Intel Atom D510 power management

I have opensuse 11.2, updated…

The problem is that the processor, Atom D510 always runs at 1.66GHz and the frequency is not dynamic. I read on the net that some runs at 800MHz or 1.33GHz based on load

powersave -l

Hi
Do you have the package called ‘cpufrequtils’ installed? With this you
can change the settings. Not sure what desktop your using, but there
maybe some GUI tool too… There are three commands, cpufreq-info,
cpufreq-selector and cpufreq-set.

wrong, unknown or unhandled CPU?

I’ve figured it out… Atom D510 doesn’t have SpeedStep technology

Just to avoid someone else searching so long: Intel Atom D410 has not speed steps ether, see Intel® Atom™ Processor D410 (512K Cache, 1.66 GHz) with SPEC Code(s) SLBMH
