Crank yoiur power down to 65-70 and see how stability goes. Increase by 5% until stable
Thank you for reply. If I lower down my power to 50% it works fine and stable but get low H/s then currently mining Mona coin lyra2rev2 algo on 100 pwr + 200 core + 700 memory getting 44-46 MH/s.
it depends on your vga memory vendor install gpuz and check if your memory vendor is samsung or hynix or micron if you have samsung +150 core +600 memory if you have hynix +150 core +100 memory if you have micron +150 core +400 memory
Thank you for suggestion currently my settings are 100% Power , +200 core and +700 Memory
