sensors, how good are the readings?
Having installed sensors on my SuSe 7.2 desktop with gkrellm as monitoring device I wonder how good the readings are that sensors shows. On sensors there is a reading for VCore1 and Vcore2. The reading for vcore1 lies in between the min max, but the reading for the vcore2 is with 1.5 volts lower as the 1.80 given as minimum. As I have no idea, first what this means :-) and second how good and trustworty this reading is, I would like to lknow if I should be getting nervous ;-). Another info which I do not like that much is that my minus 5 Volt (min -4.5 and max -5.48) lies with -5.72 out of specs. Alarming or ...? Your input/thoughts to above are highly appreciated.

If you are using the default /etc/sensors.conf file for sensors, there is no guarantee that the limits it gives as min/max are correct for your specific hardware. Quote from the FAQ about Sensors: http://www2.lm-sensors.nu/~lm78/cvs/lm_sensors2/doc/FAQ ------------------------------------------------- 3.4A The labels for the voltage and temperature readings in 'sensors' are incorrect! Every motherboard is different. You can customize the labels in the file /etc/sensors.conf. That's why it exists! The default labelling (in lib/chips.c and /etc/sensors.conf) is just a template. 3.4B The min and max for the readings in 'sensors' are incorrect! You can customize them in the file /etc/sensors.conf. See above. -------------------------------------------------- So... dig up your Motherboard manual, or go to the mfg site and look up the specs of your MB. Edit the sensors.conf file and set the min/max values to the ones spec'ed by your MB mfgr. The values that are reported should be fairly accurate. The program polls the output of the hardware health chip, and reports that back in your Terminal window or in gkrellm. Vcor1 is reporting back the CPU voltage. Vcor2 is linked to the +2.5V reading. You are getting something like 0.32V for Vcor2?? This is what I get, but I am not sure what this value is... definitely not a 2.5V output. I have never bothered to go look this up to find out what it is. C.
Thanks for the reminder. Reading and rereading and somewhere along the process you forget some things. But. Having read the sensors.conf for another time I am hopelessly unsure as to where to change the specs for my mainboard. I have a w83781d chip so that part is easily found. After that I do not know further. I have found the min and max settings but although the maker of sensors has a nice and entertaining style in this config, I do not understand a word from his calculations and so on. If I give you the data, could you return me a updated file. Or could you describe the process so clear that I could do it myself? Groetjes On Tuesday 18 December 2001 18:07, you wrote:

Kind of depends on what you want to do. You really shouldn't have to mess with the calculations - at least I cannot see any reason to. Looking at the voltages section (for the w83781d) of the sensors.conf file, you find out that: label in0 "VCore 1" label in1 "VCore 2" label in2 "+3.3V" label in3 "+5V" label in4 "+12V" label in5 "-12V" label in6 "-5V" So, from that information, you know what these values represent. set in0_min vid*0.95 set in0_max vid*1.05 set in1_min vid*0.95 set in1_max vid*1.05 and so on..... all the min/max thing does is calculate a +/- 5% tolerance in the reported value. You can adjust the accepted range here. If you just want to set the ranges to something a bit more in line with yout MB and processor, you need to do a bit of digging. What kind of CPU are you using? What are your BIOS and hardware settings? Are you overclocking? Underclocking? You can get a lot of basic information about temperatures and voltage ranges by just browsing your BIOS screens.... look at what is being reported back to you in the PC Health section of the BIOS. How does that compare to the results you are getting in sensors or gkrellm? Also, have you set up gkrellm correctly? I don't use it, and when I started it up, the default sensor corrections were set to values that put the reported values way out of range. I have to reset most of them back to 1.0 as the multiplier - this may have something to do with the twiddling I did with my .conf file. C.
What brand of sensors are you using, where did you get them, how much did they cost, and were they easy to install? JLK On Tuesday 18 December 2001 04:02, Constant Brouerius van Nidek wrote:
