Is there any way to further diagnostic the reason for the displayed limit?
If my system is idle, the limit is 4850MHz. Running CB20 multicore bench or cpu-z multicore stress lowers the limit to 4650MHz?
See attached screenshot for details. What's the limit?
The CPU periodically checks several working parameters and their respective limits like PPT, TDC, Temperature, High-temperature Fmax, PROCHOT, VID, etc. and based on this outcome enforces the current frequency limit.
