Hi guys,

I know there is another thread on this very subject but I don't want to hijack it. The OP of that thread is looking for 4.5/4.6 GHz. I'm happy to go only to 4.4GHz but I want to optimise that for fans and voltage and not sure how.

I have set my motherboard (Gigabyte Z170 K3 EU) to use an inbuilt 4.4GHz profile. Everything else is on auto.

This is the result of a CPU-Z stress test.

So this is with everything on auto. Any issues with this or can it be better?

An odd thing happened after. I stopped the stress test and came on the internet. Just while browsing, my voltage went up higher than it shows in these screenshots. The highest I saw it go was about 1.31. How can just loading the internet give me more voltage than doing a stress test??

I would also like to know, with using the auto settings, what is to stop the motherboard from raising the voltage up too high? What is the cap on it? I looked for a setting so I could fix a cap of say 1.35, but couldn't see one.
 
I've literally just hit the same point, similar temps. Going to go for 4.5 now....

Edit - Had to up the voltage to 1.35v to get cinebench and POV-Ray to run through one pass. Temps were getting into the low sixties.

Despite reading up, I am still not sure how to best deal with the voltage. Why not leave your motherboard on auto and change the multiplier, what happens?
 
Not sure why no one is willing to answer my question about volts. Can someone explain how it works please, why i cant just leave the setting on auto in the bios, and whether, if i manually set the volts, whether i will still get adaptive frequencies when not on load. Thanks.
 
Load optimised defaults in BIOS.

Change your core voltage from auto to 1.23v. Change load line calibration (LLC) from auto to extreme. Change your ram settings from auto to XMP profile 1. Change core multiplier from auto to 44. Disable Intel boost.

Save and exit.

Download ASUS Realbench. Run the benchmark. Monitor voltage and heat as it goes.
 
Thanks. Ill try those settings later.

What does setting the LLC to extreme do please? Im wary of setting something to extreme without knowing what it does. Ive googled it but its technical and i dont get it.
 
The technical explanation will talk about vdroop, and in layman's terms this means it will maintain the voltage you set and prevents it from going higher or lower.

LLC works in stages with Gigabyte boards, from low to extreme. Low will allow fluctuations in voltage, and extreme won't allow any fluctuations. Settings in between will alter the parameters.

Set the overclock without changing LLC and your voltage will fluctuate up and down as BIOS sees fit. This is not good when you have already raised it to support your Overclocked ratio.

Extreme is a poor choice of wording by Gigabyte. Set it to extreme, and then watch your voltage in cpuz as you load and unload your cpu and you should see the voltage remain rock solid.

Trial and error, and loads of monitoring/testing. That's the way to understand your overclock.

*note: I have seen articles talking about LLC working in reverse than described above. However, all the gigabyte boards I have used have worked as above. Like I say, trial and error. Set to extreme and make sure the voltage stays rock solid.
 
Thanks. I guess it seems counter intuitive to me that its better for the voltage to be always the same rather than stepping up and down to match the load on the cpu.
 
Yeah I've just checked it is, set it to high but left it at auto for now. I'm using integrated graphics for the time being so it may have a bearing but not overly bothered.

I only have auto, high and standard in the cpu vcore loadline calibration field.
 
No its moving a little bit, and that's having not run the benchmark yet either.

I set 1.23V in the BIOS, and in HWmonitor its jumping from 1.224V to 1.236V (nothing in between, just those two values).

I was sure I'd seen a setting for extreme in my bios somewhere. But its definately now only auto, high or standard. Is there another setting that I need to active to allow access to extreme mode?

I did the load optimised defaults first as you suggested. Has this somehow removed my access to this field?

Ok done that. The vcore did not appear to fluctuate. The VID did - is that ok?

Here are before and after screenshots:

Before - the result of the benchmark:

After - the results of the benchmark and a screenshot of HWmonitor:
