STM32F303K8 Nucleo only runs at 8 MHz

Hey all,

I'm using the standard peripheral library 1.2.3 for the F3 series on a Win7 machine running the Keil IDE. 

So while loading the template project, I find that the Sys-clock is only at 8 MHz.

Using the Clock Configuration tool in CubeMX shows me that I can increase the PLLMul to 16 in order to get a 64 MHz clock.

But since this nucleo is advertised as having a 72 MHz part on it, there must be a way to get it to 72 MHz using only HSI + PLL, right? There is no option on the Nucleo 32 board for adding an HSE XTAL.

I'm used to the F4, which has a more flexible clock tree, but here I find there is less opportunity for clock multiplication.

Am I stuck at 64 Mhz? Or is there another way?
