2. This is my (JohnMcPherson's) /etc/sensors.conf file for the
3. LMSensors program for my Gigabyte GA-7VTX motherboard.

set in0_min 1.7 * 0.95 # I think my athlon has a core of 1.7 volts... set in0_max 1.7 * 1.05 # ditto...

1. I'm not sure what vcore2 is actually measuring, but the bios consistently

2. reports around 1.2 or so...

   set in1_min 1.2 * .95 set in1_max 1.2 * 1.05 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

3. in7 == Stdby, seems to be 3 volts, rather than the default 5 in the orig cfg

   set in7_min 3 * 0.95 set in7_max 3 * 1.05

   1. the chip does not support in8 min/max

   ignore vid

4. If 3.3V reads 2X too high (Soyo Dragon, for example),
5. comment out following line.
6. compute in2 2*@ , @/2 # commented out for GA-7VTX

compute in3 ((6.8/10)+1)*@ , @/((6.8/10)+1) compute in4 ((30/10) +1)*@ , @/((30/10) +1)

1. Temperature

2. I needed "temp_type=0x38" as an option to the module at modprobe time

   label temp1 "Temp1/MB" set temp1_over 40 set temp1_hyst 20 label temp2 "Temp2/CPU" set temp2_over 65 # I don't really know what temp is too hot... set temp2_hyst 25 ignore temp3

3. Fans

   set fan1_min 0

ignore fan2 # I currently don't have a case fan

set fan2_min 3000 ignore fan3

Elite K7s5a motherboard (taken from HowToK7s5aHOWTO?)

1. This motherboard uses an it87 chip, and needs the following
2. two lines in /etc/modules.conf:
3. alias char-major-89 i2c-dev
4. options it87 temp_type=0x31

1. For this family of chips the negative voltage equation is different from
2. the lm78. The chip uses two external resistor for scaling but one is
3. tied to a positive reference voltage. See ITE8705/12 datasheet (SIS950
4. data sheet is wrong)
5. Vs = (1 + Rin/Rf) * Vin - (Rin/Rf) * Vref.
6. Vref = 4.096 volts, Vin is voltage measured, Vs is actual voltage.

compute in2 (1 + 1)*@ , @/(1 + 1) compute in3 ((6.8/10)+1)*@ , @/((6.8/10)+1) compute in4 ((30/10) +1)*@ , @/((30/10) +1)

1. The next two are negative voltages (-12 and -5).
2. The following formulas must be used. Unfortunately the datasheet
3. does not give recommendations for Rin, Rf, but we can back into
4. them based on a nominal +2V input to the chip, together with a 4.096V Vref.
5. Formula:
6. actual V = (Vmeasured * (1 + Rin/Rf)) - (Vref * (Rin/Rf))
7. For -12V input use Rin/Rf = 6.68
8. For -5V input use Rin/Rf = 3.33
9. 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 compute in7 ((6.8/10)+1)*@ , @/((6.8/10)+1)

1. Temperature

label temp3 "Processor" set temp3_over 40 set temp3_hyst 20 label temp2 "Mainboard" set temp2_over 45 set temp2_hyst 25 ignore temp1
