Now I tried to use first 950mV and then even 1000mV for P0 core V - P3 core V others are little bit higher. Same problem again. Next I have tried to lower MEM clock from 1000MHz to 945 MHz and still same problem. Again the problem was solved when I remove "PP_PhmSoftPowerPlayTable" instance from GPU 0004 with regedit.

I don't know what is wrong there or do I have bad luck in silicon lottery 

I use xmr-stak-amd with 2016/1600 intensity.
