[Guide] - SSDT with Pike's PM Script and use with CPUFriend

[platinumsteel]

Yes when i do i get the error i sent u previously..About Unknown CPU

not sure if you had replaced the DATA folder with the one I uploaded

Hi,

I9-9900k,95,800,3600,5000,8,16 have been added to Coffee Lake.cfg and User Defined.cfg.

Open a terminal

./ssdtPRGen.sh -p 'i9-9900k' -f3600 -turbo5000

Press enter

It stops in this state. It is not possible to proceed.

Is something missing?

[ref]yumo[/ref], u need use it only if ur processor don't down in iddle to 800mhz(minimal frequencies, need check specs)

Thanks for your time. I know you're busy.

The processor goes down to 800 mhz.

So not seem necessary to me.

Are there any issues with running ssdtPRGen.sh in the latest released version of Mojave 10.14.4? I keep getting unknown processor and the processor is in Coffee Lake.cfg and I have followed the steps. I was successful running this on another laptop that is Kaby Lake but that version of MacOS is 10.14.2 this is why I am asking if anyone has tried running ssdtPRGen.sh in 10.14.4 without any issues?

My mobile processor is i7-8750H and won't go less than 1000Mhz x13 CPU Package Multiplier so I need to run it, I want it down to x10 800mhz minimum. My friend ran this for me on my laptop a month ago since I was new to this procedure and I was on MacOS version 10.14.3 no problems running ssdtPRGen on that version and it brought it down to x10 800mhz. I am trying this procedure myself now but I am on MacOS 10.14.4 and I keep getting this unknown processor.

The ACPI folder is created after running ssdtPRGen.sh inside the ssdtPRGen.

Also hello to MaLd0n .

[osxfr33k]

Some of us might prefer to use injector kext instead of SSDT. This is how its done.

Creating injector kext with CPUFriend script

1. Type

./ResourceConverter.sh --kext

2. Drag ssdt.aml from ~/Library/ssdtPRgen folder to terminal and Press Enter

3. Your CPUFriendDataProvider.kext will be generated and can be found at ~/Desktop/CPUFriend-master/ResourceConverter folder

4. Place both CPUFriendDataProvider.kext and CPUFriend.kext in clover/kext/others

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Unknown CPU

What if I have a CPU that is unknown and not in the .cfg list? Can I still generate ssdt using Pike's script?

Yes. And this is what we have to do.

1. Determine CPU details by going through https://ark.intel.com and fill in the details for an i5-8600 as an example.

 

Code Name: Coffee Lake
Processor Number: i5-8600
Max TDP: 65
Low Frequency Mode: 3100
Clock Speed: 800
Max Turbo Frequency: 4300
No. of Cores: 6
No. of Threads: 6

 

The format to be input in Coffee Lake. cfg and User Defined.cfg will look like this

 

i5-8600,65,800,3100,4300,6,6

 

If I go with this step do I still need step B and Step C or just Step A followed by the procedure I quoted? Reason I ask is because if I skip part B and C and compare the injector data, some cf-frequency-data is lacking in the injector but also duplicated to.

[onemanosx]

If I go with this step do I still need step B and Step C

No. Proceed with kext creation after creating ssdt.aml

[osxfr33k]

No. Proceed with kext creation after creating ssdt.aml

 

Thanks for clearing that up. I also posted about unknown processor and have been trying everything I know I can do and ssdtPRGen keeps telling me unknown processor even though I have followed all the steps. My friend has the Walmart brand OverPowered 15 inch with i5-8500H and MacOS 10.14.4 and is able to run ssdtPRGen no problems. I have the 17 inch i7-8750H and now on MacOS 10.14.4.

Any ideas or work arounds?

[ref]osxfr33k[/ref], just ignore the warning. SSDT should still work good.

It never creates the ssdt.dsl or ssdt.aml. It does create the ACPI folder, look at my post above after running ssdtPRGen it aborts.

[onemanosx]

[ref]osxfr33k[/ref], you must have missed a step.

Instead, you can just use clover's plugin-type. It works as good.

I still use plugin type and cpufriend because with cpufriend I get down to 1000mghz at x10 without cpufriend I have 1300mhz at x13. Originally my friend created the ssdt.aml with ssdtPRGen, so I do have a working cpufriend and CPUFriendDataProvider, I just wanted to get the ssdt.aml again and it got deleted. I don't understand why it just stopped working after installing 10.14.4 or something else went wrong trying to figure out exactly what.

Sorry I did not put my other PC in signature, its an OverPowered Laptop OP-LP3, a Walmart brand has an i7-8750H processor that is the one I am trying to get a ssdt.aml with.

[erroruser]

[ref]osxfr33k[/ref], did you add the information for the cpu in the data files if its not listed in them

Yep followed the guide perfectly. Maybe for some reason which I cannot explain it’s not reading the Coffee Lake.cfg. I know it’s reading the User Defined.cfg because if I leave a couple spaces or something the CFG file should not contain it complains in the output showing such lines in cfg needs attending to. This happens when you don’t edit them in terminal with like nano or equivalent editor that will not change the format of the cfg. If I remove the Coffee Lake.cfg it doesn’t complain is why I suspect that for some reason ssdtPRGen is not reading the Coffee Lake.cfg file but it is reading the User Defined.cfg.

I have never been so baffled by something like this.

[erroruser]

in the data folder that is in your ⁨Users⁩ ▸ yourname ▸ ⁨LibraryssdtPRGen⁩ data folder in the user defined doc did you add as so

#

i7-8750H,35,600,2200,4100,6,12

)

as i added an give it a try

Yes added that exactly as you have and exactly as instructions say.

[erroruser]

try with the one i sent see if that helps

[osxfr33k]

Wow thanks so much it worked!! NOw I Have to figure out why mine does not work I attached mine can you see what is wrong?

[erroruser]

looks like you added in wrong

[osxfr33k]

looks like you added in wrong

 

I attached the wrong file I was testing my friends CPU check the new file I attached and let me know if you see anything wrong with it.

[erroruser]

there is no file

[osxfr33k]

there is no file

 

Sorry here it is this one does not work maybe you can explain I cannot see anything wrong with it.
