First, please subscribe me to this list, faq 6.4 says there's no automatic subscription. My email address is <roverr at dogpound-is-a-geek.org> Second I'm trying to get lm-sensors 2.70 on debian to work with my asus a7v8x-x motherboard. I have an initial cut at sensors.conf, it might help others and possibly someone will have ideas for improvement. My it87 section of sensors.conf, alarms modified for my particulars, as usual your mileage may vary. ....... chip "it87-*" "it8705-*" "it8712-*" # The values below have been tested on Asus CUSI, CUM motherboards. # Voltage monitors as advised in the It8705 data sheet label in0 "VCore 1" label in1 "VCore 2" label in2 "+3.3V" label in3 "+5V" label in4 "+12V" label in5 "-12V" label in6 "-5V" label in7 "Stdby" label in8 "VBat" set in0_min 1.5 * 0.95 set in0_max 1.5 * 1.17 <=== my Tbred runs at 1.65v but the voltage resolution seems inadequate, increase upper alarm set in1_min 2.4 set in1_max 2.6 set in2_min 3.3 * 0.95 set in2_max 3.3 * 1.05 set in3_min 5.0 * 0.95 set in3_max 5.0 * 1.05 set in4_min 12 * 0.95 set in4_max 12 * 1.05 set in5_max -12 * 0.95 set in5_min -12 * 1.05 set in6_max -5 * 0.95 set in6_min -5 * 1.05 set in7_min 5 * 0.95 set in7_max 5 * 1.05 #the chip does not support in8 min/max # vid is not monitored by IT8705F # and is not supported by driver at this time ignore vid ignore in1 <==== ignore vcore2 ignore in5 <==== ignore -12v ignore in6 <==== ignore -5v # If 3.3V reads 2X too high (Soyo Dragon, for example), # comment out following line. # compute in2 2*@ , @/2 <===== comment this out # compute in3 ((6.8/10)+1)*@ , @/((6.8/10)+1) compute in4 ((30/10) +1)*@ , @/((30/10) +1) # For this family of chips the negative voltage equation is different from # the lm78. The chip uses two external resistor for scaling but one is # tied to a positive reference voltage. See ITE8705/12 datasheet (SIS950 # data sheet is wrong) # Vs = (1 + Rin/Rf) * Vin - (Rin/Rf) * Vref. # Vref = 4.096 volts, Vin is voltage measured, Vs is actual voltage. # The next two are negative voltages (-12 and -5). # The following formulas must be used. Unfortunately the datasheet # does not give recommendations for Rin, Rf, but we can back into # them based on a nominal +2V input to the chip, together with a 4.096V Vref. # Formula: # actual V = (Vmeasured * (1 + Rin/Rf)) - (Vref * (Rin/Rf)) # For -12V input use Rin/Rf = 6.68 # For -5V input use Rin/Rf = 3.33 # Then you can convert the forumula to a standard form like: compute in5 (7.67 * @) - 27.36 , (@ + 27.36) / 7.67 compute in6 (4.33 * @) - 13.64 , (@ + 13.64) / 4.33 # # this much simpler version is reported to work for a # Eltite Group K7S5A board # # compute in5 -(36/10)*@, -@/(36/10) # compute in6 -(56/10)*@, -@/(56/10) # compute in7 ((6.8/10)+1)*@ , @/((6.8/10)+1) # Temperature # # Important - if your temperature readings are completely whacky # you probably need to change the sensor type.
