SystemClock_Config issue on STM32f769NI only for 200mhz sysclk and higher

Hi All,
Due to CPU package change, I tried to change the CPU from Keil project configuration. But the new project does not work. So when I check the problem part, it is SystemClock_Config() where I am configuring the sysclk. I want to achieve 200mhz system clock.
To be more clear, it is a STM32f769NI based project which is not working while stm32f769BI based project is working without any issue. I have not changed anything but only the CPU. I have verified with two of my new hardware's. Unfortunately I do not have any evaluation board to verify this.

To make it simpler, I copied RTX blink example program with 25MHZ clock. Since my hardware is 8mhz, I just reconfigured those clock portion such as OS_CLOCK = 200mhz, Xtal = 8mhz, HSE_VALUE = 8mhz.

When I tried to configure the CCR to achieve HCLK = 200MHZ, It always goes to Hardfault_handler or Can not stop debugger state whether the clock source is HSI or HSE.
Using MCO2 on PC9 pin, I am able to see the PLLCLK is generating 200MHZ when it does not completely dead. with the AHB prescaller is set to 1, HCLK is supposed to be same as PLLCLK.

I compared the working board CPU RCC registers and not working board CPU RCC registers. It is more or less same(Same in the necessary section).

Just to try, I reduced the clock to 150MHZ by changing the PLLM and PLLN, I am able to see the LED blinking. And I am able to see the LED blinking when I comment out the OS functions or use MicroLIB with RTX with 200mhz sysclk.

When I tried to trace the hardfault source, it is showing different unknown address different time.

Can anyone help me understand the problem?
