Thank you RehabMan. I gave up, went back to windows 10, a lot of problems arose. The Hp suddenly started rebooting time after time, it became frustrating. Thanks
 
did i get this correctly?
i have a i7-3770K (not overclocked) on a H77 dell Motherboard.

here is the output but I think i doesnt have as many P-states as others on this thread.

CPU Ratio Info:

------------------------------------

CPU Low Frequency Mode.............: 1600 MHz

CPU Maximum non-Turbo Frequency....: 3500 MHz

CPU Maximum Turbo Frequency........: 3900 MHz

CPU P-States [ (16) 34 35 ]

CPU C6-Cores [ 2 4 6 7 ]

CPU C6-Cores [ 2 3 4 5 6 7 ]

CPU P-States [ (16) 33 34 35 ]

CPU P-States [ (16) 32 33 34 35 ]

bash-3.2#

Any advise? Thanks for the help!
 
Hello everyone!
I was successful installing High sierra on my C621 platform . I met a problem that I can't add unkown processor model of dual lntel xeon Gold 5117 in the User Defined list. Maybe I make mistake with this step.
This code is here.
'Xeon 5117',105,1200,2000,2800,14,28,1,100
 
Just tried to create a SSDT for a i3 3225 on a Dell 7010 with the release version of Mojave (sys def 13,3), after the clock was set and stuck to 800Mhz on the cpu and 350Mhz on the GPU. Simply removing the SSDT gets speedstep working with a reasonable number of speeds and Im ok with that but interested in how the software can get an 800Mhz clock speed out of a chip that supposedly only goes down to 1600Mhz.

Exact same issue. Was working fine on HS. Yet, after updating to Mojave it got 800MHZ and slow performace. Any idea how to resolve this issue?

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

Code: 
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:

Code: 
chmod +x ~/ssdtPRGen.sh

4. For default SSDT generation, type:

Code: 
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:

Code: 
sudo -s

5. Type:

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

6. Type:

Code: 
chmod -R 755 ~/Desktop/AppleIntelInfo.kext

7. Type:

Code: 
kextload ~/Desktop/AppleIntelInfo.kext

8. Type:

Code: 
cat /tmp/AppleIntelInfo.dat

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