Yeah I'm a little confused myself, I changed some of my settings, from a thread concurrency of 21792 to 8960 on an AMD 7950 and my hash rate went from 500Khash/s to 150Khash/s... However my Accepted shares went through the roof, in a span of one hour with my dual cards running a grand total of 200Khash/s I've gotten just about 18,000 accepted shares, meanwhile before I would be lucky to get 1000 accepted shares in 6 hours!

 Something is wonky!
