Get CPU frequency WITHOUT cpufreq modules?

Hello,

I'm overclocking my CPU, and in doing so, the motherboard disables Intel Speedstep automatically. This causes the cpufreq-* modules to not load because the frequency scaling "device" is no longer present in the system.

Is there a way to check the actual frequency of the CPU without these modules?
`cat /proc/cpuinfo` only gives me the default speed of the CPU.

Thanks

"/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq" file shows the current frequency on core 0, but it probably needs acpi_cpufreq module to be loaded.

Thanks for the replies.
cpupower monitor did the trick.

I also installed community/powertop to verify and it was also quite helpful (if a little buggy...)

I must have turned on the C1E support in the BIOS because apparently that is the cause for my performance drop.
