Hey looking through the code, the standard clock rate is 550MHz correct? Did you get to play to overclock them at all?
Correct. They ran at 79 degrees at (the default) 550MHz but I did not try higher speeds. I do not know if the cooling (which is water based) adjusts itself dynamically in any way for a target temperature or if that's as good as it gets so I cannot surmise how much scope there is for higher speeds with default cooling.
