CPU remains in Idle mode

What is idle mode? When you resume from Windows Sleep mode, is your CPU stuck at 1400 MHz? Have you gone to the ASRock website and downloaded and installed the latest bios for your motherboard? A problem like this might have been fixed in the latest bios.

If you want to save power, make sure you have enabled the C States in the bios. A CPU core in the low power C7 state is sitting at 0 volts and 0 MHz. This happens automatically when the C states are enabled. Any other power saving trick cannot compete with 0 volts and 0 MHz.

Your CPU is not overclocked. 3.6 GHz is the default speed. When 1 core is active, Intel Turbo Boost will boost that up to 4.3 GHz. When 2, 3 or 4 cores are active; the CPU should boost up to 4200 MHz and when 5 or 6 cores are active; a Core i5-8600K will boost up to 4100 MHz. If you are running your 8600K at 4 GHz, you are running it at less than its default speed. This is called under clocking and should be avoided. Go into the bios and set your turbo ratio limits appropriately or set your turbo ratios to AUTO.
Go into the Windows Power Options and make sure you are using the Windows High Performance power profile with the Minimum processor state set to 100%. Also make sure that SpeedStep is enabled in the bios. On some motherboards, disabling SpeedStep will cause issues like you are having with the CPU getting stuck at a fixed frequency.
