Can F469NI run at 180mhz

I was hoping the F469NI would be running at 180mhz, but it's running at 168mhz. Is it possible to configure for 180mhz?

Question relating to:

The STM32F469 Discovery kit (32F469IDISCOVERY) allows users to easily develop applications with the STM32F469 high-performance MCUs with ARM®Cortex®-M4 core and Chrom-ART Accelerator™.

Yes. However due to the clock circuit inside of the 429 it can not support USB at 180MHz. If you download the STM Cube Mx application software from st.com you can tweak the clock speed as desired and take the code it generates and merge it with mbed.
