Your screenshot shows that SpeedStep is disabled. Check that box and check the Set Multiplier option. That should help.
Better yet, go into the TPL window and enable Speed Shift. This is the preferred method to control CPU speed on a modern Intel CPU. When Speed Shift is enabled, you will see SST in green on the main ThrottleStop screen. Now you can check the Speed Shift - EPP box and set EPP to 0 for maximum performance or set it to 80 for something similar to the Balanced power profile.
If you are going to use Speed Shift, you do not need to check SpeedStep or Set Multiplier. Choose one CPU control method or the other. No need to choose both.
