While cpufreq works, it only offers support for the lowest possible frequency (1596MHz) (Linux mhcln01 2.6.19-rc1-git5-mh02 #3 SMP Tue Oct 10 01:35:05 CEST 2006 i686 GNU/Linux ) root@mhcln01:../system/cpu/cpu0/cpufreq >cat scaling_available_frequencies=20 2394000 2394000 2394000 2394000 2394000 2394000 2394000 2394000 2394000 1596000=20 As I understand it, the command above should list all possible "steps" for this CPU. The E6600 supports a multiplicator change between 6 and 9. For a default FSB of 266 this would mean the valid steps for the CPU are: 2394000 2128000 1862000 1596000=20 There is another thing bugging me with cpufreq: +root@mhcln01:../system/cpu/cpu0/cpufreq >cat scaling_cur_freq=20 1596000 +root@mhcln01:../system/cpu/cpu0/cpufreq >cat cpuinfo_cur_freq=20 1596000 Since the machine is overclocked to FSB301 (2.7GHz), the output above is clearly wrong (should read 6 x 301 =3D 1806MHz). I wonder if it would be possible to replace the output with the real frequency, not some hard-wired frequency/vcore value?
