    lm-sensors and Core I7

    Hi all,

    I just bought a Core i7 system and I'd like to have some CPU temperature readouts. I tried using lm-sensors (last version from Jaunty repository) and sensors-detect can't find any sensor.

    What would I need to do in order to have core i7 support into lm-sensors?
    Would I have to build a new debian package with SVN version of lm-sensors?
    If so, is there a nice tutorial demonstrating how to upgrade a ubuntu package to latest SVN version? (I once tried to update jackd package and failed miserably...)

    CPU: Core i7 920
    Motherboard: Asus P6T (not Deluxe edition)
    running Ubuntu 8.10 x86-64 on 2.6.27-9-generic kernel!

    Thanks
    Ric

    Re: lm-sensors and Core I7

    Recently I purchased a p6t deluxe with an i7 920. My lm-sensors does not find any sensors as well. This makes overclocking slightly precarious at best. I assume that the Greater Gods of Ubuntu will fix this shortly, otherwise I will not run my prcessor at full power

    Re: lm-sensors and Core I7

    Hi,

    I have the same problem with Asus P6T Deluxe and i7 920. I am running 64
    bit version of Ubuntu.

    I have followed this guide.

    Here the only thing detected:

    Probing for `Analog Devices ADT7473'... Success!
    (confidence 5, driver `to-be-written')

    Everything else is marked as 'No'. I have full log if needed.

    Regards

    According to this:

    http://www.phoronix.com/scan.php?pag...item&px=NzA2NA

    a new version of lm-sensors is due shortly that will add more supported hardware to the suite.
    regards

    Cool Re: lm-sensors and Core I7

    New hardware support would be nice, I just built a computer with an Asus P6T and Core i7 920 and realized that it knew nothing of the sensors.

    I'm stuck too xDD

    Anybody tested the 3.0.3 version?

    I have a i7 & Asus P6T Deluxe

    Sorry, no sensors were detected.
    Either your sensors are not supported, or they are connected to an
    I2C or SMBus adapter that is not supported. See
    http://www.lm-sensors.org/wiki/FAQ/Chapter3 for further information.
    If you find out what chips are on your board, check
    http://www.lm-sensors.org/wiki/Devices for driver status.

    I installed last lm-sensors from source. (3.1.0)


    Mini HowTo:

    Get last lm-sensors source from web page: http://dl.lm-sensors.org/lm-sensors/...-3.1.0.tar.bz2

    $ tar xzvf lm-sensors-xxx.tar.gz
    $ cd lm-sensors-xxx
    $ sudo make user
    $ sudo make user_install

    After compiling and installing, you can try:

    $ sudo sensors-detect

    In my case the modules to load in /etc/modules:

    coretemp
    w83627ehf force_id=0x8860
    Now you can edit /etc/sensors3.conf for change labels names etc...

    I think the sys temp detected are the cpu temp, and viceversa, the cpu temp detected are the sys temp

    I wish this could help anyone with a Asus P6T and i7

    Sorry for my terrible english ;(

    Re: lm-sensors and Core I7

    I have an i7 and a p6T, and installing 3.1.0 from source did the trick on getting sensors-detect to recognize my hardware.

    btw, if you install bison/flex after running "make user", you have to run "make clean" before re-compiling. That was one issue I ran into.

    Re: lm-sensors and Core I7

    Yeah the cpu temp sensors are working, but I'm getting errors when trying to load the w83627ehf driver. Did you have to do anything special to get it to work?
