Yesterday I turned one of the boards back to 1.2GHz (3pm), and it died during the night (2am). The 920MHz is still working. The room temperature didn't go over 26C (the thermometer is by the boards).
Status update:
One of the boards failed at 920MHz @ 60% temperature levels. I blamed the power supply and switched to make sure the *other* board would fail as well at 920MHz, which it did. So I retired that power supply and am using a third one, all cheap (all I have here).
I know others have said this, but since you seem to not yet be convinced: the frequency is a red herring. If your PSU can't really keep up with the Panda, all bets are off. We early on in the LAVA lab figured out they only ran reliably on those massive (IIRC, 4A) bricks that Digikey sells.
