    Please check git version. Make it with debug option.
    Check http://sourceforge.net/p/lfsb/wiki/i2c-SMbus%20availability/
    DO NOT REALY OVERCLOCK !
    Just post output from command
    lfsb ics932s421b
    right here.

    Then my pc locked up and my fan speeds increased. I shut down and on reboot would post. Shutdown again and it booted properly.

    The modules did load and the program did execute but the lockup happened.
    lsmod | grep "i2c"

    Ok, post the output of
    i2cdetect -l

     

  • Fryndr

    Fryndr - 2014-10-07

    bash: i2c-detect: command not found

    I don't understand why it isn't found.

    Here is a locate of i2c:

    You have to install i2c-tools.
    If it debian like try (with root privileges)
    apt-get install i2c-tools

    Ok, sorry for the back and forth.

    Looks good. Now try block read from chip :

    Try new version on git. Build it with debug:
    make debug

    Very good. I'm busy right now.
    The next few days I will make changes to the code.
    Left quite a bit part.
    Can you confirm right FSB calculation ?
    Is this true 133 MHz FSB ?
    Please post output of

    cat /proc/cpuinfo

    I can confirm. Yes 133mhz is correct for FSB. I have 24 cores so I put cpuinfo in an attachment.

     
    cpuinfo.txt

    Andrey Zhornyak - 2014-10-11

    Build new version from git.
    Try to overclock:
    lfsb ics932s421b 133
    Try 133 first, then add some more value.
    Be careful with hi fsb values. It can be dangerous for the equipment.

    I tried it 3 times to be sure. It locks up the PC as soon as I hit yes.

    [fryndr@snowmantle:~]$ sudo modprobe i2c-dev
