Raveos OC issues.

Anyone use raveos? I'm having trouble with oc on it. I have 6×3060's, running nbminer, on 2miner pool through windows, and can get 144mh, with 864w constant. But in raveos, with the same oc settings, I'm getting 135mh, @1100w. I would very much like to use raveos, as the no pool fee is awesome, on top of being able to put my rig in a location out of my home. Any help would be awesome!
