iDogma Posted February 24, 2010 Share Posted February 24, 2010 Hello mates! I got performance issues after enabling speedstep (MacPro3,1 model). Temperature is about 38-40, but interface is working worse (effects like hiding or opening windows are not smooth), xbench quartz score is about 150-160, gl score - 86. video fired up using dsdt. any ideas why so low performance? p.s. without speedstep my video works perfect, smoothly and without any lags Link to comment Share on other sites More sharing options...
pirloui Posted February 25, 2010 Share Posted February 25, 2010 Maybe it's stuck at the lowest frequency, you can check with cpu-x. http://netkas.org/?p=72 Link to comment Share on other sites More sharing options...
bbeepp Posted February 25, 2010 Share Posted February 25, 2010 ...xbench quartz score is about 150-160, gl score - 86.... Seems like your graphic card is not working properly. On mine system Quartz score is 298 and OpenGl score is 160. Link to comment Share on other sites More sharing options...
iDogma Posted February 26, 2010 Author Share Posted February 26, 2010 But without speedstep my quartz is about 220-230 points, opengl about 100-110. Much better, when without speedstep. Any ideas, why it is? Maybe it somehow connected with my low-power psu (500v, i heared this is a minimal bound for gtx260 and q6600). But on Windows i don't get any troubles, games and other stuff works fine. Link to comment Share on other sites More sharing options...
gatsu_1981 Posted March 19, 2010 Share Posted March 19, 2010 Mate! I got your very same issue when I was finally able to get speedstep working on my overclocked Q6600. And I resolved it! You should make your hands dirty inside DSDT however: http://www.insanelymac.com/forum/index.php...&start=1330 Link to comment Share on other sites More sharing options...
