STM32 Tick Clock source problem

#if!defined (Hse_value)
#define Hse_value ((uint32_t) 24000000U)/*!< VALUE of the External oscillator in Hz */
#endif/* Hse_value */

The size of the Hse_value value determines the period in which the clock ticks. The setting of this value does not affect the clock cycle of the main frequency and the changes of the associated timer.
