It is OK.
Just look at your core clock. It is 1500Mh/s. You need 2000 to get normal speed.
You cant get 190 watts with such clocks. Only if you rise to 1,5v core voltage. But I dont think you need it.
smos sets its own powerlimit of 140w instead of 190. cards are hashing 45mh instead of 65. whith such wrong low powerlimit rigs crash also
