Hi Christian, me again. dunno if im barking up the wrong tree here but if i reduce the amount of cuda threads, i.e:

'case 16: fermi_scrypt_core_kernelA<16><<< grid, threads, 0, stream >>>(d_idata); break;'

Say i set threads to  say 256 (<512). theres a massive increase in speed... But quite a few errors.

Why the errors?

Cuda is still new to me....
