Hey, Ive been having quite a dilemma for a while now, I have a Radeon HD 7770 Ghz edition and Ive been trying to mine with it. I know the amount of coins I mine will be very little but I'm playing the long game.
Okay so heres the issue, I'm running CGMINER 3.7.2 (I have tried numerous other versions and had the same issue) and I have my intensity set to 11, Ive tried other numbers aswell.

If I have missed any information you need feel free to ask

Hope you can help.
