Anyone optimized sgminer kernel for ATI ?
The official one is already pretty optimized. Has some issues with chips before Hawaii though.
yeah, tried it on a 270x and it hashes at approx 700khs, but no shares found.
But even if shares were found,well.. 700khs.. ?

W0lf has some public kernels for cubehash, fugue, skein, don't know if it would make some speedup .
