PPC Process Clock

Pimboli · 09-23-2006, 09:15 AM

My Fedora Core 5 Distribution on my PowerPC G4 shows me in the KInfoCenter that my Processor Clock is currently at 666MHz. Actually, my iBook is able to run at 1.33GHz. Is there any way to change this to the full processor clock? Are there risks (linux doesn't start anymore, hardware gets damages,...) ?

Thank you for your Help,

If you are running a laptop, then it was probably detected that your processor can run in multiple speed modes.

What it is doing is underclocking your processor to save on energy and wear.

If 666 Mhz is not enough to run a certain application, Linux will automatically adjust the clock speed up to your 1.33 Ghz on the fly.

To double check to see if this really is what's going on, type "cpufreq-info" in a terminal. It should say "1.33 Ghz processor running at 666 Mhz" or something similar.
