powernow-k8: Power state transitions not supported

Hi,
I tried the last 3 days to convince cpufreq to work with my new Semperon 2600+ (Socket 754).
I also bought a new mainboard 'MSI K8T Neo-V'. It is a desktop (not mobile) processor!

I compiled the kernel with the recommended settings. The result during startup:
powernow-k8: Power state transitions not supported

It seems to me, that this processor is not supported by cpufreq, isn't it?

I want to have a cheap processor, which is able to save power, because it is running the whole day. Do you have any recommendation which processor I should use. I'm going to change the Semperon 2600+ to try another combination (cpu + mainboard). Any hint is hightly apprecitated!

Do you have a Semperon xx00+ (Socket 754) running on this 'Cool'n Quiet' mode? Which one works?

Thanks in advance for your assistance!!!

Regards
Mike

As far as I know, Sempron 2600+ for Socket 754 does NOT support C'n'Q.

My dealer told me it does :-(
Can you recommend another CPU, which works with C'nQ? Do you have any experiences?

Do You have cpuid in Your kernel?

I guess it is, however I might be wrong ;)

Do You have "Cool&Quiet" enabled in bios? (I have, I guess similar, mainboard in my desktop, it's MSI K8T Neo2 - there is a bios option that enbles it). When this option is disabled I get similar message ;)
Well, I have another problem with it, desktop with powernow-k8 is not as stable as it ought to be - it hangs hard sometimes (Athlon64 3200+ s939). Problem does not occur in a laptop, where I have Mobile Sempron 2800 s754 working. powernow-k8 is a module, I use powernowd.

Hi Michal,
thanks for your prompt reply.
Yes, I have 'Cool'n Quiet' enable in BIOS.

What does this mean?

What is the difference between powernow-k8 module and powernowd?

Thanks for your help!

That check from cpuid wont work.

The message above (Power state transitions not supported) indicate that cpuid, function 0x80000007 return a value so that the processor do not support frequency and voltage scaling.

You are wrong, I'm afraid.

AFAIK, the only choice is amd64. Maybe ebay would be your friend, who knows?

Actually I'm wrong. The Sempron 3100+ (it seems to be the only one btw) support powernow.
