Hi,
This may become a general problem: we might get it up to 1.7GHz peak clock rate by fixing the freeze issue, but thermal throttling might reduce the average clock rate to let's say 1.2GHz. Then it is the same as running them permanently at 1.2GHz.
Maybe, is this the reason why TI dropped the 1.7GHz specification because nobody can use it 100% of the time without overheating the chip even with active cooling?
Linux-Swat is running his devboards (with a better passive cooling than the original) at 1,7GHz without overheating.
So the "freeze-barrier" is somewhere between 1.0 and 1.1 GHz.
For the CPU only and NEON, yes. Don't forget that using the 3D GPU will need more power, so it might freeze with 1GHz already as well.
