Quick Guide to Generate a SSDT for CPU Power Management

I've also downloaded the latest AppleIntelInfo.kext and get the following information if it helps:

According to that output, you have lots of p-states, so I think you were successful.
In my Broadwell-E system, I only have one p-state still. How are you booting? Any fakecpuid?

I don't think the output from AppleIntelInfo.kext is sufficient. It doesn't show how much time is spent in each state. See my posts #103 and #105. How does the differences between my 2 outputs explain the difference in performance? I don't think it does unless I'm missing something.

I haven't been able to make my SSDT at all, so the output is whats already running

Also the Max turbo Frequency is 3.8Ghz on this chip, so it's definitely not right

this is what i'm running

Hi all, Piker Alpha told me to
Are you using this update of AppleIntelInfo.kext? That one works perfectly fine here.

And all that you really need is: ./ssdtPRGen.sh -turbo 4000

Either that or any other higher turbo value that you use in the BIOS for when you OC your setup.

What's that about: "But still the same error"? What error are you referring to?

So my new AppleIntelInfo.kext output now looks like this:

So it looks like i've "lost" some CPU P-States and they've all changed:

Is it full speedstep? also i wonderwhy can't check speedstep with method using Console app with AppleIntelCPUPowerManagementInfo.kext?

Forgot, i'm using Sierra. Maybe cause is AppleIntelCPUPowerManagementInfo.kext not support Sierra yet,right??

hi all
i created ssdt using this guide and it went well but I am unsure if its working fine and is there any clover changes need to done I have P states and C states enabled and here is the output with a warning Warning: 'cpu-type' may be set improperly (0x0705 instead of 0x0905)

Any suggestions on getting this to work with Broadwell-E? I have a 6950x and it only shows one P-State. I ran Pike's script and installed the SSDT, but it did not help. I'm using fakecpuid=0x0306F2 to make this system boot. Intel Power Gadget shows my CPU flatlined at 4GHz all the time.

Ya, also waiting for Broadwell-E. 1 C and 3 P-states atm... (6850K)
Also the ssdtPRGen -show flag does not show squat for some reason (-s gives error)...
 
i have broadwell-e, i'm pretty sure i have states working ok, but have some error messages in clover log that i'm not sure about
