lm_sensors: 2.9.1 I have a Gigabyte GA-K8N Ultra-9 motherboard (http://www.giga-byte.com/MotherBoard/Products/Products_GA-K8N% 20Ultra-9.htm) The documentation states it uses a IT8712F chip and sensors-detect selected it8712-isa as it should. Temperature readings are sane, fan readings are sane too once the divisor has been bumped a little, but voltage readings are complete junk. Note the BIOS and Giga-byte Easytune tool only check VCoreA, +3,3V, +5V, +12V and CPUVid, so lots of sensors may not be connected to anything on this board The readings with the default config are : [root@rousalka nim]# dmesg | grep powernow powernow-k8: Found 1 AMD Athlon 64 / Opteron processors (version 1.50.4) powernow-k8: 0 : fid 0xe (2200 MHz), vid 0x6 (1400 mV) powernow-k8: 1 : fid 0x2 (1000 MHz), vid 0x12 (1100 mV) [root@rousalka nim]# cpufreq-selector -f 1000000 [root@rousalka nim]# sensors it8712-isa-0290 Adapter: ISA adapter VCore 1: +1.09 V (min = +1.42 V, max = +1.57 V) ALARM VCore 2: +2.56 V (min = +2.40 V, max = +2.61 V) +3.3V: +6.56 V (min = +3.14 V, max = +3.46 V) ALARM +5V: +5.35 V (min = +4.76 V, max = +5.24 V) ALARM +12V: +11.84 V (min = +11.39 V, max = +12.61 V) -12V: -11.77 V (min = -12.63 V, max = -11.41 V) ALARM -5V: -2.83 V (min = -5.26 V, max = -4.77 V) ALARM Stdby: +3.41 V (min = +4.76 V, max = +5.24 V) ALARM VBat: +2.94 V CPU Fan: 1102 RPM (min = 998 RPM, div = 8) Top Fan: 922 RPM (min = 700 RPM, div = 8) Back Fan: 922 RPM (min = 700 RPM, div = 8) M/B Temp: +25

This is a user-space configuration issue, not a kernel bug. Ask your motherboard manufacturer for technical data on how the hardware monitoring inputs of the IT8712F are wired.
