thanks, jonathan! I found out that I have "cpuspeed" running. when I do something CPU intensive, the higher frequency is being used. bash-3.00$ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Mobile Intel(R) Pentium(R) 4 CPU 3.06GHz stepping : 9 cpu MHz : 3057.131 cache size : 512 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe cid xtpr bogomips : 6045.69 On Sun, 14 Nov 2004 16:22:50 -0600, Jonathan Berry <berryja@xxxxxxxxx> wrote: > Hi Oliver, > > On Sun, 14 Nov 2004 23:07:38 +0100, Oliver Kiessler > > > <oliver.kiessler@xxxxxxxxx> wrote: > > the directory exits. this is what it says: > > > > [root@stmarks cpufreq]# ls > > cpuinfo_cur_freq scaling_available_governors scaling_max_freq > > cpuinfo_max_freq scaling_cur_freq scaling_min_freq > > cpuinfo_min_freq scaling_driver scaling_setspeed > > scaling_available_frequencies scaling_governor > > > > [root@stmarks cpufreq]# cat cpuinfo_cur_freq > > 1599960 > > > > [root@stmarks cpufreq]# cat cpuinfo_max_freq > > 3066590 > > > > [root@stmarks cpufreq]# cat cpuinfo_min_freq > > 1599960 > > > > [root@stmarks cpufreq]# cat scaling_available_frequencies > > 3066590 1599960 > > > > [root@stmarks cpufreq]# cat scaling_available_governors > > userspace performance > > > > [root@stmarks cpufreq]# cat scaling_cur_freq > > 1599960 > > > > [root@stmarks cpufreq]# cat scaling_driver > > speedstep-ich > > > > [root@stmarks cpufreq]# cat scaling_governor > > userspace > > > > [root@stmarks cpufreq]# cat scaling_max_freq > > 3066590 > > > > [root@stmarks cpufreq]# cat scaling_min_freq > > 1599960 > > > > [root@stmarks cpufreq]# cat scaling_setspeed > > 1599960 > > > > regards, > > oliver > > > > Okay, good.
