Setting HSI48 as STM32F072 sysclk

I am trying to set HSI48 as my sysclock on STM32F0 Discovery, but by doing this I somehow ended up with an unexpected interrupt and stuck in an infinite loop.

I am using True Studio by the way. Not using CubeMX or peripheral lib, just old fashioned reg manipulating.

Anyone had any luck at this? Or are we stuck with HSI 8MHz x 8 PLL to get 48MHz CPU clock?
