I notice a hashrate drop to below 6mh/s and rise back again with xI=65.
Drop to xI=64 (6274kh/s) and is not dropping anymore.(10kh/s or so)
Interesting. I've noticed that xI:64 is a slight increase in performance on x11; but absolutely no increase in performance on x13/x14/x15.
Sticking with xI: 50 still provides 4M solid on 290X on x15. I wanna see if we can get 4.1 somehow. I'm still stuck at WU: .056/m maximum on x15. Would be nice to increase it by .001-.003
