Hi guys,

 

I did my first setup today.. (actually it took 5 days). New at this osx stuff and don't know anything about coding.

At first i had pre installation boot loop because of wrong (old) bios version, but at some point i figured it out and managed to make the install.. ofc i had wrong wifi card etc. So at some point i got pretty much everything working. camera, hdmi, audio works everywhere as well. Need some time and i will figure out how to dim the backlight :D .

 

So. My cpu is stuck on like 8x what makes like 800mhz, live youtube videos are laggy (imo best option to measure if the setup is working) tried all sorts of stuff, two days.. cant even point out what i did. (and it goes to all the stuff i got working) just saying that at some point i accidentally put my kext files to 10.13 folder instead of Other and had to learn how to use shell to move those files to get the system booted up again. but about that cpu, i really dont know what to, i'll add archive which contains EFI, and hwmonitor picture.

 

long story but i hope you can help me by giving me some suggestions what to try.

You need to generate your CPU-specific power management SSDT using Pike R Alpha's well-known generator script: https://github.com/Piker-Alpha/ssdtPRGen.sh

Then place the generated SSDT in your Clover ACPI/patched folder.

 

In your Clover config file, I recommend you drop:

  • DMAR
  • SSDT table-id CpuPM
  • SSDT table-id Cpu0Ist

Make sure to leave anything else ticked off. Use Clover Configurator app to that effect.

 

With regards to kexts, caching add-on kexts from /L/E (or /S/L/E if they must go there) is far better than injecting them from Clover kexts folder (whether from the relevant 10.xx or Other folder). All details related to permissions repair + cache rebuilding are available in the FAQ section of the forum.

I tried your ssdt, still nothing.

 

I generated new file again and it didn't change a thing. In drop down, i had those three things, maybe misplaced.. i'll try to do figure out the right way..

 

On the other hand. When i wake up my computer from sleep, then i have a processor speed aroud 2-3k for a few seconds. Then i think some wrong item loads and it drops down to 800 and stays there.

 

I'll search faq section in the evening. (Gotta work)

 

Thanks so far

The Clover config you posted in post #1 is incorrect:

If you adjust it as suggested, you should be Ok. You drop ACPI tables, not actual files!

I also noted in your attachment what seemed to be a proper ssdt for power management of a i7-3520M @2.9GHz (LFM @1.2GHz, HFM @2.9GHz, max turbo boost at 3.6GHz), generated under High Sierra 10.13.2. If this is the CPU model fitted to your E6230, no reason why you would not have proper and full CPU power management once you fix your Clover config. Provided you've installed the necessary FakeSMC PlugIns, HWMonitor app should show your CPU SpeedStep info.

disableturboboost is not installed

 

To get the speeds over that 800 i must delete the ssdt file from patched.. i tried other ticks and whatnots. 

 

Now its working 1,2-3.4ghz

Using DMAR, Drop oem, plugin type 1.

 

in this screen shot i have my LE files, maybe some of them are unnecessary or causeing this weird situation

And you said "disableturboboost is not installed" ? Erm... What's that last kext in your screenshot then?

 

As suggested above, do generate your own CPU-specific SSDT through Pike R Alpha's generator script. Though if you say everything is now working, you're all done I guess!
