No Or Unknown Cpufreq Driver Is Active On This Cpu
update the cache, can anyone remind me what it is?NB: I have an Intel Core2 Duo E7300 CPU, and would like to underclock/undervolt it to get some power savings, as I am running at less than 20% cpu most of the time, even with 720p content. I thought I would do the frequency stuff in the OS and do the undervoltage stuff in the BIOS (unless someone can tell how to undervoltage in the OS).Thanks.

The acpi-cpufreq module offers voltage scaling in addition of frequency scaling. You should use that instead of p4-clockmod, if possible.I had been following that link ..Thanks,B Last edited by bmentink (2010-05-12 02:07:09) Offline #4 2010-05-12 04:07:59 bmentink Member From: New Zealand Registered: 2009-08-23 Posts: 385 Re: cpufrequtils module won't load [SOLVED] An update:I read somewhere that I might need to update my bios to get ptable support for my CPU. So I bit the bullet and did the upgrade ... and guess what .. it now works.I can now modprobe acpi-cpufreq without error and I did a "cpufreq-set -g ondemand" and the ondemand profile is used. However, I notice that when I do a "cpufreq-info" that the current frequency

Accordingly my laptop's cpufreq doesn't run anymore. Until kernel 3.13.8, acpi-cpufreq has been loaded automatically as expected. If I try to load acpi-cpufreq manually on 3.14, # modprobe acpi-cpufreq modprobe: ERROR: could not insert 'acpi_cpufreq': No such device Strangely if p4_clockmod was loaded initially, acpi-cpufreq can be loaded sucessfully too.
