Hi Arlind! I am getting 29MH/s out of each card. I did my own BIOS mod which was simply copying the 1750 strap entry to the 2000 memory strap entry. The overclock is taking the memory from 2000MHz to 2060MHz, which is pretty conservative.
I keep my fans on 80%. Running Claymore v10 with AMD blockchain drivers. I am thinking about OCing the memory to 2075 soon to battle the increasing difficulty curve. Good luck and let me know if you have any issues.
