CPU Not Changing Speed During Idle?

[xXComputer_Nerd1625Xx]

I have a 4690k running at 4.4Ghz at 1.191 volts. The voltage is set to adaptive on my MSI Z97S-SLI Plus Mobo. Intel Speedstep is on too. The thing is, I used to have it running at 4.2Ghz at like 1.14 volts, and when idling the CPU would lower it's voltage and speed accordingly. But now it doesn't, when all I did was change the multiplier and core voltage. Is there any reason why my CPU is running at 4.4Ghz @ 1.191 volts 100% of the time now? What can I do to fix it?

Set min and max settings for your multipliers manually, and set the max voltage you want manually also. Then go and enable c-states and your frequency and voltage should move properly with cpu load %

Do I do this in the BIOS under OC Settings?

 

[sportsfanboy]

yes in bios, the c-states might be under cpu settings

But shouldn't Speedstep also be doing this?

the newer boards are a bit different. You need c-states to be enabled when overclocking or it wont work. If you weren't overclocking and you left stuff on auto then it would.

Turns out that windows wasn't letting the CPU back down from 100% speed, so I changed that setting and it works, albeit it only clocks down to 4.1Ghz :/ I couldn't find anything in the BIOS about min/max voltage/multiplier

what c-states did you enable? what other settings did you change from default?

I just changed C-States from auto to enabled, but left another c-state option on auto, I forget what it's called...I'm gonna screenshot the BIOS real quick

It doesn't have anything to do do with the fact that my current BIOS version is v1.0 while theres a v1.7 I can download does it?

try package c-state to manual and enable the states. I forget which once in particular I have set I'll have to look at my bios.

 

[sportsfanboy]

you should be able to set c3 c6 c7 etc, to enable, hopefully that works for you

I can't find a way to enable/disable specific c-states....only to set that "package limit"

I've got it fixed now, Thank you. It was actually on Windows side for whatever reason. I appreciate all the time taken for you to help me out.


If curious, I changed my power plan from the recommended on to something more useful to me. In the advanced options, there's a min/max CPU option and I had mine set to the same as the recommenced balanced plan (5% min). For whatever reason, switching it back to the balanced plan that came with windows allowed the CPU to underclock. So yeah.

no problem, glad it worked for ya
I know about power management settinigs, but thankyou 😉
