Athlon not running at full speed?
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

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 ;-) Andreas -- Andreas Jaeger, aj@suse.de, http://www.suse.de/~aj SUSE Linux AG, Maxfeldstr. 5, 90409 Nürnberg, Germany GPG fingerprint = 93A3 365E CE47 B889 DF7F FED1 389A 563C C272 A126

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. You can test it with while true ; do true ; done in a shell. This is done to keep your electricity bill low. -Andi

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

If I run SETI@Home on my Athlon64 3200+ CPU speed is always at 2.0GHz... The system only goes down to 800 if it is _really_ idle. Running something like SETI means that there is work to do and therefore it should speed up automatically. Running at 800MHz is a feature, not a bug ;) Andy

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 gives me: cygnia@cygniapolis:~> powersave -r 18426217103360.000000 MHz That doesn't look right, does it? I'm not sure how to interpret a number like that, or maybe I'm reading it wrong. -- Bryce Hardy (Santa Rosa, CA USA) cygnia@sonic.net

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.
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?;-) Moritz -- NEU: GMX ProMail mit bestem Virenschutz http://www.gmx.net/de/go/mail +++ Empfehlung der Redaktion +++ Internet Professionell 10/04 +++
