I am using STM32F410RB 64 pin MCU. According to datasheet, its max clock is 100MHz. I am using cubeIDE for clock setting and programming. The problem i am face is that my MCU is only operating for 60MHz max. any frequency setting above 60MHz is not  working. I have verified my clocking setting parameters, it doesn't have any error. kindly let me know what possibly is creating this issue. i am attaching my clock setting screen shoot.

Thanks a lot. My bad, My PCB connection was wrong. V_Cap1 was connected at pin 31 instead of pin 30. Its working perfect now. :D
