i5 7600k underclocking at idle.

[klaudmjj]

I have my i5 7600k overclocked to 4.7ghz at 1.2v. Idles at around 30-35c. My cooler is the pure rock slim.
When it's at idle, it underclocks it self to like 1.06ghz at fluctuates.
What setting do I change it so it's a constant 4.7ghz? And will there be any difference in performance?
My motherboard is the Asrock z170 extreme 4.

For windows 10, go to settings, system, power and sleep, additional power settings, select show additional plans, select high performance.

Intel has technology that when the cpu is on idle or does not need all the processing power will use less voltage and less heat. Witch prolong the life of your pc and cost less electricity. All in all this is normal and no problem with pc

see wiki https://en.wikipedia.org/wiki/SpeedStep

If you are looking at the speed in task manager, then it is wrong. But in any case, it's good to downclock when idle and doesn't affect performance. Keep it on. Let it do its thing.

Just leave the settings alone. If it clocks to set overclock under load then there won't be any issues. If you are still worried about it try disabling the 'core C6 state' in your BIOS. Basically allows the CPU to under volt itself and even turn itself off.

You need to turn the CPU ratio mode from 'Dynamic' to 'Fixed' in your Bios settings. In dynamic mode it will automatically lower the ratio to conserve power. I'm using an MSI z270 krait board so your settings may be names slightly different.

Also, if it not off automatically turn off 'Intel turbo boost'. As your clocking above the standard 4.2ghz it's not required.

I'm using a 7600k @ (fixed) 4.2ghz myself with a Corsair H75 and my idle temps are 40C avg. With your cooler your idle temps will likely increase a bit.

I'll add that multiple online sources show that average computing power for gaming is lower when dynamic ratio is activated, how noticeable this is I don't know.

Edit: Turns out my H75 pump was on the brink, was replaced under warranty. Sold that and got a H80i v2 and now idle is 25c to 28c.
