Since I got my EEE PC i tried to figure out how to overclock it.
Why?
Because Asus’ earlier announcements said it would run with 900mhz.
But my eeepc (like almost any other) runs with 630mhz. It is downclocked, probably for saving energy (which is useless if you look at some documentations about overclocking the eee).
Anyway, I used a script (from this Howto) for overclocking it step by step. I experienced kernel desyncs, vga failures etc.
Now, before coming to the solution, I’ll explain some basics:
The eee.ko module is needed, which gives you access to some hardware functions like fan_speed adjustment (which I use for the eeepc-fancontrol) AND the fsb.
You can find the fsb (after modprobing the eee module) at /proc/eee/fsb . Normal contents are:
70 24 0
The first number is your current frontsidebus frequency in Mhz, i forgot the second one, and finally (important!) the magic value for voltage. This value must be set to 1 if you experience problems while overclocking. Took me ages to associate this with the fsb script and my issue.
Note: As said at #eeepc @ freenode: Setting the third value to 1 can help with SDHC issues (connects-disconnects etc.)
I noticed the script, which i use to set the fsb never sets the magic value to 1, so i dont have to wonder my eee always freezes.
The Modified fsb script can be downloaded here.
Attention: I am not responsible for ANY damage you do to your hardware/software by using this script!
Update: I repaired the link so this fsb script is available again
