First of all i am neither the creator of these nor responsible for any damage done to your hardware
Why to do it?
there is a good boost in games and you can see by yourself, it is also very safe i used it for two hours gaming straight on my school netbook almost every two days.
If you combine it with tiny xp (i now old but that type of hardware is old too)and modded drivers (i will make a topic for them) you can boost your performance to another level (well, it did work for me but i cannot be sure for everybody)
There are two ways of doing this:
1) You can use this little command line tool made by Misiekantos
Norton takes it for virus.
WORK ONLY ON GMA 945
to get it working first you must type: Misiekantos253
then you will get the following

Here 2) The other is a tool called GMA Booster it works on all versions.You select yours when you download(compability for Gma x3100 and x4500 coming soon)

Download
Here just select your version and download it
Remember every time you reboot or return from standby you have to aply the clock again on both of them and if you choose the gma booster you must download a fresh copy every week or donate some money(any amount).
Happy to answer any questions
