Is It Possible to Turn Off E-cores (Efficiency Cores) in BIOS on 12th Generation Intel® NUC Models?

Can the E-cores be turned off in BIOS for 12th Generation Intel® NUCs?

Intel does not recommend turning off the E-cores, as this may negatively impact system performance, and at least one E-core will remain enabled (not all of them can be turned off).

To turn off the E-cores, follow these steps:

1. Access the System BIOS.
2. Go to Power, Performance and Cooling menu.
3. Set External Ambient Temperature -Tolerance to User Defined.
4. Click on Performance.
5. Click on Processor.
6. Set all Active Atom Cores to 1.
