看库函数中system_init函数中有这样一段代码
#if defined(STM32F427_437xx) || defined(STM32F429_439xx) || defined(STM32F446xx) 
    /* Enable the Over-drive to extend the clock frequency to 180 Mhz */
    PWR->CR |= PWR_CR_ODEN;
    while((PWR->CSR & PWR_CSR_ODRDY) == 0)
    {
    }
    PWR->CR |= PWR_CR_ODSWEN;
    while((PWR->CSR & PWR_CSR_ODSWRDY) == 0)
    {
    }      
    /* Configure Flash prefetch, Instruction cache, Data cache and wait state */
    FLASH->ACR = FLASH_ACR_PRFTEN | FLASH_ACR_ICEN |FLASH_ACR_DCEN |FLASH_ACR_LATENCY_5WS;
#endif /* STM32F427_437x || STM32F429_439xx || STM32F446xx */

所以F427可以配置成180Mhz吗？F407只有168Mhz吧？
如果我依然把F427配置成168Mhz，上面一段代码会不会对我的配置产生影响？
