The title seems to be written by a person with dual personality!
But as more vitamin and overclocking, and that's fine, but then I talk about underclocked?
Yes, although it seems a contradiction in fact make sense either.
The eeepc is on average well to do everything you need, but sometimes it seems slow, it lacks that touch of panache that could solve some unforeseen situation ... it comes with skype, browsing, while referring to a document ... well poor CPU may not be reactive, and then switch to a higher clock can help.
Or are they on the plane, and I want to enjoy a good movie, and here the power is not needed, it is indeed too well but the battery is known, is never enough and then you go down the clock to save some power.
At this point the question arises: how?
Let's start, the Eee PC as the processor has an Intel Celeron M 900MHz, but is "castrated" to 630Mhz this means that there 'ability to change the clock frequency, with simple software changes, no screwdrivers or circular saws 
I will explain how to operate on a Mandriva Linux distribution, but conceptually the same for all distributions, and for Windows there are programs that do an even easier.
Conceptually, to vary the frequency of work just to add a kernel module that allows you to change the frequency of the Front Side Bus (FSB) and to submit these changes every time the kernel is updated.
Do not you understand anything? Or, it sounds a little complicated and inconvenient?
You are right! It all boils down to install the dkms-eeepc-linux-0.2-3dj.noarch.rpm that contains the converted as a kernel module dkms (Dynamic Kernel Module Support).
The system dkms will make the problem independent of the kernel updates, simplifying and making everything very comfortable.
Without the change, to increase the frequency you need to write (as root) the following commands:
80 24 echo 1> / proc / eee / fsb
90 24 echo 1> / proc / eee / fsb
echo 100 24 1> / proc / eee / fsb
My suggestion is to vary the speed gradually to avoid making the system unstable, from a speed of 70Mhz FSB wearing it in this way to 80, then 90 and finally to 100MHz.
Of course you can do the opposite and "play" to seek the lowest possible rate, keeping the system stable.
If you put the commands in a script, put a sleep for a couple of seconds between a change in the other.
Unfortunately there is no 'way to know if the current rate by:
cat / proc / eee / fsb
which of course will return but not the frequency of the FSB of the processor.
While cat / proc / cpuinfo will always return 630Mhz.
NOTE
Change the frequency, especially raising it, could cause damage all'eeepc because you do work outside of standard parameters.
The temperature will be higher of course, so be careful.
I am not responsible for your own mess! 
Personally, since I have the eeepc, varying the frequency as needed, keeping it up for several hours without ever having had a problem.
