How would I go about figuring out the scaling > factor? I can't find it in the datasheet but I'm almost certain the chip uses 6.8 kOhm and 10 kOhm resistors internally to scale the voltage down to the measurable range. This leads to: compure in3 @ * (1 + 6.8 / 10), @ / (1 + 6.8 / 10) This should give you a valid +5V reading. It is odd that the BIOS won't show it. > in6 at 1.12V and in7 at 4.08 are both outside that range. in7 is saturated, definitely not used. If in6 could be used, for example for -12V, but we can't label it. If it stays stable, you can leave it visible. > > in8 is normally Vbat on the IT8716F, it shouldn't need scaling.

Plus many recent boards backup the battery with 3VSB while the system is powered, to extend the battery life, so values above 3.0 V aren't unusual. > > > (...) > > > # Min and max for Athlon II X2 245e > > > set in0_min 0.875 > > > set in0_max 1.4 > > > > Did you check if the BIOS had set proper limits on its own? > > No. Would that be the limits given before I did "sensors -s"? Yes, after a cold boot. -- Jean Delvare _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
