cpufreq Celeron 550 2.0GHz on Hardy

[m-a-c]

Hi!
I have an Acer TravelMate 5320 laptop with Intel Celeron 550 on 2.0 GHz and cpu scalling just won't work. I tried to load many modules but none of them doesn't work. Please help...Thanks!

I don't believe the Celeron processors support frequency scaling. I had a Celeron M 430 1.73GHz in my previous laptop and it did not support frequency scaling.

While I'm not certain about the Celerons, I can say that on my G5 PPC box, the default powernowd doesn't seem to work, so I uninstalled it and installed cpudyn instead as a replacement. Scaling works for me now..

Here is a list from my experience of processors that support frequency scaling on the fly.

Athlon 64 (all makes)
Pentium D
Core Solo
Core Duo
Core 2 Duo

There may be more.

Does that include Opterons? (On the Desktop)

I cannot say, the list of processors I have are ones that I have actually used. I have never used an Opteron.

Easiest way is to boot up a LiveCD on an Opteron machine and se if it does.

Frequency scaling works on Celeron if you add "p4_clockmod" to your /etc/modules file.

I've tried that and it doesn't work...
Any more ideas?

I think celeron doesn't support spufreq. I looked at http://processorfinder.intel.com/det...px?sSpec=SLA2E and also at Intel Celeron M Processor on 65 nm process datasheet, page 23, all other fields are marked RESERVED so it looks like it doesn't support it
