Hello   Neither of those options will affect the CPU frequency or power states.   This is a power and cooling option. Nominal will set fans to run at normal speeds. Level 1 will decrease fan speeds.   This enables or disables the newer communication method of the CPU. This should only be disabled if the operating system does not support it. The CPU will operate more efficiently with this enabled. It may affect performance but not in raw MHz or turbo states. Thanks
