i7-6700k overclocking

I have had my system for about two months. Around Christmas I got around to overclocking it. I am still learning so I just used the built in overclocking feature on my Asus z170-A. Just now I noticed that it was running as 1.4v 4.5Ghz. I thought 1.4v was a little high. Also I didn't like the built in overclock feature so I used the manual settings and set the i7-6700K to 1.35v 4.6GHz. Temps seem about the same as before.

 

So is 1.35v 4.6GHz good? It runs at 62c load and 27 idle so it has good temps. Can I up it to 4.7GHz? Is 1.35v too high?

1.4v? Skylake is rated to 1.5, but hitting that is probably gonna cause something to go boom fall down

 

That's a good little 600mhz oc, I'd say try pushing it a little higher but it aint that good of an idea

So then should I up it to 1.4v again? Probably just going to leave it at a 600mhz overclock. 100 extra mhz is not worth it I don't think.

if it's stable, stick with your current voltage. experiencing crashes? push to 1.37v

1.35V is a rather safe voltage. The highest voltage I can say that would be still be sane for that CPU would be around 1.44V. Although 1.5V won't kill it immediately and it won't damage it while it's running either (unless the heat kills it), you need to consider that the VRMs on motherboards need a few cycles to get their crap together. That means that for a period of about .0005 seconds during the initialization stage of startup, the voltage can sometimes be up to .3V higher than your current setting. 1.8V to a Skylake CPU, even for just one cycle, would fry it.

 

I don't want the above paragraph to scare you, it's the truth but there are also safeguards between the VRMs and the CPU itself. Unless you set the voltage insanely high (1.5V for example), no harm will come to your CPU.

 

This is how I generally think of voltages on Skylake chips:

1.25V: Won the silicon lottery

1.3V: Cool

1.35V: You've made some small changes

1.4V: Man, you go hard

1.45V: Mate, be careful

1.5V: But, why

>1.5V: No.

cool, that makes more sense now.

Also built in OC tools in general have loads of headroom so would say up the multiplier a few times with same voltage. But it is a good point of refference.
