Hello guys.
I have my setup for 2 years and I will upgrade my GPU to an 1070 (provably MSI) and today I want to OC for the first time my cpu... I have a good cooling for that and a nice case so the airflow is really good (see pc spects in signature).

I want to oc my I7 to 4.7 or 4.8 depends how good my chip will be. I saw many oc guides but I still confused by one question.
In normal mode my cpu goes down to 0.8Hz in idle so I save power and my temps are really low. I want to know if it is possible to OC my cpu but maintain the "dinamyc" clock. So basically I want reseach the 4.7 or 4.8 when gamming or doing video editing or rendering code but go to 0.8 to 4.0 when browsing or doing other stuff.

Someone can tell me if that is possible or I will OC my cpu to 4.7 or 4.8 and it will be always in that clock?

Thx for answers!

BTW, i found this article that should be perfect for you. Take a look at it mate, and good luck on that OC :)

When you are doing the several steps for you OC, you should have you C-states off. C-states are the "configuration options" that automatically bring your CPU clock down when it is not needed (in order to save energy).

After you manage a good OC, and all is stable, you just need to turn the C-states back on, and that will make the CPU clock come down on idle, or when the CPU is on low load.

Thx for your answer... the c-states is disabled on bios menu or bios oc settings?

It usually is turned on/off on the BIOS settings (all OC options should be controlled there. I don't advise using software to change clocks and voltages)
