It's all about memory clock - setting a value higher than 1.2GHz (in a quirk) makes the system hang after Plymouth/before display server start. So, to my mind we have to do something with DPM/PowerPlay code or make some userspace overclock support, as there's no other way right now. By the way, is there such a tool that allows to overclock memory of the card? And yep, with its standard VBios card works with 1050MHz/1.2GHz (core/memory) clocks. I'm using those SMC patches + new firmware. Maybe they should be sent upstream, even to add that new firmware files and code to use them?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
