For the impatient, here is HVC cgminer version that works on 1gh:
https://github.com/reorder/cgminer_skeinIt currently only works with GCN cards (or so I believe). No binaries are available as it is a WIP, and
I will not provide support for this version.
Please configure with './autogen.sh --enable-heavy --enable-opencl' and run with '--heavy --vote 1024' (or your preferred vote). Best intensity setting seems to be 3 for all cards, but you may have luck with higher values.
I'm getting 1.7Mh/s on my card. But I don't seem to be finding shares any faster than a crappy Azure VM that gets 80Kh/s, despite the Mh/s being reported by cgminer. Are you actually finding shares faster, or is there something odd about the speed reported by cgminer?
