I did not get these issues in fglrx or the windows drivers. I then happened to notice that the memory clock settings for the 'boot' power profile were incorrect, and were significantly higher than the card should support. The high & low power states appeared to be correct. Changing the boot values using the Radeon Bios editor (<a href="http://www.techpowerup.com/rbe/">http://www.techpowerup.com/rbe/</a>) fixed these problems for me.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
