adaptive voltage & Kabylake

Hello all,

 

I have a strange thing when overclocking my CPU ...

I have followed a lot of guides that all advice to set the Vcore to adaptive after finding the suitable voltage for your overclocking and I did but...

the problem now is when I set the Vcore in bios to adaptive and set the value to 1.310V like in the picture below 

after saving the value and restarting/booting to windows and check with CPU-Z or hardware monitor the voltage goes up to 1.376v (spikes ) and run at stable 1,344v in benchmarks and load like apps and games (which is still higher than the set voltage in bios)

 

this is my overclock settings 

 

I have tried some methods to try to limit these voltage spikes as I saw in some guides:

1-setting CPU load-line calibration to level 5 helped to reduce the spikes to 1,344v

2-IA AC load line and IA DC load line to 0.001 gave me random BSOD

none of the above methods helped ...

 

so is there anyone here overclocking kabylake CPU's and using adaptive voltage can help ??

 

 

using Asus Strix z270e with latest bios 9060

Then lower the voltage to like 1.280v and see if you get the 1.310v with adaptive.

 

Also, lower LLC to standard/ level 0/1.

 

tried to lower the voltage to get a lower spikes but that was not stable even if the voltage spike up to higher value than the 1.310 which should be stable 

 

what is the LLC ?

LLC = load line calibration. 

 

The reason why it wasn't stable is due to the heat i feel because LLC of level 5 is like the highest which is just too much for say your cooling solution, so, lower the LLC to the lowest level which should be 0 or 1 then adjust the voltage from say 1.290v, something close to the 1.310v and work your way up or down until crashes then add like 0.050v to compensate for your normal program usage and stress testing.

aha I see
well I don't know why even though the temps were well below 78C

I will try what you said and get back to you after that 

 

 

thanks for the help

I reverted back to manual voltage with 1.310v because I was getting freezes or BSOD that I had to restart my PC while gaming 

That is happening because your method is a bit off, while you can leave the offset at Auto it is best to add your own voltage setting for the best OC regarding stability and heat. You will see you have it set to Auto in your pirst BIOS screen shot...Offset Voltage = Auto that should be manual and then you set your own increments until stability.

 

The best way to go about this is to run the ASUS Ai Suite 3 OC utility and let it do its thing with a default BIOS configuration, this way you will see what is your suggested limit and how much you can adjust on your own with manual adjustments.

will try that as well and report back 

 

thanks again

after so many hours of testing and a lot of BSD's still, can't find a stable OC with adaptive voltage ...

 

I am now overclocked with these settings:

1-core clock 4.8Ghz

2-xmp profile 3200Mhz

3-core cache 43

4-LLC level 5

5-manual voltage 1.30V

 

very stable with every game 3+ hours and benchmarks 

temps max reached 80c on one core
