This is a technical problem that has defeated me, so maybe someone could help.
My main, everyday, desktop is a bit old, but it works well now I have replaced the heatsink: it’s using a dual core Pentium D processor, with each core running at 2.67 GHz.
cat /proc/cpuinfo tells me this should support 7 levels of frequency scaling, but I cannot seem to get it to run at anything other than full tilt all the time. I am running Ubuntu 10.10:
adrian@bossclass:~$ uname -a
Linux bossclass 2.6.35-27-generic #48-Ubuntu SMP Tue Feb 22 20:25:29 UTC 2011 i686 GNU/Linux
And I have the
p4_clockmod module loaded. So how I fix this and does the Pentium D even truly support frequency scaling?
