[Guide] Generate SSDT For Coffee Lake CPU

Status
Not open for further replies.
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.
 
Debug zipfile attached.

Thanks.

No need for ssdt.aml in ACPI/patched; remove.

DropTables setttings are wrong.
Remove CpuPm entry in config.plist/ACPI/DropTables.
Remove Cpu0Ist entry in config.plist/ACPI/DropTables.

And why are you posting to a thread for "Coffee Lake"? The hardware represented in this ioreg appears to be Ivy Bridge.

To enable XCPM on Ivy Bridge, set config.plist/KernelAndKextPatches/KernelXCPM=true.
 
Hello @RehabMan, thanks for your contributions here! I am having trouble getting C states / turbo boost to work with the i9 9900k in Mojave. I have tried PluginType=True and KernelXCPM with no luck. According to HWMonitor the cpu never reaches above base clock setting in BIOS. I am not showing CPU0 at all in ioreg either.

I am on 10.14.1 w/ iMac18,3
