Thinking on disabling C-State on my PC. I use my rig mainly for gaming. I did google it. But can't find a lot about. Other then it states that is disables power savings. What are the pros and cons doing it. My full specs are listed. Thanks.

You must bear in mind that turning off the C State will prevent, for example, that your computer can enter Windows sleep or hibernation mode, since it will not be able to turn off the processor among other things.

I would not change it personally - sleep mode is too useful.

I take the view that you should only change such settings if you really understand them. A little knowledge can be dangerous.

That is incorrect. C-states have nothing to do with sleep or hibernate.

C-states are low power states of idle cores while the system is running. Sleep and Hibernate are system level states where the system state is saved and the system is not running. Try it, then come back and correct.
