    Guess I'm out of luck here, or what?
    it should be k8 as far as I know.

    Yes the Sempron 2600+, is actually a K8 device.

    Everything goes fine until step 5:
    $ echo conservative > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
    bash: /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor: Permission denied
    Any Ideas?

    do the following
    Code:
    sudo -s
    echo conservative > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

    That did it.
    Still getting use to using sudo. I moved from debian to I am use to 'su' to do what I need.

    Re: HOWTO: CPU Frequency Scaling w/ Kernel Module

    Pharcyde,
    I wonder if Step6 should refer to Step3 rather than Step2 (see below).
    Am I wrong ?

    Cheers

    cpufreq_conservative

    cpufreq_powersave
    cpufreq_stats
    cpufreq_userspace
    [Module from Step 2] <--------- Step3 maybe !?

    Thanks proclamar. You are quite right! I will fix this immediately.

    Any GUI to switch configuration ???

    Is there any graphic application to switch among the different freq.scaling config's ?

    "cat xxxxx >/......" is not very practical

    I used to use Kpowersave but it work with cpufreqd and powersaved !

    How can I replace it ?


    Thanks

    Re: HOWTO: CPU Frequency Scaling w/ Kernel Module

    Thanks for the tutorial, seems very helpful, but I'm sad to say that I'm getting stumped.

    I'm running a Sempron 2600+ (slot 757), my BIOS settings say that Cool'n'Quiet is enabled, and there's another CPU setting enabled along the lines of 'CPU stepping'. I've removed Powernowd.

    When I run 'cat /proc/cpuinfo', it reads:
    Code:
    # cat /proc/cpuinfo
    processor       : 0
    vendor_id       : AuthenticAMD
    cpu family      : 15
    model           : 28
    model name      : AMD Sempron(tm) Processor 2600+
    stepping        : 0
    cpu MHz         : 1608.050
    cache size      : 128 KB
    fdiv_bug        : no
    hlt_bug         : no
    f00f_bug        : no
    coma_bug        : no
    fpu             : yes
    fpu_exception   : yes
    cpuid level     : 1
    wp              : yes
    flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext fxsr_opt 3dnowext 3dnow
    bogomips        : 3217.83
    Now, when I try to install the CPU module, I get:
    Code:
    # modprobe powernow-k8
    FATAL: Error inserting powernow_k8 (/lib/modules/2.6.15-26-server/kernel/arch/i386/kernel/cpu/cpufreq/powernow-k8.ko): No such device
    It's the same story for the generic ACPI and the K7. I see that others are having the same issue, same processor.

    Has anyone got the Sempron 2600+ to work? Is there something obvious I'm missing? I guess that I should point out I'm attemtping this is Ubuntu-Server-6.06.

    Thanks
