EDIT:
I have found a BUG in the new sgminer whit Lyra2REv2 Support for AMD Cards, whit Catalyst 14.9 or higher, i have only HW`errors when i start mining...can confirm that someone?!?
Whit 14.4 or lower no Prob.
which cards ?
I will have a look
AMD 5970 with catalyst 13.111 have only HW errors
can you check that the old lyra (Lyra2RE) is working within that version ?
you should get boo instead of hw error
