Event Viewer message "The speed of processor 0 in group 0 is being limited by system firmware". The OS (e.g. Windows 8.1), doesn't take into account power saving features (SpeedStep) of mobile CPUs (e.g. i7-4600U). The SpeedStep feature of mobile processor decrease CPU speed when possible (for example during loading OS files from disk during the boot) and it caused the OS to think that CPU's speed is limited.
This feature doesn't affect overall system performance, it always switches to maximal speed when CPU is fully loaded.
This event viewer message is a false flag!
