As the title suggest I am trying to find a good overclock for my 8700K on the ASRock Z370 Extreme board, I have found it stable at 5GHZ at around 1.28 vcore on fixed voltage LLC1 which I believe is the highest on this board. Main issue is I cannot for the life of me get it to drop vcore at idle & when using offset no matter what offset I use the max vcore seems to shoot up to 1.372 -1.392 but obviously I don't want it that high as it runs so much hotter and it should stable at much lower Voltages looking at the fixed voltage results.

Am I missing something with these new boards? It's been my first upgrade since Sandy Bridge where I used offset voltage and this worked well, I just don't understand why I can only use fixed voltage to lower voltage and why offset is putting it so high

Hi Mattmagoo44,

You should look into your BIOS for Intel SpeedStep Technologie (EIST) AND enable C-State.
Both combined will let frequency and voltage fluctuate depending on the load.

Instead of using Offset Voltage, you should look for Adaptative voltage, which let your IDLE voltage a bit lower than with offset.

Hi, thanks for the response.

I don't think my ASRock Z370 Extreme has the adaptive option unless I am missing it?

Is it possible to get the voltage to go down with the clock speeds at idle when using fixed voltage? I have managed to get it working on offset with the negative offset but it's not ideal tbh.
