The thermometer he used likely showed a much lower temperature than what was actually on the die. 5-10 C more are not unlikely. It's hard to measure chip temperatures accurately without an on die thermal diode or special kit. So I would expect that when an external normal thermometer showed 50C it was already operating out of spec. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
