View Full Version : [ubuntu] AMD A6-3400m turbo-core not working

I couldn't figure out why the Flash video performance was almost equal to my previous 4 year old computer. Then I checked if in fact my CPU scaled properly - unfortunately not:

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
1400000 1300000 1200000 1100000 1000000 900000 800000

2300000 is missing.

I've tried the latest daily kernel snapshot and that doesn't help. Does any one have any other fix?

From my online research I am going to assume that the Turbo boost is working, but it's just not being listed.

I have the same problem on my A6-3420M. Though when I use the frequency scaling applet in GNOME, the CPU also only goes up to 1.5 GHz. How can this be fixed?
