Ok im try on ATI 5770 and dont work .
Im use --heavy --vote 512 -o stratum+tcp://hvcpool.1gh.com:5333 -u WALLET -p x .
The miner is beta and WIP, it does not work on anything but GCN cards yet, give it up.
I've compiled on Mac (6770HD) with the same result.

Also I cannot seem to get even --skein working. Always getting "Pool 0 JSON stratum auth failed: (unknown reason)". Any ideas why?
6770 is not GCN too, only 7xxx and R9 series are. However, release version will support older cards too.
