I have improved the conf, i'm on 400 Kh/s now.
btw you should really mine x11 or scryptn on gpu
Yeah, indeed.
I hate to point you toward other pools, but clevermining doesn't offer these algos, and scrypt GPU mining is like running a very expensive space heater.
Check out Coinsolver, a smaller pool which supports scrypt-n and x11, which has short tutorials.
