So what am I doing wrong? I downloaded the pre-compiled binaries for windows yesterday. I have tried them on two machines (both with win7 64).
Once machine has 2 Radeon HD 5770s (not in crossfire) and I am getting 0 K/hash/s not matter which GPU I try to select (although from the output it appears to only be finding one GPU anyway)

I get similar output with opencl on the other machine which has an Nvidia 8800gts in it. When trying the CUDA option on that machine I get better results. However with the default optionsit was getting about 1000khash/s which seemed a little low. With tweaking (I now have the gpugrid set to 512) it is now getting between 10000 and 15000. Is that still too low?
Thanks for this tool. I look forward to getting it to work.
