Hi all!
This issue was written over and over,
and a lot of people, including me, have
more questions. Don't want to crosspost,
cause I think that it is related.
On Celeron M laptop, with cpufreq and
powerd, also with this in rc.conf:
performance_cx_lowest="LOW"
economy_cx_lowest="LOW"
I have C2 and 1400 -> 174 MHz. Should it
be set "LOW" for performance_cpu_freq
and economy_cpu_freq? Battery lasts
for almost 3 hours with no X and exten-
sive cd/modem/hdd work. Temperature is
34-38.
On my amd64 box (754, 1800 MHz), with
Coll'n'Quiet, acpi2 and the same confi-
guration, I have just one C (C1) and
two states (1800 and 800). Usb is com-
piled into kernel. (One poster removed
it and got more steps.) Anyway, the box
is really cool, so it is just a matter
of curiosity. Is there anything, beside
using usb as module, to get more c's
and put frequency down dinamicaly?
And no temp measurement on this nforce3
mobo.
Best regards
Zoran
