powernow-k8: Power state transitions not supported

powernow-k8: Power state transitions not supported

[Michael Pophal]

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.

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.

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

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

>> Do You have cpuid in Your kernel?
What does this mean?

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

Thanks for your help!

Regards Mike

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.

See:
