So I finally got Cudaminer working with CUDA 5.5 on my GTX 560, but it's reporting crazy high hashrates, in the range of 100,000-500,000 kh/s mining Scrypt.
On top of that, the pool I'm mining with to test it out only received two shares from me 10 minutes, and told me I was ranging from 0-3 kh/s.

Any suggestions on what I'm doing wrong?
