mine (spare one) normally @805 starving due to some crashes @850 starving - it needs lv to work well. Lv goes up to 1100 without problem when a little boost is needed - QBW for fast OC changes on the fly. And yes, it i true than anything over 1000 feels smooth and make go back to original a (small) pain. From PR1.3 afterwards I am really happy with my N900.
