I can see your core clock is 1380 Mhz but your mem clock is only 300. I don't know what you are mining but you should start with a clock of around 1150 and increase your mem clock. Start at 1800 and increase with small increments.

Ok nvm i see its running at 1900. What drivers are you using?

Have you set the GPU to Compute mode in the AMD Radeon Settings?
