Hi, I have lm_sensors 3.0.2 on a supermicro X7DWA-N with kernel 2.6.25.15, I am trying to work out how the lm_sensors voltage readings map to the sensors shown in the bios and described in the motherboard manual, the manual states: Onboard Voltage Monitors for the CPU Cores, Chipset Voltage, Memory Voltage, +1.8V, +3.3V, +5V, +12V, -12V, +3.3V Standby, +5V Standby and Vbat sensors output: VCoreA: +1.20 V (min = +0.92 V, max = +1.49 V) = CPU Cores VCoreB: +1.20 V (min = +0.92 V, max = +1.49 V) = CPU Cores Vtt: +1.08 V (min = +0.99 V, max = +1.33 V) = ? in3: +0.51 V (min = +0.38 V, max = +0.69 V) = ? in4: +1.46 V (min = +1.34 V, max = +1.65 V) = ? +3.3V: +3.28 V (min = +2.96 V, max = +3.63 V) +3.3V? +12V: +11.81 V (min = +10.75 V, max = +13.25 V) +12 +5V: +5.02 V (min = +4.64 V, max = +5.65 V) +5 5VSB: +5.05 V (min = +4.64 V, max = +5.65 V) +5V Standby VBAT: +3.18 V (min = +2.99 V, max = +3.66 V) Vbat Can anybody explain the differences?
