Yes I can solo that way, but pool mining doesn't seem to work at all. In previous posts, there are reports of a "diamond" kernel fixing things. I believe this is the source, just need a windows binary :/ https://github.com/danbi/sph-sgminer
Unfortunately, the author has abandoned sph-sgminer, this is why he did not integrated my Diamond kernel modifications back. Hopefully, someone will take over that project. There was a post earlier in this thread with link to Windows binary with diamond kernel.
In any case, hope to have soon an "official" build for Windows, too.
