STM32F3-Discovery HSI clock source

My stm32F3-discovery does not have an external crystal(HSE) fitted to it.

I set up a new project with CUBE and according to CUBE clock configuration figure, the MAX clock speed I can achieve with HSI(8Mhz), is PLL(64Mhz).

Is this correct, because I seem to remember a post I read and cannot find anymore, that even when using HSI(8Mhz) the F3 can be configured for 72Mhz??

Can someone clear this up please. An example as to how to setup the F3 would be fantastic.
