"Intel i5 and i7 chips, even when overclocked properly through the BIOS
or UEFI interface, will not report the correct clock frequency to
acpi_cpufreq and most other utilities. This will result in excessive
messages in dmesg about delays unless the module acpi_cpufreq is
unloaded and blacklisted. The only tool known to correctly read the
clock speed of these overclocked chips under Linux is i7z."

http://code.google.com/p/i7z/ might already be packaged for your distro,
or that page gives executables as well as source. As for what you have
to do with it after that, I've no idea. Slow and steady wins the race.

Cheers, Ralph.
