I think at the end it was the bat file setup. It might have been the max temp command that keep the power limit well below what was needed. Fixed that and set intensity to 29, although when the program runs regardless of setting it to 29 or 30 it only takes 28 as intensity, odd. Either way I'm mining happily at 4.7 Gh/s.
You should be careful with intensity, starting at 20, then increasing gradually in order to get the most comfortable one for your rig. Dont start at high intensity, which can lead to terrible crashed for your rig.
