x1a0 Posted February 14, 2012 Share Posted February 14, 2012 Hi, I applied the SpeedStep patch for 10.7.3 and it works fine. However with MSRDumper I can see there are only 2 steps are used: Feb 15 00:17:57 Zhangs-MacPro kernel[0]: MSRDumper CoreMulti(43) Feb 15 00:17:57 Zhangs-MacPro kernel[0]: MSRDumper PStatesReached: 16 43 Feb 15 00:17:57 Zhangs-MacPro kernel[0]: MSRDumper CoreMulti(16) Feb 15 00:17:57 Zhangs-MacPro kernel[0]: MSRDumper PStatesReached: 16 43 Also in the boot process I can see: ACPI CPUs not found: C-States not generated !!! ACPI CPUs not found: P-States not generated !!! I know this is not a problem about SpeedStep patch. From what I've read I guess I need to put some SSDT.aml file or DSDT.aml file under /Extra. However I don't know how to get them... Thanks for helping! Link to comment Share on other sites More sharing options...
The Edge3000 Posted February 14, 2012 Share Posted February 14, 2012 This is posted in the wrong sub-forum, but I have the same problem. However, when I am in Windows, CPU-Z seems to jump between x19 and x43 as well (although other tools besides CPU-Z sometimes read inbetween). I do not use the speedstep patch, but chameleon outputs that it created p-states (and the SSDT I can extract while booted into OS X shows multiple p-sates), but the debugger will only show the minimum and maximum sates being used, even after an hour or so of running.

buoo Posted February 14, 2012 Share Posted February 14, 2012 It's not the right place to post problems. moved Link to comment Share on other sites More sharing options...
slave-zeo Posted February 22, 2012 Share Posted February 22, 2012 I get the same, but it doesn't really bother me. I'm just glad to be able to use the max speed on my CPU. I get 16 and 45 in Lion and Mt. Lion. Link to comment Share on other sites More sharing options...
