Hello gang, A friend said to come here for some help.

I've done a new build, i7 13700KF, Asus AIO, Asus z790f, DDR5 5600, RTX4080.
My previous builds I have always had power plan on balanced mode, 5% min, 100% max, which did what it says. Now with this build on balanced power plan my CPU sits at full clocks at idle, 5.3ghz. The only way to get the cpu to downclock to idle is setting power plan to power saver mode.

Done a bit of reading, I see a lot about Asus multicore enhancement, changing the setting didn't change the idle speed. Speedstep, changing that setting did nothing too.

I am now stuck, I don't know what setting to change and I don't want to keep switching power plan from saver to balanced every time I start up a game.

Does anyone know what I should change ?

TIA
Aaron
 
Have you installed the chipset drivers and reset the power plan to defaults?

Relevant settings: speedstep, EIST, C states.

I assume you're sure nothing is using the CPU at all? Some apps can peg the CPU, even with minimal load.

You don't have any OC/auto-OC profiles enabled?

What about software, have you installed the Asus software? If you have I'd consider uninstalling it.

Yes, all the drivers are installed/updated, I reset the Balanced power plan to default and tried a power plan I created but no change.

Speedstep, i changed that and nothing happened.
EIST ? not sure what that is, internet says it's Speedstep so already tried that.
C state, i have not touched that. I have had a read about it, not sure if that should be changed.

I assumed asus would give me the correct bios settings, everything is at default in the bios apart from the XMP for my ram.

To what i can see, nothing is pegging my cpu

EIST & speedstep allow the CPU to dynamically clock up and down in steps, C states are idle states, each higher state (higher numbers are a deeper idle) gives it a bigger power-down mode. Some motherboards are very conservative with their C states because not all PSUs are comfortable with the CPU heavily powering down.

What monitoring software are you using to get the clocks? The monitoring software itself can sometimes be the culprit. On Ryzen, things like Discord and Steam can also prevent lower idle states.

I've also heard about motherboard software like armoury-crate & dragon centre causing problems.
 
I'm using HWmonitor and cpu-z.

Armoury crate, yes i use that and i have done for years, I've never had a problem with it. Yes it has a lot of processes running but all are running fine and the software is running fine too.

I use an ATX 3.0 psu too if that helps

I'm not saying it IS the problem, but I'd definitely try uninstalling it. This type of software have so many features nowadays, RGB, auto-overclocking, hardware monitoring, power profiles, automatic updates, their opportunity to interfere is pretty good.

The only other software I can think of that gets the CPU stuck is third party RGB software.
 
That's why I use it, most of my Pc is Asus, mobo, gpu, AIO, mouse and keyboard. I don't know if you use it but it is very convenient, every thing is in one place, firmware, updates, rgb, mouse dpi blah blah lol.
I don't want to uninstall it, I think it is something else.

When power plan is in Power Saver the cpu will idle to 1.1ghz btw.
 
I tried a different setting on the c state, changed from auto, doesn't say what auto is at so put it to enabled, reboot, still the same, clock at full speed. I guess i just have to switch between power plans

Done a bit of reading on my situation, people have it with Asrock and msi too.
