[SOLVED] What to do with C-states?

[mricsi97]

Hey! I've been trying to overlock my i5-6600K for a few days now. This is my first time overclocking anything, I'm slowly learning how stuff work and what is what. First I tried with fixed Vcore, found a somewhat stable spot at 4300GHz at 1.3V, but I was annoyed by the voltage being maxed out when idle. Since I have no "adaptive voltage" option in my BIOS (at least I couldn't find it), I started looking for an alternative, and found out setting Vcore with offset wasn't different only in how I input the number, but now the voltage went down when I was idle to around 0.88V.

Now my question is about C-states. There are 3 options for every C-state (C1E, C3, C6, C7, Package) in my BIOS: Auto, Enabled, Disabled. Here are the recordings of the first few minutes after booting and staying idle on all 3 settings. Why isn't there a noticable difference between Enabled and Disabled? I expected Enabled to be something like Auto. I expected Auto to make the system decide whether it is Disabled or Enabled, but those both give different results. I mostly use the PC for gaming. Which setting would be optimal for me?

Some specs:
CPU:Intel Core i5-6600K
CPU Cooler: ID-COOLING SE-214
Motherboard: ASRock Z170 Pro4S
GPU: MSI GTX 1080 TI GAMING TRIO
OS: Win 10 1903

It's low power mode for when you're not using your cpu. If you're over clocking you're going to want to turn it off unless you're using an adaptive voltage.

Turn it off and set power mode in windows to performance.

hey there , Asus X Hero Z-370 / 8700k @ 5.1 ghz here
my bios has 6 over clocking profiles and i have "adaptive + c states on" and "manual vcore c staes off " profiles

if i use c states values left default and turn c states on it works fine , long as so windows power plan is set to "balanced" then cpu can down clock/down volt .
-8700k @5.0 ghz profile adaptive @ 1.28v . c staes on avx offset =0 , power plan "balanced"
avast anti virus has a game mode when it notices a game ,it sets windows focus assist on and max power plan for me so i canm just leave windows to balanced its pretty cool.

my 5.1 ghz @ manual vcore of 1.34v i set c states off and intel speed step off .
