Windows 10: Power plan CPU frequency settings affect only E-cores, not P-cores, is it a bug?

I have DELL XPS 9520, Inte 12700H CPU, turbo boost is off.Windows 11 21H2 22000.1335If I change Maximum Processor state parameter of power plan, it affects only E-cores.I want to adjust both E and P-cores, how to do that?Please see attached screenshot illustrating the problem.

SOLVED: Power plan not working

Hello,

I have an Intel i5-12600K which I have overclocked to 5.2ghz on the P-cores, and 4.0ghz on the E-cores.
When using the "Ultimate Performance" power plan, I set the "Minimum processor state" to 5% (I have also tried different values here), and the "Maximum processor state" to 100% but the CPU constantly bounces between the turbo-boost speed of 4.9ghz and the overclocked speed of 5.2ghz, not dropping below.

If I use the "Balanced" power plan, the CPU frequency drops to the value it is supposed to. I can see the frequency bouncing between it's low rate of just a few hundred megahertz, and the high rate of the turbo-boost frequency of 4.9ghz. However, the balanced plan does not use the overclocked frequency. It tops out at 4.9ghz which is the turbo-boost standard frequency.

Ideally, I want to use the "Ultimate performance" and have the CPU frequency able to drop to it's 5% value when it needs to, and top out at the overclocked rate of 5.2ghz, but it does not do this. Why is the "Ultimate performance" frequency not dropping despite the minimum processor state being set to 5%?

For the sake of testing, I also set the maximum processor state to 50%, and even 20% using the Ultimate performance plan, and the CPU frequency still did not get any lower than 4.9ghz.

It seems that it isn't using the minimum processor state value at all on the Ultimate performance plan, and isn't detecting the overclock value on the balanced plan.

Is there anything else I can try?
I am running Windows 11 with the latest updates by the way.

Thanks in advance

 

Intel Core i7-4770K - healthy core speed



Is my i7-4770K running at higher core speed than it should? The core speed is usually around 3.9 GHz according to CPU-Z. I expected it to stay close to the processor's base frequency (3.5 GHz) and not always at max turbo frequency (3.9 GHz).

I haven't overclocked. Windows 10 power plan is set to high performance.

 

amd cpu"s all cores locked to one frequence phenom 2, A8 3500m amd 9370 8 core, 9500

amd cpu"s all cores locked to one frequence phenom 2, A8 3500m 9370 8 core

Before 1607 all cores worked at a different per core clock from lowest to highest .

Now all cores run identical to one frequency.

Can understand the 9500 has only 1.1 to 2.2 so the cpu has little headroom.

but the 1055t 800 mhz to 2.8 turbo 3.3, a8 3500 800 mhz to 2.4 ghz,

9370 1.4 ghz to 4.4 ghz turbo 4.7.

The later three are all locked to one freq. as if they are one cpu.

The 9370 has never been stable at a tubro of 4.7 4.4 max was the highest it could get to.

I use core temp, cpuz, speccy to verify

Win10 1607 rs1, rs2 have the same issue on amd cpu cores all work at same frequency, a89500m, 9500, t1005 amd 9370. All cpu's work at the same clock frequency with different loads % Past operating system from Microsoft did not have this issue. 4, 6 and 8
cores should work independent of each other depending on cpu heat, workload and voltage. I do not know if this is the same for other cpu's made from intel but would like to know if it is an issue.

Cpu core clock should not be spread across every core, it makes the cpu work more when not needed. My guess here is to keep pc cpu's, phones and tablets working in the same fashion. No wonder we have stability issues on win10.

Would like to see a real Microsoft hardware engineer give some feedback on this.

Would like to know if anyone else is seeing this issue and if intel cpu's have the same problem.
