The idle core frequencies are excessively high.

Hey everyone,
I'm trying out some overclocking on my new setup:
Gigabyte Z390 Gaming M
9900k (+ Kraken M22 cooler)
32GB Ram 3000
Currently I've configured it to 5Ghz clock ratio / Vcore to 1.325 / LLC Turbo / AVX 0 (I saw somewhere that the BIOS might be broken and should stay at 0 until updated)
When I check HWinfo in Windows 10 while idle, I see this:
Is it typical for cores to run at 5Ghz during idle in Windows?
Thanks for your help!

I'll wait for the next BIOS release. Gigabyte has a track record of unusual problems with their motherboards. From a purely hardware standpoint, Gigabyte produces excellent motherboards, but their UEFI implementation is a major concern.

I have the same thing with my i5-4670k:
Spoiler:
my clocks
I think the system can't control the frequency since turbo boost is disabled and we have overclocked our cpus
Also, there is an option in bios that allows to control voltage and clocks (CPU Ratio Mode). I believe I have it enabled (Dynamic), but it works at 4200 anyway. Try to check the option in your bios.

You might have turned off certain c states in the bios check.

It's a smart move to turn on C states, right? Keeping them off could damage the CPU?

Also, look at the Advanced Settings in Power Options
If it's set to 100% in Minimum, that's likely the cause. I just tried it and now I have variable clocks.

I believe this could be the solution! I attempted to activate the C states but the issue remained. I'm about to try again. Also, what minimum value should I select? 0? 10? 50? Thank you!

Choose Balanced plan rather than High Performance. It will establish the Minimum at 5%. Alternatively, you may adjust it to 5% or 10% manually.

Ensure C states are enabled and avoid using manual voltage. Opt for offset or adaptive voltage instead. Usually manual voltage doesn't affect CPU clock behavior, though some boards might.

Sorry to hear that. You've already tested many options and still see the same issue. Frequencies remain at 4.9 during idle. Reset BIOS settings and adjusted clocks, XMP, and C states, but nothing changed.
