For Nocona I would suggest using the in kernel ondemand governor. More
details here
http://www.intel.com/cd/ids/developer/asmo-na/eng/dc/xeon/reference/1959
10.htm
And newer versions of the userspace governors should be able to handle
SMP processsors. Earlier versions didn't. Not sure which version of
cpufreqd you are using.
Thanks,
Venki

oh well... cpufreqd has never been able to handle the userspace governor.

after this message cpufreqd should run correctly considering your
server always ac-on and with no battery.
Anyway, as said you're probably better using the ondemand in-kernel
governor to dinamically scale based on cpuload. You can still use
cpufreqd to apply different limits based other parameters :)

If you're having trouble with cpufreqd on SMP systems, try CPUSpeed. It
works perfectly.

Hi there,
I'm new to cpufreqd. Sorry for my wooden English.
I found that cpufreqd can be used in desktop.
Has anybody ever tried cpufreqd in Nocona System?
My Nocona Server has the speedstep functionality,
and can be throttled by acpi-cpufreq.
But it doesn't have the battery like laptops.
I've tried to set the CPU frequency manually, and it works.
Is it possible to use cpufreqd in it?
Any help is appreciated! Thanks in advance!
Best regards,
Zihui
