Dear Sirs,

I saw that my Athlon-64 3400+ is running at 800 MHz all the time (at least the Info-Center is telling me this)...

Do I have to switch off apci or how do I set it to full speed? It should be at least 2.2 GHz, or am I wrong?

Thank you, Gery

I had the same problem, had to create a startup script to run : powersave -f that should fix it

Set it in /etc/sysconfig/powersave

I don't understand why powersave -f is needed. You get the cpu power when you need it - and a less noisy system otherwise ;-)

Hi Andreas, thanks for the tip. The system seems much faster now (it never went out of the slower/powersaving-state even when cpu usage was maxed). ...and the system is still silent :) Gery

Just do something that needs CPU power and powersaved will increase the speed automatically.

How would this relate to running something "nice" like a distributed-computing program such as Folding At Home? It's taking four days to process one of the larger work units on my 3200+ system. Is there a good way to speed it up without wasting too much power? -- Bryce Hardy (Santa Rosa, CA USA) cygnia@sonic.net

powersaved currently ignores "nice". It uses the load average, which is independent from it. So your Folding at Home client should always run at full speed. -Andi

I was relying on the output from /proc/cpuinfo, which now I note from the manpage of powersave is sometimes wrong, so I entered powersave -r and it

It shouldn't be on AMD systems. AFAIK the only case where it can be wrong is on a Intel system when your CPU is overheating and goes into thermal throttle. But that shouldn't happen anyways, unless your fan died.

gives me:

cygnia@cygniapolis:~> powersave -r 18426217103360.000000 MHz

It's probably the Hz value. I guess just the printed unit is wrong. The method powersaved uses to measure the performance is not 100% accurate and the hardware is also usually a bit off from the advertised value, so you don't get nice round numbers. -Andi

18426217103360Hz = 18426GHz ?

Where can I buy this 18THz prozessor?;-)

Right I misread it :) -Andi
