Hi Everyone:

I'm mining with a 6670 and a 5770. 6670 works great with cgminer, but considerably slower than 5770.

But I can't get 5770 working with cgminer con windows 7 64 bits. cgminer just have a forced close when it tries to start mining with the gpu. I prefer cgminer vs bitminter software as cgminer has better over/under clocking options, and allows me to get almos 15% more power in the 6670.

Any ideas that can help me to run cgminer on the 5770?
