Got some info from friedcat today

"The multipliers of our chips are fixed (28x), so you could only change the oscillator frequency to achieve higher internal frequency. The oscillator of choice (12MHz) is fixed so overclocking will involve re-soldering of a new oscillator with higher frequency. Also, the resistor controlling AOZ1021's output voltage needs change.

Best regards,

So I am working up a order for the parts needed to overclock Smiley My Target speed is 400mhz.
It is not a simple crystal, you need a oscillator to do the overclocking.
Still Need to reverse the power section of the asic to determine how to increase the voltage.
I also have a programmable oscillator on its way so I can fine tune the speed of the asic Smiley (up to 800mhz if it can take it but i doubt it :p )
