I notice that it also generates a DSDT.aml, is this of any use? I am currently running DSDT free with UEFI BIOS.

Using your method I got the following output (cpu is 4770k)

Does this seem right?

Before running the kext I got

Another thing is I get 4 versions of SSDT.aml, i.e. SSDT-3.aml, SSDT-2.aml, SSDT-1.aml and SSDT.aml
Which to choose?

What are the correct settings in config.plist?
What do I need to check/uncheck in Clover Configurator

Thanks man, now I know why I must have this for.

Can you tell me what settings you have in config.plist/Clover Configurator ?

The benefits are that the are more states, so if your desktop is idle it will be at 16 (1.6GHz) or when your rendering a video it will be at 37(3.7GHz) if you did not generate an SSDT it would be stuck at one state.
Can this mechanism be used to provide a sort of "software overclock"?
I've got a i5 3570k @ 4.7 ghz, I've never used any SSDT and I still get 4.7, 1.6, 4.4, and others i can't remember off the top of my head. But how is that possible if there was no SSDT listing for 47 (because I've never modified it)?

From RehabMan's guide:

Note: If you have a CPU currently unsupported by the script, you may have to provide the data for it.

For example, i7-4720HQ:
Code:
./ssdtPRGen.sh -p 'i7-4710HQ' -f 2600 -turbo 3600

By providing the name 'i7-4710HQ' (similar enough to i7-4720HQ), and overrides for the non-turbo and turbo frequencies, the script is successful. Eventually, it would not be necessary, provided the script is updated with the new CPUs.
Now getting this:

Code:
Stus-MacBook:ssdtPRGen.sh-master stu$ sh ssdtPRGen.sh -p 'M-5Y10c' -f 800 -turbo 2000
