Wrong values could be caused by the fact, that your system uses a very high
Stopwatch.Frequency (actually this seems to be the TSC of the CPU itself).
Maybe the
EstimateMaxClock should use a start time offset of "ticks" or "ticks / 2",
instead of
just "2". Otherwise the "timeEnd - timeBegin" is longer than the intervall
counted
with the TSC. But this would just explain values that are too small, and yours
is too
high.
Does OHM always estimate about 3312 Mhz? What is the range of values (lowest,
highest) you can get from OHM? You need to start OHM a few times, because the
Frequency is estimated only during startup for Pentium 4 CPUs.

I dont know what happened but right now i downloaded the same version from
site, and
problem disappeared, i cant repeat wrong result, rebooting three times, run
program
five times and get always the same 3015cpu 201bus. Did you change something in
program?
I dont understand tech stuff what you saying to me, i just noticed this strange
thing
and decided write a bug report for helping improve the app. This is not
important for
me. and for many other i think, because P4 is realy old CPU.
But if some more info needed you can ask me
PS BIOS at default settings of course

The technical details above are mostly a note to myself, so you easily ignore
them.
Thank you very much for testing this once more (and giving feedback on the
issue).
I did not change anything in the OHM so far. The OHM does only estimate the cpu
and
bus frequency, and it can occur in rare cases that the estimated value is not
very
accurate. But its good to know that there can still be cases where the accuracy
is
not as good as I expected. And I guess this is not limited to P4 CPUs.
So it could be useful to improve the clock estimation routine further.
