Configuration differences STM32F401 to STM32F4?

I just try to get an STM32F401 running, but it somehow does not seem to work with the standard STM32F4 system-startup files (e. g. from STM32F4 discovery).

Is there some comparison PDF about necessary changes when going from e.g. STM32F405 to STM32F401? (especially concerning software modifications - I assume mainly concerning the RCC registers)?

Or anyone has any hints? Or should it run without changes?

PS: I just downloaded the STM32F401 Discovery software firmware pack. From the folder organisation, this seems to be more or less a copy of the STM32F4 Discovery stuff. It would be really very helpful to get some information, in which files there might be some possible differences.
