it manually I've managed to attain 4.7Ghz. So even if I did have an Asus board I'd still do it manually anyway.

Speedstep is enabled however I don't seem to have the option for adaptive voltage.

My multiplier is at 47 with a Base clock of 100MHz. I can only assume I got a good chip, I haven't had any problems with it. I can't OC to 4.8GHz though as it is not stable at 1.4v and I don't feel comfortable pushing the voltage higher than this.

Looks like you have a good chip.
Adaptive voltage is called by different terms, depending on the motherboard.
The intent is to lower vcore and the multiplier when there is little to do.
Run cpu-Z; at idle, you should see a multiplier at 8 or so and a vcore in the 0.9 range.
In windows power management, you also need to set the minimum cpu at a low number like 5%

I can't seem to find any adaptive voltage control in my UEFI settings. I have the voltage fixed at 1.4v. I have set the minimum cpu to 5% and that works fine for turning my clock speed down during idle.

What is your motherboard make/model?
If the vcore reduces at idle, you are good.
If not, there is likely some option that will accomplish the same thing, but by a different name.

It's an Asrock Z170 extreme6. The voltage doesn't lower when idle, it stays at 1.4v and I can't seem to find a setting to lower it.

Some menu items may be hidden and unlocked unless you select advanced options or manual mode or such.
Possibly also, your windows power options may need to be balanced not performance.
Is your bios current? do not update unless you see a likely fix.

There seem to be a lot of hits searching with something like "Z170 adaptive mode"

I have found it now. I had to set an offset voltage rather than a fixed one. Thanks for all your help.
