Voltage Problem i7 6700k

[Maxido]

Hey guys,

after I finished buliding my gaming desk - if anybody is interested:

- I decided to upgrade my hardware.

I got an intel core i7 6700k with the Asus Maximus VIII Hero .

Like many people complain, I also realized the high stock voltage but I set it down to 1,15 volts and had no problems.

After that I started overclocking.

I got it stable @4,5 GHz with 1,25 volts on manual core voltage.

Because I don´t want the CPU to run all the time at 4,5 GHz and higher voltages I switched to adaptive mode.

Here the bios settings:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

But thats where the wierd stuff showed up.

After starting windows the voltages got to 1,264 or even 1,28 volts even if I just start google chrome or something.

On load tested with cinebench the voltage got to about 1,248 like I set in the bios.

Is this normal or did I miss a bios setting?

I just tested the same on manual mode again.

Even there I have 1,264 volts on idle and 1,232 volts testing with cinebench but not as bad as adaptive mode.

Hope you can help me

Remove the adaptive mode and enable Intel Speed-Step

But if I set it to manual (Speed-Step is enabled) the voltage won't drop.Then it's running with 800 mhz and 1,248-1,264 volts.

Then there's something wrong.

But what's the purpose of adaptive mode if it should even lower voltage on manual mode ?

Adaptive adds voltage to only the turbo.

But manual mode holds the voltage on idle and on load.

Try looking for a setting called 'C-State'

[WereCat]

It should be normal for voltage to go above what you set it to when stress testing it in programs like Aida64 or Prime95 for example. Other than that it shouldn't go above. If it is nothing significant like 1.3V-1.43V then I wouldn't really worry about it especially if it is 1.264V....maybe there is just small offset somewhere.

C-states is set to auto

Ok good to know.

But why sometimes 1,28 volts.

Should I leave it at adaptive or switch to manual now ?
