Markino76 Posted February 29, 2012 Share Posted February 29, 2012 Hi guys, sorry for the stupid questions but how can I verify that SpeedStep is really working well? Link to comment Share on other sites More sharing options...
Markino76 Posted March 5, 2012 Author Share Posted March 5, 2012 Hi guys, I've tryed to use MSRTools but after install the pkg I can not see anything on MSRTools screen... after the "Initialize...' message it becomes all gray with no info. Is there another way to understand if the Speedstep is woking? cmd line will be fine too... Link to comment Share on other sites More sharing options...
Gringo Vermelho Posted March 5, 2012 Share Posted March 5, 2012 You can find this information in the threads about native speed stepping. Here's one: http://www.insanelymac.com/forum/index.php?showtopic=225766 Link to comment Share on other sites More sharing options...

Markino76 Posted March 6, 2012 Author Share Posted March 6, 2012 Still can't find a way in order to show the instant cpu freq. I've tryed MSR Tools booting my netbook with arch=i386 but still no info on MSR Tools Windows. I saw that both with arch=i386 and booting without option in the SW info the 64bit option is "NO".

Gringo Vermelho Posted March 6, 2012 Share Posted March 6, 2012 You can see your power states in IORegistryExplorer (P- and C-states), how to do that is shown with screenshots in several posts in the topic I linked to. Use a temperature monitoring utility to verify that they are working. I am not familiar with any utility that actually shows your CPU clock in real time as it changes. AFAIK MSR Tools required you to install a low level driver for it to work at all, otherwise it would show a blank window like you say. I can no longer remember if MSR Tools only worked with the Voodoo Kernel or if it will actually work with the Vanilla kernel as well. Link to comment Share on other sites More sharing options...

ohump Posted August 16, 2013 Share Posted August 16, 2013 FYI. There is a new multi-os application and api from Intel that shows processor speed and current consumption. http://software.intel.com/en-us/articles/intel-power-gadget/ They also have a mac cpuid program -- that just displays info about your cpu. On i5 it doesn't display current speed. http://software.intel.com/en-us/articles/download-maccpuid 1 Link to comment Share on other sites More sharing options...
