vCore - Manual or Adaptive mode?

[The_Sandman]

Hey everyone

 

 

I recently posted some questions about my overclock and i got a lot of replies and they were very helpful, thanks for that, this is an awesome community

 

 

I have one question left now that i have got myself a stable overclock on my 6600K (4,7GHz @ 1.320V):

For the stress testing with Aida64 i put the vCore to "Manual Mode". I ran 10 hours of Aida64 stress test and played some Battlefront and Battlefield 4 afterwards, so i think it's a stable overclock. Since i'm done now with tweaking my overclock, should i set the vCore to "Adaptive Mode" or leave it at "Manual Mode" to give the CPU a constant voltage?

 

Thanks in advance for your help!

If you leave the settings like EIST & C-states on in BIOS, it shouldn't force that voltage 24/7.

 

I double checked this on my own board with manual voltage & a digital multimeter, the voltage does indeed turn itself down when the CPU isn't under load, but a lot of software doesn't read it correctly, and reads only the VID (the voltage set in BIOS)

I didn't change any settings except for enabling the XMP for my memory and changing the vCore and multiplier on the CPU. So you think it will be no problem leaving it on manual-mode?

It should be fine, EIST and those other settings I mentioned are on by default.

If you're pushing it to its limits, adaptive voltage is out of the question.

 

In general manual voltage is better. Because it gets you the lowest possible temp at full load (which is when temps really matter)

 

I'm not pushing it to its limits. I managed to get 4,8GHz on 1.375V but decided to go back to 4,7GHz since it only needs 1,320V to run stable. Why is manual voltage giving me lower temps at full load?

 

(Btw: Temps are not a problem, while stress-testing i only reached a max of 57 degrees with my H100i GTX)

Ok, thanks If nobody convices me from the opposite i think i will leave it on manual then.

The CPU has its own internal setting that determines how much volts to draw at any given load and clock speed. With adaptive volts, it simply slaps on X volts on top of what it would have drawn without any OC. That almost always results in pulling more volts than required to remain stable. The benefit is only during low load situations as total power draw is allowed to drop.

 

Ok, then i think i'll go with leaving manual mode on. If i understood your explanation correctly then this is the better option than changing it to adaptive, since it will not draw more volts than required.

I seem to have a very similar setup to yours (i5 6600K/z170-A) and I was wondering the same thing! Can you confirm that manual voltage in the bios is more like a max voltage cap? Does the voltage go down when idling? I don't really know how to configure adaptive mode and I wasn't able to find a quide that explains what each setting does

When idling the voltages will go down. At least that's what i can see if i open up CPUID HWMonitor. There the voltages for the CPU when in desktop use are at around 0.8 - 0.9 Volts.

 

Hope this helps, and happy new year

I don't know where the "best answer" came from, but almost all boards come with a negative offset.

I'm using adaptive mode and using less that stock voltages and stable.
