A modding question

Thu Dec 13, 2018 5:12 pm

Hi all,

I wonder if anybody tried changing the main CPU crystal , from 19.2MHz to something else, but still close to it.
For example 18.432 or 22.5792 MHz.
What would happen, besides under/over clocking the CPU this brute force way?

I've decided to give it a try, it boots with 18.432MHz, I've still got hdmi and usb.

Out of curiosity, which SMD component is the crystal oscillator on a Pi?
None of the things I saw looked anything like what I'm used to seeing.

It is squared, one is marked 19.2, the other one 25.
