I have a system (not a laptop) that has an "AMD Phenom(tm) II X6 1100T Processor", as reported in /proc/cpuinfo. I have been monitoring the CPU speed as reported there and I see that quite often the speed is reported as 800 MHz instead of 3300 MHz. For example, I ran the four commands pretty much one after the other. The speed is changing all the time: [snip] The system is busy when this is run. So I cannot think there are unused CPUs that are made to slow down because they have nothing to do. Especially changing as often as they seem to be changing.
Is this expected behavior?
Yes I believe it is - I think it's AMDs dynamic frequency scaling "Cool'n'Quiet". Funny though, my own AMD Phenom 9500 seems to run four cores at 2.2GHz without change. -- Per Jessen, Zürich (21.6°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
