Hey I bought a new 13700k too. I couldn't figure out why my core clock speeds (P-core 5.3 and E-core 4.2) are always constant in this processor. Can someone help me? How can I fix it? I don't want the core clock to go up when I'm not taking action.When I save in power mode, the core clock speeds drop. View attachment 2585702

Which motherboard?

Asus z690 plus D4

Assuming that this is your manual:

PRIME_PROART_TUF_GAMING_Intel_600_Series_BIOS_EM_WEB_EN.pdf (asus.com)

It looks like the relevant settings start on page 17 -- screen shots from my build below; we don't have the same board, but the BIOS settings appear to be mostly similar:

CPU power management is working well here.

Thank you for the answer stahlhart. I'm sorry to forget to say my mobo's model. yes it is tuf z690 d4.

I think I need to enable c-state. It is currently on auto.
Also, what should I do about Package c state limit? you defined it as 8.
What difference would it make if I set this value to 6.7 or 8?

To be honest, I just chose 8 arbitrarily after seeing in in an overclocking guide in my travels that I can no longer remember now. There are folks here who know way more about this than I do, but I think C1E is about where you get started with the adaptive power management behavior.

I'm not sure if C6, C7 or C8 difference would have any bearing on performance -- I just more or less set it to 8 and forgot about it, because everything seems to be working correctly here and I'm not noticing any degradation in performance.
