Sensors configuration for Asus P5PE-VM motherboard

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I wish to share this configuration if Jean or somebody else could verify what I have done so far and add this to the wiki.

Here's the default sensors output (only the unconfigured inputs are shown):

$ sensors -u
in1:
  in1_input: 1.856
  in1_min: 2.040
  in1_max: 1.712
  in1_alarm: 1.000
in4:
  in4_input: 1.648
  in4_min: 1.520
  in4_max: 1.680
  in4_alarm: 0.000
in5:
  in5_input: 1.632
  in5_min: 1.488
  in5_max: 1.648
  in5_alarm: 0.000
in6:
  in6_input: 0.184
  in6_min: 1.976
  in6_max: 1.520
  in6_alarm: 1.000
in9:
  in9_input: 0.184
  in9_min: 1.248
  in9_max: 0.872
  in9_alarm: 1.000

For the +12V scaling:

+12V BIOS samples: 12.196, 12.249, 12.302

12.249 - 12.196 = 0.053
12.302 - 12.249 = 0.053

12.249 / (1+56/10) = 1.855909091

1.855909091 is close enough to in1 (1.856)


To verify the scaling factor:


231 * 0.008 * (1+56/10) = 12.1968
232 * 0.008 * (1+56/10) = 12.2496
233 * 0.008 * (1+56/10) = 12.3024

and it almost matches exactly to each BIOS samples. The compute statement for +12V scaling is:

compute  in1  @*(1+56/10), @/(1+56/10)



For the +5V scaling:


+5V BIOS samples: 5.094, 5.145, 5.171, 5.196

5.145 - 5.094 = 0.051
5.171 - 5.145 = 0.026
5.196 - 5.171 = 0.025

(5.196 - 5.094) / (2 + 1 + 1) = 0.0255

5.196 / (255/80) = 1.630117647

1.614117647 is close enough to in5 (1.632)

But when I tried to verify the scaling factor:

202 * 0.008 * (255/80) = 5.151
203 * 0.008 * (255/80) = 5.1765
204 * 0.008 * (255/80) = 5.202

So I'm not so sure if this is acceptable. If I made a mistake from my above calculations please let me know. The compute statement for +5V scaling is:


compute  in5  @*(255/80), @/(255/80)


And this is the entire configuration:

### Comments are welcome.


chip "w83627ehf-*"


### Voltages

   label  in1  "+12V"
   ignore in4          # ignored (not used?)
   label  in5  "+5V"
   ignore in6          # ignore these
   ignore in9          # as well (not used)
   ignore cpu0_vid     # Always at 0 in my case, so ignore it

   ### Scale +5V and +12V.

   compute  in5  @*(255/8), @/(255/80)
   compute  in1  @*(1+56/10), @/(1+56/10)

   ### Set in0 according to CPU nominal voltage.

   set in0_min   1.2000
   set in0_max   1.3375
   set in5_min   5 * 0.95
   set in5_max   5 * 1.05
   set in1_min  12 * 0.95
   set in1_max  12 * 1.05

### Temperatures

   # temp3 is unidentified

   label  temp1  "M/B Temp"
   label  temp2  "CPU Temp"

   ### Set according to preference.

   set temp1_max      60
   set temp1_max_hyst 55
   set temp2_max      60
   set temp2_max_hyst 55

### Fans

   ### Ignore fan3 and fan5. There are
   ### only 2 fan connectors on this board.
   ### fan4 is missing.

   label  fan1  "CHA Fan"
   label  fan2  "CPU Fan"
   ignore fan3
   ignore fan5

   ### Set according to preference.

   set fan1_min 0
   set fan2_min 900
