For me your miner is way more stable than ewfb's. While ewfb's simply hangs in 24-48hrs period on Windows and even sooner under Ubuntu, yours working stable. If only I could figure out how to overclock under Linux on a headless rig...

EDIT: However, It disconnected today twice. Once it just said server disconnected (i'm using nanopool) and failed to restore the connection, despite internet was working flawelessly on all other devices in a household. Restart of the miner itself immediately fixed the issue. And the second time it started throwing some connection errors, and again everything else worked like a charm. Restart fixed it as well.
