Excellent! Your work is fantastic! How long can the chip last running like this? I wonder if you tried cooling it? Is this using a custom crystal? How many props were destroyed in testing the outer limits? Great work guys!!! Hope you have some links posted to find all this at the Parallax Forums (pm me). I cannot access this youtube site again as I will be traveling in China where youtube is blocked.
Well as you can see from the Video I have successfully clocked it over 140MHz but you have to crank the core voltage up above 3v3 which is way above spec. There are some new boards coming out soon from another developer that has better power and ground planes which makes the Prop much more stable at higher speeds.
Check us out on the Parallax forum, Coley and Baggers :D
@PropGFX I believe that at 140MHZ, you can achieve 1 clock cycle for one instruction which speeds the Propeller up by a factor of 4x, am I right? I just received a Chameleon AVR, which has a Prop chip on there, so I'm not completely familiar with the system yet :). Just a question, is all.. haha!

Or.. maybe just speed up the video so it will look like a "overclock"

Yeah, that's possible I suppose, check out the rest of our work though ;)
Propeller is stable at 120MHz that 50% above spec, that's 30 MIPS x 8 Cores not bad for an $8 MCU

Ok, I believe you :)
I just bought a propeller few days ago and it's nice to know that it can even be overclocked.
Keep up the good work ;)

The world isn't ready for such power! ;-)
