Nope, the system is unusable after Plymouth tries to start. Even with 1.3GHz. Looks like it's a dpm error, as on Windows the card is really stable. with those values, even if it's a bit overclocked.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
