Occasionally, an application may require that you disable Efficiency cores that are part of your Intel CPU.
This is a rare need, but, if you are instructed to do so by a software manufacturer, you may disable E-Cores in your Rok Box's BIOS/UEFI Configuration.
To do so:
Boot the system and press DEL repeatedly as it boots.
The BIOS will load.
Once there, navigate to the Tweaker menu:
In that menu, set Hyper-threading technology to Disabled.
Then scroll down until you see CPU cores enabling mode.
Set this mode to Selectable Mode.
Under Active P-Core/E-Core, set the E-cores to disabled.
Then navigate to the Save & Exit tab and select Exit saving changes.
The PC will reboot and load Windows.
