(And where does that formula originally come from? Is it simply an empirical formula someone came up with?) I have an A7V333 motherboard which also contains a ASB100 sensor chip. I found out that the data in register 0x17 corresponds exactly to the temperature reported in the BIOS. Register 0x17 is in a range undocumented by the w83781d and lm78 datasheets. The 'regular' temperature register usually reports a higher temperature, but strangely enough is seems to respond slower to changes in CPU load than the register 0x17 temperature.
