Hi there! Since a few days I've got a new AMD Athlon 64 3200+ System and I have installed SuSE 9.1. Nearly everthing works perfect, but the system runs only with 800 MHz (!?!?) CPU clockrate.

That's just fine. The system has nothing to do - and is so bored that it sleeps ;-). The AMD64 cpus are capable of dynamic power scaling and we use powersaved to change this.

so for the calculation your machine is only running with 19.5 (+3.3), that does not speed it up. P.J. -- ---------------------------- Peter-Josef Meisch Mail: pjmeisch@web.de ----------------------------

OK, now I understand, that's just boosted my laptop from 800 Mhz to 1800 Mhz, now I can turn the wick down again. Regards Sid. -- Sid Boyce .... Hamradio G3VBV and keen Flyer Linux Only Shop.
Hi, how is it possible to activate the power-saving functions on an athlon64 with suse 9.1? after installation my cpu runs all time at 2000mhz. I want to decrease the frequency to the 800mhz in powersaving mode like it was explained before with automatically frequency control when load is there. "powersave" is saying that speed stepping is not supported. Cool and quiet is activated in bios and it works when system is booted with windows. Other Question: Is that a real cool and quiet support? In Windows with cpu drivers from amd also the vcore is decreased. Is there a possibility in linux to do this or is it only possible to throttle the frequency? Thanks! Thomas

When it is supported it will work automatically. If not it is likely a BIOS problem that prevents the cpufreq driver from running properly. C'n'Q needs BIOS support. Consider a BIOS update.
Is that a real cool and quiet support? In Windows with cpu drivers from amd also the vcore is decreased. Is there a possibility in linux to do this or is it only possible to throttle the frequency?
The driver is able to change the voltage too; details depends on what the BIOS allows. -Andi

Check /var/log/messages and /var/log/boot.log. It might be that your BIOS is broken and does not contain the needed information (and windows gets them in a different way).

Both cpu and vcore are decreased, 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

Actually the 9.1 gets it in the same way as Windows now. (first over ACPI and only if that fails over the PST table) -Andi

Makes me wonder if the CPU temp is causing this. I have nothing under /sys/devices/system/cpu/cpu0/ for the XP2800+ as cpufreqd is not installed, I don't know if it is for laptops only.
