Hi there! I have a problem that seems to be serious:
I have a Fujitsu Siemens A1630 notebook with a AMD Athlon 64 3700+ that
works at the frequency of 2400MHz. The problem is: every operating
system recognizes it running at 800MHz, no differences between Vista or
Ubuntu, they simply show only 800MHz. I made a search and I found the
problem could be solved modifying some parameters in the BIOS, I tried
to do so, but unfortunately the BIOS installed on my machine allows me
to manage only a very little amount of settings, and of course, not the
one I was looking for. Can someone help me? And, does the processor
really runs only at 800MHz?

Thanks a lot!

It does if cpu trottling is enabled and it usually is in notebooks by
default. In linux, disable cpufreqd or disable Cool N Quiet in the bios.

To test in linux, type cat /proc/cpuinfo, then open another tty and start
glxgears or some other app that will load the cpu and then cat
/proc/cpuinfo again.

In Linux the CPU speed is controlled by the CPU Speed Governor. The Linux
Kernel provides a number of different governors,
userspace User selectable
ondemand Speed changes dynamically depending on load
performance Fastest available speed
powersave Slowest spped
conservative Like ondemand but it's slower to switch speeds.

If you do a

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors

You will see which governor modules are available for your kernel. I've
only just started playing with Ubuntu (Feisty Fawn, Herd 4) so I don't
know much about what they chose to build. In Feisty Fawn it looks like
only the ondemand governor is there, I don't know if they make the other
governors available. If they don't have the other governors you could
always build your own kernel and select usermode and performance as well
as ondemand. The CPU Frequency Monitor applet will allow you to select a
different governor assuming that there is more than one governor available
(at least you can in FC6, in Feisty Faun the applet didn't have a means of
selecting the governor but I thinks that because they only had ondemand
loaded).

With MS OS, select a power scheme other than minimal power settings
(approximate xlation from French), this should disable Coll & Quiet
