i7 8700k Constantly at max clock speed.

[kieranfr]

Hey guys I got an i7 8700k a little bit ago and I can't get it to decrease the clock speed when not under a high load, It constantly runs at 4.4-4.7 Ghz. I am probably just missing some setting in the BIOS knowing me. When I disable Turbo boost it just stays at 3.7Ghz.

All I want is for the CPU to go back to it's base clock speed when not under load and then ramp up when needed. Any help on resolving this issue would be appreciated, all of the following images were taken right after booting up my PC and leaving it idle. I recently updated my BIOS and reset the settings.

My motherboard is the MSI Z370 SLI PLUS.

Set power options in Windows. Maximum performance will keep your chip at full clocks if it's set.

Misc setting, you have eist disabled. It needs to be enabled iirc. 4th screen shot showing bios.

After changing the Windows power settings to Balanced and restarting my PC nothing has changed.

After enabling that this is happening, not sure if it's normal or not.

Yes, fixed. Min is now 800mhz. You get spikes like that even when idle as its not fully idle as such. If you want to be fully sure, run a CPU benchmark and the graph should look like your first image, once stopped, you should see a drop off.

This happened to me as well. Seems the power setting need creating manually. Now its going down to 800mhz.

Hi could you tell me what was the setting? Can't see the screen.

i'm on "normal" energy plan, oc to 4.8 and for what i see, my cpu is most time between 4.5 and 4.8

Thanks

Read the thread through rather than tagging on to the end and you'll see that @Drollic gave the solution.

Hm that does not help

Eist is enabled for me but don't know what iirc is
I have eist enabled and all c states i think

it does idle but i see it more often at 4800 than 800

"iirc" isn't a setting in the BIOS, it is just short for "If I Remember Correctly"

If you're seeing it idle, albeit briefly at 800Mhz, then everything is set correctly. It will only take a small load on the CPU for a second or less to increase the frequency.
