I can absolutely verify and confirm that I get the same results as
everyone in this thread:

Whether or not the CPU is running at 3.0GHz or is overclocked to 3.6GHz,
the reported speed always remains 3.0Ghz.

The output of both dmidecode and by checking the actual processing speed
with any application (bogomips), shows the exact overclocking ratio when
compared to stock - as expected.

While it is only a reporting issue, as the CPU performance is correct -
it does mean that I'm (always) multiplying the actual CPU speeds by 1.2
(3.6/3.0 GHz) for any performance calculations I might be doing.

The probable issue here is that dmidecode is collecting the correct bus
overclocking information from the BIOS, and using that in the
calculations; whereas cpufrequtils is either only collecting the stock
information, or is defaulting to a standardised set of values; if for
some reason the true information is unavailable (BIOS issues?). (ASUS
P5Q Motherboard)

I have to say ... "OPINION" is actually an interesting (and can be quite
useful) project status, however, I can absolutely "CONFIRM" this as an
issue, and am available for any further testing or analysis.
