Quick Guide to Generate a SSDT for CPU Power Management

iMac17,1 with 1 Ghz
hi I am using the same CPU but my frequency staying always between 2.5-4.2 even on idle, I have used the open core boot loader so have you done any power management SSDTs using cpufriendfriend if you can share or even the SSDTs so I can check as what I missing

Good afternoon, thank you all in advance! well I'm having trouble getting my CPU to work! I can't get the states at all. I've already added several ssdt to my CPU, but nothing solves! some help!? i am trying to use the ssdt i5 OC.
best regards
 
Pls beware, this doesn't work anymore, after step 3 it aborts.
 
Easiest way for Ivy is to ignore ssdtPRgen.sh entirely...

Instead:
- delete SSDT.aml if you already created it
- set config.plist/KernelAndKextPatches/KernelXCPM=true
- set config.plist/ACPI/SSDT/Generate/PluginType=true
- make sure you're not dropping OEM CPU SSDTs (eg. DropOem=false, no CPU SSDTs identified in DropTables)

Would this work for Ivy Bridge - EP? I got a Sierra 10.12.6 install on a Sabertooth X79 with Xeon E5 1680 v2.
 
Is there a particular reason why IGPU pstates could be missing however CPU PM works fine? (i7-5775c, iris 6200 pro, clover, WEG, imac 16,2). Everything works but the gpu is stuck @300mhz. Tried all sorts of options, acpi patches, injections methods, igfxrpsc=1 in weg, nothing seems to work..

is this support Coffee lake CPU?
Mine gave unsupported CPU.
