Hello 'Shmerl', can you (and the other) please recheck with 'auto', too? I think we have the 'same' problem with Polaris, too. If one set low/high it is set @fixed frequency and NOT @ the 'flickering' 'auto' mode. I can't test the 'suspend / resume' cycle 'cause my server/workstation do NOT work reliable on it. But power consumption is definitely to high on Polaris, too. @Alex: What do you think about this?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
