I wouldn't trust any display of frequencies in macOS system information. I guess it just displays the name of the processor and its standard frequency of 3,5 GHz, whereas the boost/turbo frequency is never displayed. Try to run GeekBench once with overclocking, and then without to determine the effect of your overclocking in macOS.

Thank you very much for answering. A few moments ago, I fixed it. The cause of the problem was due to a kext (NullCPUPowerManagement.kext) that I forgot was installed. I removed it, and the overclock works. Then I tried with a custom SSDT frequency, but I got better results in GeekBench removing the SSDT and activating the plugin-type=1 in Clover and adding the SSDT-XCPM.aml, along with CPUFriend.kext and CPUFriendDataProvider.kext (calibrated for iMac 14.2). To run the sleep completely, I used the SMBIOS of iMac 14.2.
Thank you very much for having answered. Thank you very much! And have a good day.
