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.
