@RhabMan Thanks for your tutorial. I have a two LGA 3647 CPU platform and I could not genrate SSDT for it. So these two CPU could not have CPU turbo.
Could you please make tutorial for these CPU which SSDTpregen recognize them as unkown tpye?
Machine model is DEll 7920. Sorry for my poor English

config.plist/ACPI/SSDT/Generate/PluginType (true/false): Determines whether the "plugin-type" property is injected or not.
config.plist/ACPI/SSDT/PluginType (integer): Determines the value for "plugin-type" property when it is injected. The only valid value is 0 or 1. And the only setting that makes sense is 1, as there is no point in injecting "plugin-type"=0 (might as well not inject it).

I changed the recommended settings with clover.
But the max clock is still 4,3GHz even if just one core is under load. Temperatures are around 50° C, power consumption around 30W. Under windows it run with 4,7GHz with the same test.

Im facing different temps (windows 78º/ mac 88º) with my hack overclocked.
Is this related to power management?
thanks in advance

I have the same/similar issue(s) with sleep/restart/shutdown (and strangely even closing SysPrefs->Startup Disk after changing the startup disk) on my CoffeeLake NUC8.

Earlier this year, I'd generated a ssdt.aml for my i7-3770k, following the guide, for High Sierra and power management worked.
CPU @ 1.6 at idle and stepped up to 4.6 at load.

I upgraded to Mojave earlier this week and copied the existing ssdt.aml file to the /clover/acpi/patched folder.
My CPU is @ 3.5 all the time. I generated a new ssdt.aml in Mojave, CPU still at constant 3.5.

Is there something I need to tweak in config.plist or additional files I need to copy to \clover or \EFI?

Any help appreciated.

Maybe something you intalled is causing CPU usage when you don't expect it?
Did you check that?

I just checked the activity monitor and my CPU is 97%+ idle. I'd encountered the same x35 situation prior to using ssdtPRGen to generate the ssdt.aml file in 10.13.

Is there something other options on my config.plist that I should enable/disable, in addition to the custom ssdt, to get my CPU power mgmt back to "normal"?

Thanks!

No "Problem Reporting" files attached.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.

Use the gen_debug.sh tool mentioned in the FAQ, that way it is less likely you'll omit something.
