Projects / Cpuspeedy


Cpuspeedy allows you to change the clock speed and voltage of CPUs using Linux's CPUFreq driver. It is a user space program, so it will work on every processor supported by the kernel's CPUFreq driver.

    Release Notes: is now checking for every directory in the /proc/acpi/thermal_zone/ directory. If the temperature file is found, then its value is read. This should fix a bug that prevented cpuspeedy from getting the CPU's temperature in those systems where the path to the temperature file is not /proc/acpi/thermal_zone/THRM.

      Release Notes: It is now possible to specify a specific frequency value to be set. The numeric value must be expressed in KHz, MHz, or GHz. An option to display available CPU frequencies was added (--freqs). A check was added to verify the availability of the userspace governor in the pycpufreq sysfs interface. The "--dump" option is working again (a couple of bugs were fixed), and a module was added (
