Skylake HWP Enable

Did you use customer ssdt generated by Piker script, if so, need merge PM ssdt.aml + ssdt-cf.aml, can you upload your modified macbook 9,1 plist, need verify frequency vector, XCPM and HWP settings.

Use boot arg -cpufoff to disable CPUFriend, re-create ssdt_cf.aml (only use one set of frequency vector table) test again.

Or, try previous attached CPUFriendDataProvider.kext (also work with 17C60C), need ssdt-tiny.aml, I remember the idle settings is 500 MHz, should work with your configuration.

Edit: or re-create ssdt_cf.aml with
attached edited mb91.plist, only change low idle from 1300 to 500 MHz and use 3100 frequency vector table.

First of all, I'd like to say a huge thank you for this guide.

There's absolutely something I'm doing wrong because I get frequency at the top all the time. (see pictures)
CPU is i7 6700k OCed 4.5ghz

Code:

Here's my settings ;
HWP value : 0x20002D01
HWP enable [x]
Use ARTFrequency [x]

boot arguments
-xcpm
dart=0

Did anyone went in the same situation and have an idea on how to solve it?

Thanks a lot and shoutout to everyone

From 10.12.x up, when Clover HWPEnabler is checked and XCPM is on then idle frequency will stick at the highest level, in order to make Clover HWPEanbler function properly need completely disable XCPM.

For Clover HWPEnabler user who willing give-up XCPM control, use FakeCPUID 0x0306a0 and add NullCPUPowerManagement.kext to Clover kext folder, XCPM will be completely disabled.

Others, use X86PlatformPluginInjector or CPUFriend injection method to enable HWP feature, a tiny ssd.aml (plugintype=1) is required.

Thanks a lot for the fast answer shuhung I did everything you mentioned and it works !!
Here's my result of running Cinebench on High Sierra. You can see the steady 4.5 when needed. I left the HWP value blank.
However, 20 watts on idle seems like a lot for i7 6700k? Is it? Any idea why? If not, it's not a big deal.

My CPU Frequency seems to get stuck according to "Intel Power Gadget" when I first boot my rig (see Screen Shot 1). Strangely after I put the rig to sleep and wake it up things look normal (see Screen Shot 2). Looking at the "Utilization" and "Temperature" from Screen shot 1, I don't think the CPU is really idling at max freq as the fans are at low rpm.

Any idea what could be causing this? Never noticed this behavior in 10.12.6. I recently updated to 10.13.3, running old lag free NVidia drivers. I can supply more info if it will help. Any thoughts?
