Here is the results for R9 390X. is it possible to get higher Hashrate with this graphic card ?

Claymre Dual Mining for ETH.
ETH only mode




30.467 - 30.804 Mh/s for ETH only mode.
Power: 341-348 Watt

28.139 - 29.635 Mh/s for ETH + 428.223 - 444.293 Mh/s for DCR
Power: 363-367 Watt

I cannot live, I cannot die, trapped in myself.
Hold my breath as I wish for death. Oh please god, help me !

Yeah you could get 33Mh or more with a 390X.
Push the core clock up and the voltage down and find the sweet spot. you will need to enable voltage control in Afterburner's settings because I see it's still disabled for you.

Yeah, the card is only slightly overclocked from the factory.

Below 80 is pretty good. make sure you are not reaching the 90s. reference 290s with the same core used to run at 94c but I won't recommend it.

Core clock 1200 Mhz is good. If I try to higher value, the system crashes and I have to restart the pc. I know it is important for mining. Now I see 34 Mh/s.

What is the core voltage for ?

If you can decrease the core voltage while maintaing the same hashrate do it. It will lower the heat and electricity consumption.
