Sbrillo Posted May 9, 2015 Share Posted May 9, 2015 hi! i have problem with power management. Only 4 p-states are displayed (8 35,37,39) smbios definitions are from imac 14,2 when i generated ssdt, put in clover/ACPI/patched folder, add drop oem true in config.plist and reboot, i'm stuck at apple logo. tried to boot with -v and stuck at loading realtek ethernet. why? This is a fresh install of Yosemite pc specs are in signature Link to comment Share on other sites More sharing options...

Allan Posted May 9, 2015 Share Posted May 9, 2015 Ok. For Haswell, all you need is here: [GUIDE] Patching the kernel for Haswell CPUs, XCPM early reboot And you don't need use SSDT generated by script. Just make sure that your config.plist is configured properly. Link to comment Share on other sites More sharing options...

Just make sure that your config.plist is configured properly. i have already kernelPM in config.plist. i've tried with ssdt, and without ssdt, but i have 4 states without ssdt and stuck at boot logo with it here is my config.plist if you want to take a look config.plist.zip Link to comment Share on other sites More sharing options...
MacUser2525 Posted May 10, 2015 Share Posted May 10, 2015 You are getting what you are supposed too those are all the states an iMac has so all you will see reported. Now if you install the HWMonitor program you will see or should at least like I see that it will report lower states being used. Link to comment Share on other sites More sharing options...
joe75 Posted May 10, 2015 Share Posted May 10, 2015 Some corrections are needed here.. The kernelPM command and guide linked here is for mobile haswells and doesn't pertain to 4690 at all.. You do need the generated SSDT or at least the patches it provides to have x86platformshim load for proper PM in cpu and gpu.. Link to comment Share on other sites More sharing options...

I use only -xcpm and kernelPM, without SSDT generated by script. And the Power Management is ok: On IvyBridge and Haswell - Mobile/Desktop Link to comment Share on other sites More sharing options...
joe75 Posted May 10, 2015 Share Posted May 10, 2015 glad it works for you but technically you shouldn't need either of those for a desktop cpu that supports kernel power management Link to comment Share on other sites More sharing options...
