I am not sure why the kernel is reporting a slower CPU speed than whatyou actually have but perhaps there is some scaling going on? The OS is throttling down the CPU when its idle? I am of course just guessing herebut can you look and see if cpudyn is installed? or a similar software package? http://mnm.uib.es/gallir/cpudyn/faq.html Did the output of of cat /proc/cpuinfo occur right after boot? take a few measurements at different times to confirm the speed. Maybe you can even set it to the right speed by installing cpudyn or similar. Also paste the output of grep -i CPU /boot/config*, it might be useful to see whats going on. -- -----Angelina Carlton-----
Hello Thank you for your reply, i was absent for a while so i didn't noticed it until today.
i have installed cpudyn (i had cpufreqd before) and looked at the faq. i have seen that my kernel didn't have the support for cpufreq.
i don't have anything in : # cat /sys/devices/system/cpu/cpu0/ so i'm going to check my kernel again. the result of my config file : grep -i CPU /boot/config* : CONFIG_X86_CPUID=m CONFIG_APM_CPU_IDLE=y # CPU Frequency scaling CONFIG_CPU_FREQ=y # CONFIG_CPU_FREQ_PROC_INTF is not set CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y # CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set CONFIG_CPU_FREQ_GOV_PERFORMANCE=y CONFIG_CPU_FREQ_GOV_POWERSAVE=y CONFIG_CPU_FREQ_GOV_USERSPACE=y # CONFIG_CPU_FREQ_24_API is not set CONFIG_CPU_FREQ_TABLE=y # CPUFreq processor driversI have recompiled my kernel today with a great care on cpufrequency and i don't understand what is not right.
if you have an idea... I'm pretty sure that this CPU have a speedstep features.Sometime after many test with cpufreqd and some modules (speedstep- smi and speedstep-lib) (who said that it can't do anything) /proc/ cpuinfo was at 230 mhz instead of 500 and the computer was slower than normal. i don't know exactly what action did that.
