Overclocking Voltage Troubles

[1Revenger1]

Hi guys, I have recently gotten a new computer and have a question about overclocking. I have an I5 6600k overclocked to 4.6ghz with adaptive mode at 1.325 volts with an auto - offset. I have a Z170 Pro Gaming motherboard from Asus, and I frequently see my voltage go over the 1.325 set. I have tested the CPU to be stable at 1.325, from what I have seen from setting adaptive mode, this is completely normal to go over. Although I don't think it should be spiking up to 1.390 volts. I know that this is safe, but I have this as a 24/7 overclocked and would rather keep the voltage lower than keeping it higher. Is there any way to make sure it doesn't overvolt over what I set to much. I would prefer if it stays below 1.35 volts.

 

Thanks!

A 24/7 overclock in offset doesn't mean the voltage is applied constantly.  That only happens in manual voltage mode.  Offset just tells the BIOS to - x amount of voltage for any given voltage it's using if possible.

That's actually dependent on the board and the technologies on the platform.

 

If I leave c-states and EIST enabled, I can use manual voltage and my CPU's voltage will downclock at idle loads. ( measured with a digital multi-meter on the voltage read points on my board)

So what would the best mode be to leave the cpu voltage on? I don't want the voltage to be at 1.325+ constantly, which it doesn't do(sorry, never said this ). I haven't messed with c-states or other settings. Would it just be best to leave it in manual?

I am pretty certain offset voltage is the same on all motherboards, where it's a set -voltage of your preferred value when available.  If they were different, OC'ing guide would be terribly confusing as one term means a different thing elsewhere.

I guess the main question I am asking is with adaptive mode, with a -offset, is there any way to not make it not go over by almost 0.1 volts?

Unfortunately I am unsure about that.  My own CPU does not like offset so I am forced to use Manual voltage ):

Alright, guess I'll try to use manual voltage for now, since it can manage itself and not use all the volts on an idle load. Thanks for the help .

Do you have a multimeter? You could perhaps contact asus and ask where to read vcore current.

Then you could see if manual actually forces the voltage all the time, or only under load.

My board only forces it under load as long as I leave c states on.

Unfortunately, we don't have a multimeter. I did some testing and for some reason, even in manual mode, it still tries to overvolt the CPU. Is there some type of voltage regulator inside the CPU? I thought they moved a lot of the voltage stuff off of the CPU with skylake.The voltages still do go below what I set in manual, so I know I have c-states on.  I am kind of at a loss here, I'll go look around in the BIOS to see if there is something conflicting, but I am pretty sure I didn't change anything other than voltage mode.

See if you have "LLC" or Load-Line-Calibration in your BIOS, try a lower setting it may help with the over-volting.

I wasn't able to find LLC or Load-Line-Calibration in the BIOS. I did turn off CPU SVID though, was set to auto before. I think it was off before because it really isn't making a difference at all. With manual, the overvolting is a little better, max I've seen is 1.36V.
