Yes, "K10" and "family 10h" are synonyms. But anyway, the family 10h sensors are known to be unreliable so they will never be supported. I'll update sensors-detect in a minute so that it stops giving false hopes to users. > The sensors(1) app appears to pick up temperature readings from my > system, but I'm not able to figure out the mapping of the values I'm > getting (sample below): > > $ sensors > it8718-isa-0228 > Adapter: ISA adapter > in0: +1.04 V (min = +0.00 V, max = +4.08 V) > in1: +1.95 V (min = +0.00 V, max = +4.08 V) > in2: +3.30 V (min = +0.00 V, max = +4.08 V) > in3: +2.96 V (min = +0.00 V, max = +4.08 V) > in4: +3.06 V (min = +0.00 V, max = +4.08 V) > in5: +4.08 V (min = +0.00 V, max = +4.08 V) ALARM > in6: +4.08 V (min = +0.00 V, max = +4.08 V) ALARM > in7: +2.03 V (min = +0.00 V, max = +4.08 V) > Vbat: +3.30 V > fan1: 2537 RPM (min = 10 RPM) > fan2: 0 RPM (min = 0 RPM) > fan3: 0 RPM (min = 0 RPM) > fan4: 0 RPM (min = 0 RPM) > temp1: +44.0°C (low = +127.0°C, high = +127.0°C) sensor = thermistor > temp2: +37.0°C (low = +127.0°C, high = +60.0°C) sensor = thermal diode > temp3: +46.0°C (low = +127.0°C, high = +127.0°C) sensor = thermistor > cpu0_vid: +1.550 V You should be able to figure out fan mappings by comparing with what the BIOS says. For temperatures, temp2 would be the CPU temperature, while temp1 and temp3 would be mainboard temperatures. Again, comparing with what the BIOS says should help. The fact that the CPU temperature is lower than the system temperature is somewhat suspicious, although not impossible. For voltages it's a little more difficult. Checking what the BIOS reports would definitely help. For reference, the recommended wiring for the IT8718F is: in0 -> Vcore1 in1 -> Vcore2 in2 -> +3.3V in3 -> +5V (scaling factor 1.68) in4 -> +12V (scaling factor 4) in5 -> -12V in6 -> -5V in7 -> +5V Stand-By (scaling factor 1.68) But in practice most boards no longer monitor negative voltage lines any longer, and as a matter of fact your board doesn't. So you can start with: ignore in5 ignore in6 And CPUs tend to have a single Vcore these days so in1 is more likely Vdimm. So a first approximation would be: label in0 "Vcore" label in1 "Vdimm" label in2 "+3.3V" label in3 "+5V" label in4 "+12V" compute in3 @ * 1.68, @ / 1.68 compute in4 @ * 4, @ / 4 Not sure about 5VSB. If you come up with a good complete configuration, please post it so that we can add it to the wiki. > Can you help me understand whether I need to wait for a K10 driver, can > use the subject patch, or need nothing?

Don't wait for a patch or new driver, there won't be any. Best thing you can do is tweak your IT8718F configuration to match your mainboard. -- Jean Delvare http://khali.linux-fr.org/wishlist.html _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
