Max prop overclocking speed

I was just wondering how fast the propeller's max·operating speed is? I am not talking about theoretical limits, i mean actual tested speeds. Come on guys, this is your big chance for bragging rights. I know some people have pushed it over 110 MHZ, but I'm thinking someone else has done even better.

    There's detailed information on this in the Propeller datasheet showing maximum system clock speed vs. ambient temperature and supply voltage. The data points on the graphs are tested.

    It hasn't been fully characterised at those speeds, though.

    I think the fastest so far is 141.875776 MHz by me [noparse]:)[/noparse]

    See this thread http://forums.parallax.com/showthread.php?p=817374
    and a YouTube vid www.youtube.com/watch?v=wbcqR8L3dMo

    A lot depends on the Propeller itself, not all Propellers can do this speed and I only tried with DIP40.

    Regards,

    Coley

    PS It was by no means a scientific test it was done purely for a bit of fun....

    All right, Coley here has 141 MHZ. He is the winner so far.
