That's not one at a time
adaptive cache does not work, this is a limitation of the CPU architecture. If you want to make use of the power saving features available then adaptive is the preferred method over manual. If these things do not concern you then manual is fine. C-states can be left at their default values for both methods, the board is able to handle these things.
The adaptive vcore function works only on 100 strap. Simply enter the total voltage you require into the additional turbo voltage field. (E.G if wanting 1.2v, enter 1.2)
If still unsure it's probably best to contact the support for your region
