Quick Guide to Generate a SSDT for CPU Power Management

[howmanyds]

Problem is 2 parts:

Part 1probably causing the second part of the problem) When I enter step 4 of OP guide, terminal says it doesn't like my sys def for my board:

bash-3.2# sudo ~/ssdtPRGen.sh

Part 2:
I continued with the OP guide, despite getting a weird message here, and found and copied over the ssmt.aml file. Then I receive the the previous quoted terminal response (4 posts up) when I try to verify: "/Volumes/Data/TOA/Desktop/AppleIntelInfo.kext failed to load - (libkern/kext) authentication failure (file ownership/permissions); check the system/kernel logs for errors or try kextutil(8)." This means I can't check functionality of ssdt.aml per the OP guide.

You're using wrong system Defintion. Use iMac 12,2 if you're using 10.11 or older. If you're using 10.12 then use iMac 13,2.

 

[howmanyds]

I'm on Sierra already, so it's either 13,2 or 14,2 that I've tried but they each give me the above problems.

 

[alessandrodl]

I tried to generate the SSDt for my i7-6700k with ssdtPRGen.sh but i have noticed that after the generation my CPU was always at max speed (from HWMonitor software)

instead if i delete the SSDT file the CPU works great, also overclockd to 4.4 Ghz, and in HWMonitor the CPU speed my vary from 1000 Mhz to 4400 Mhz.

I set up a iMac 17.1 model in clover

Why?

 

[dmeadows013]

Running into the same problem on Sierra with a iMac 14,2 (6770K, ASUS ROG HERO III)...
Getting both:
Warning: 'cpu-type' may be set improperly (0x0705 instead of 0x0905)

and:
Error: board-id [Mac-27ADBB7B4CEE8E61] not supported by Skylake – check SMBIOS data / use the -target option


I am overclocked to 4.6GHz

 

[slamjack]

Hi, please take a look

I noticed that my i5 4440 Haswell can start operating at maximum frequency for a long time beeing idle:


So I followed the guide and got my SSDT.aml (I got SSDT.aml-1,2,3,4 but I copy only SSDT.aml to
/Volumes/EFI/EFI/CLOVER/ACPI/patched/)

Here is the test, after patching, please tell me is it ok?
At first sight it became better, but frequency can jump high from time to time without any reason:



I did not add anything in config.plist after adding SSDT — should I?

[mrjayviper]

any ideas on how to generate SSDT for older CPUs (e.g. LGA1366 ones)? Thanks

 

[telepati]

Piker Alpha's ssdtPRGen script will generate a SSDT you can use to achieve the maximum amount of power states for your desktop CPU. Please note that desktop power management is not mandatory.

Requirements:
Working internet connection

How to Generate a SSDT for Power Management

1. Configure system with appropriate SMBIOS for your CPU using Clover Configurator

2. Open Terminal and download Piker Alpha's ssdtPRGen.sh

curl -o ~/ssdtPRGen.sh https://raw.githubusercontent.com/Piker-Alpha/ssdtPRGen.sh/master/ssdtPRGen.sh

3. That will download ssdtPRGen.sh to your user directory. The next step is to change the file mode (+x) with:

chmod +x ~/ssdtPRGen.sh

4. For default SSDT generation, type:

sudo ~/ssdtPRGen.sh

5. Type n, n

6. Open Finder and in menubar choose Go/Go to Folder...

7. Type ~/Library/ssdtPRGen/

8. Mount EFI using EFI Mounter v3

9. Copy SSDT.aml to /Volumes/EFI/EFI/CLOVER/ACPI/patched/

NOTE: The Power Management SSDT should always be SSDT.aml. If you have an SSDT.aml there already, rename it SSDT-1.aml, etc...

10. Reboot


How to Test Power Management

1. Download and compile AppleIntelInfo.kext using XCode. Or download here: View attachment 160106.

2. Drag AppleIntelInfo.kext to desktop

3. Open Terminal

4. Type:

sudo -s

5. Type:

chown -R 0:0 ~/Desktop/AppleIntelInfo.kext

6. Type:

chmod -R 755 ~/Desktop/AppleIntelInfo.kext

7. Type:

kextload ~/Desktop/AppleIntelInfo.kext

8. Type:

cat /tmp/AppleIntelInfo.dat

The amount of power states will then show in the Terminal window.

Hi there wonderful hackintosh/tonymacx86 people!

I am new on this (also my first post here so bear with me please), but I somehow managed to get my hackintosh up and running, except for a couple of things. I also want to point out that (besides the installation process, which I did before the summer) I have read many posts in here, the guides and in the forums, etc..., during this WHOLE week, but I still don't know if I got it right or if i should worry. Except for the issues explained here, the machine runs VERY GOOD. After dreaming with lines of code and burnt processors I thought I'd ask to the proffesionals.

1. Do I need a DSDT.aml file at all? (for the smooth functioning of the machine on the long run)

I extracted mine on DCPIManager (since Maciasl gave me (2) syntax errors and couldn't compile), but don't notice any difference with or without it. The file is on EFI/CLOVER/ACPI/Patched, and I had been able to boot without it. I don't understand this.

2. Do I need any ssdt.aml file at all? (for the smooth functioning of the machine on the long run)

I used ssdPRGen, according to multiple sources here, to generate mine. And then placed it next to the previous DSDT.aml file along with a ssdt-usb.aml file that I found somewhere for my board. The only difference is that without it, the Intel Power gadget shows idle at 4,00GHz and with it it shows idle at 4,20GHz (applies turbo I think). With or without it, the cpu never goes to a lower idle state, e.g. 800KHz.

The Intel power pic attached is with the ssdt in the right folder. Without it looks the same but "stable" at 4,00GHz, perhaps with even more spikes down.

3. When the computer goes to sleep, as soon as the power led goes off, I can hear as if the machine is rebooting (typical noise from checking cd burner, hdds, etc) but as soon as I press space bar, maybe in 1 or 2 seconds, I'm greeted at the desktop, so clearly the system hasn't ACTUALLY rebooted, otherwise I would see BIOS splash screen, Clover, el capitan login...etc. Right? Is this issue fixable?

4. Second monitor flickers every 2-3 minutes for a few seconds, then main screen also flicker in sync with the other, and then the secondary screen goes off for 30 seconds or so, then comes back to "normal". This repeats infinitely. My main screen is connected via DP and second via hdmi-vga adapter. Yes, I know there's no support for vga but I have read somewhere that with an active adapter might work well. Any ideas?

Hopefully the info provided is enough, if not, please let me know and I will add it ASAP.

I am basically curious to know whether the cpu always spinning at max rate is not good? or is it just a matter of fine tuning for oc, etc? I've read different opinions around...

I use the system primarily for personal use and audio software (pro tools, cubase, logic, etc).

Million thanks to the hackintosh community in general, you guys rock big time! (and SORRY for the long post! :/ )

Edit: IOReg file now attached.
