Gnaffel! It's working! poclbm is showing 308 Mhash/s per core without any tweaking. Seems I wasn't using the 'python' command and 'user=' Not pool mining yet, just testing. Throwing out some serious heat - 84C core after several minutes. The phoenix command still errors with 'failed to connect.' Is this how it's normally done; start poclbm and then phoenix?
Thanks; I sent you coin.
