Just want to chime in here. I have this problem as well. I have had it
on several motherboards, several CPUs, and every version of Ubuntu and
Debian I have had. I am currently on Lubuntu 16.04 with kernel 4.4.0-78
and this issue persists.
My CPU has a stock speed of 3166MHz on a 1333MHz bus.

After following the instructions from the RAM support tech:
- Change CPU bus to 233 from 200
- Change CPU multiplier to restore stock clock (actually a slight overclock)
- Change DRAM voltage from 1.5 to 1.6
- Increase CPU-NB voltage by 0.1V
RecceDG, it would help immensely if you filed a new report via a terminal:

BearTM, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com
I can confirm this bug is still exactly as described in 13.04. I may not
have the latest kernel, but nothing has changed since the last activity
in 2011, so this definitely is still a confirmed bug.

It also affects Debian test.
So it seems an upstream issue.
- If I set the CPU/HT reference clock at 200 MHz with a 16.5 ratio, it reports
properly as 3.3 GHz max
- If I change CPU/HT reference clock to 234 MHz with a 14 ratio it reports the
max frequency as 2.8 GHz eventhough it should be
My Ubuntu affected with this issue too: 10.04 Lucid, kernel 2.6.32-30,
Intel E6600 overclocked from 2.4GHz to 3.4GHz. I have windows XP
installed on the same PC, and frequency scaling/reporting works fine
(for example tools like cpuZ, OCCT, speedFan show correct frequency
values).
Looks like
Confirming this issue and switching status as per comments by others:
the CPU frequency is certainly not a matter of opinion. Also changing it
to affect the kernel, as that is where the problem lies (/proc/cpuinfo
displays incorrect information). It seems to have nothing to do with
frequency
Suffering from this issue since ever I upped the BCLK frequency of my i7
930 -- the reported CPU freq does not reflect the actual Mobo settings
(CPU-Z on Windows does, for instance.)
Also, I'm with BearTM on this one. IMHO, this issue shouldn't be filed
under OPINION but rather under CONFIRMED
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.

confirmed. overclocked intel does not scale down with intel speedstep so
it gets pretty hot with max speed all the time. also it displays the

Just to be clear, on my AMD systems, frequency scaling does work if
Cool'N'Quiet is enabled in the BIOS, however the wrong speeds are

CPU Frequency Scaling Monitor reports incorrect CPU speeds when overclocked
I have experienced this with 2 overclocked processors. The current one
is an Intel E3300, stock is 2.5GHz (200*12.5). I pushed the fsb from 200
to 300, giving 3.75GHz (300*12.5). However, the cpu scaling shows 3.33
2.67 2.13 1.6 GHz. I'm guessing the standard stock speeds it is adhering
to are
