Hi smbios is MacBook Pro 12.1 I tried with what Herve suggested but still the same.

now I have tried MacBook Air 5.2 because my cpu is exactly like it.

Intel(R) Core(TM) i5-3427U CPU @ 1.80GHz

The problem is both cpumanagment kext and x86 platform plugin are running If I disable cpumanagment  kext then frequency is only 1,7 with both minimum frequency also the same but I get turbo frequencies . I also tried with cpufriend and combinations like Jakelo suggested but no joy.

In Mojave with clover and plugin 1 enable works very well.

Here is the EFi Im using

No, as stated before, you need the SMBIOS of an Ivy Bridge model to obtain proper power management on an Ivy Bridge laptop. You may only use the MBP of a more recent model such as Broadwell MBP12,1 at initial installation (not mandatory thanks to -no_compat_check boot arg) and update (mandatory unless you apply tricks to your SMBIOS) for compatibility reasons with Monterey.

 

Given the likely trouble you're likely to experience, I recommend sticking to Big Sur, the last macOS version too fully and natively support HD4000 graphics.
