Hi all,
I recently stumbled over this OC guide for ASRock motherboards with Sandy/Ivy-Bridge CPUs.
It helped me chose the right settings and to reduce max Vcore at same freq under full load from 1.360v to 1.280v, which is not all that insignificant.

It goes very in-depth and every option is explained. Some options werent available on my Mobo, but overall ASRock mobos generally have common/similar options.
