E6550 processor clock control -- which module?


Hi,

I have an ubuntu 7.10 box with E6550 dual-core processor. Which module do I need to control the cpufreq? Currently it reports

Code:
siim@Shiva:~$ cpufreq-info 
cpufrequtils 002: cpufreq-info (C) Dominik Brodowski 2004-2006
Report errors and bugs to linux@brodo.de, please.
analyzing CPU 0:
  no or unknown cpufreq driver is active on this CPU
analyzing CPU 1:
  no or unknown cpufreq driver is active on this CPU
I have tried acpi-cpufreq, speedstep-centrino and p4-clockmod without any success. The kernel is

Code:
siim@Shiva:~$ uname -a

Just curious but did you turn the option on in your bios? I think mine shipped off by default. Also for the core duo processors it should be using speedstep-centrino. Does it actually know what kind of processor you have?

Bingo! Yes, it was disabled in bios.

However, it seems not without a reason. Now I seem to be locked into the 600-700MHz cage where I cannot throttle the cpu over 700MHz. There are posts on this topic, the problem seems to be related to bios itself.

This is an nVidia mainboard, I will report details later.

Best,
Ott
