Disabling C States in LOQ huge improvement on stuttering and micro stutters but afraid of frying it if I use it on the long run

[DanSymonds]

Am I torturing or gonna damage my laptop's CPU in long term if I continue using it this way. Cause I disabled it in Lenovo's Advance BIOS and tried to use it in games it cause significant improvement on performance though, but I'm afraid if use it for long time my CPU would be fried

your active use drain will be nasty, C-States allows the processor to idle or even go deeper sleeps to save some juice and prevent excessive heating

nope no measurable impact

When you disable the C states in the BIOS, it usually leaves two C states still available. The CPU will be in the C0 state when it is actively working on a task. CPU cores will enter the C1 state when they have nothing to do. This is not going to hurt anything.

If ThrottleStop reports C0% = 100% even when idle at the desktop, that means that the C1 state has been disabled too. This will cause much higher power consumption and should be avoided. This is rarely the case when using the BIOS to disable the C states.

When not playing games you should still be able to use ThrottleStop to toggle the C1E state on or off. This helps save power when the deeper C states like core C7 have been disabled. C1E does not save as much power as C7 but it is not too bad.

The only negative is the non K CPUs will not be able to use the maximum turbo ratios when it is lightly loaded. Disabling the C states will give you reduced latency but a slower CPU when it is lightly loaded. For some applications like games, that trade off is just fine.
