Clock configuration for timers

After doing some primary embedded projects (LED, user button etc) on my MCU (Nucleo-64 STM32 F411RE) I'm now dealing with timers. Here's my clock configurations

1- Does anything look wrong?
2- While my clock rate is 100 MHZ (as written on my board pack), should I change that 84 (in the HCLK (MHz) field) to 100 in the configuration?

You don't have to change that, but you can if you are in need for more cycles or special frequencies.

@mƎALLEm I never figured out why the initial clock settings are as they are, also for other series.

Hello,

All seem ok as soon as there was no Error/warning indicated by CubeMX
