Quick Guide to Generate a SSDT for CPU Power Management

d3k1d said:
Just tried to test the Power Management on my X99 / 5820k built.
Followed the instructions but after this ...
Code: 
[COLOR=#000000]kextload ~/Desktop/AppleIntelInfo.kext[/COLOR]

The machine immediately rebooted...
Any ideas what happened or what's the problem? :(

Same here. Never been able to find out whether it works or not...

SO today i have generatet a ssdt with the above script.

Here are two pics. The first is bevor the patch .

What you guys think about it ?

The first one looks better because it goes up to 40. The second only goes to 39. There should be a 41 if that's the turbo frequency. Did you run a CPU benchmark after loading the kext and before dumping the output? Also, try quitting every APP and close every window to see if it will idle to 8 instead of 10. I would use a benchmark to see which is faster, with or without the SSDT.
 
WORKED GREAT ... my sandy bridge hacintosh became very stable. Sleep related issues and no audio after sleep was fixed !!
Thank you for support....

try kextutil instead of kextload (as per instructions in the op).

It might dump more info, guy that got the error. And guy from the reboot, did you try googling that? I dunno really, would have freaked my **** out if my machine had done that lol

mine looks like:

edit: after testing this a bit, I noticed it goes up to x42 sometimes, but vast majority of the time it sits on x8 or x40. I look the frequency in hardware monitor. Also had a sleepwake failure tonight, not sure if related. I'm still not satisfied with the power management bc I want to see something else other than x8 or x40...

I tried this and all went smooth but my computer still will not go into deep sleep.
Also, now I get a screen flicker or blink about every 2 to 4 minutes. The blink is similar but not the same as the Screen Flash option in the Accessbility Pref Pane.
Could this revision to my system cause this?

Does it make any sence to do a SSDT for new Kalby lake Processor? Or it better to waite oficcial apple support?

Tried kextutil as well. Same error. Maybe it has a problem with the X99 platform...? Not sure.

For newer CPUs, you need to use the beta branch.
I wrote about it in my laptop PM guide: https://www.tonymacx86.com/threads/guide-native-power-management-for-laptops.175801/
