The Asus Eee PC 901 and 1000H netbooks ship with a Windows utility called the Asus Super Hybrid Engine that lets you overclock your Eee PC to run at 1.7GHz or underclock your machine to run at 1.2GHz rather than the standard 1.6GHz clock speed. This lets you boost your performance or battery, whichever you need more. But if you’re looking for a bit more control, you might want to check out eeectl, a third party utility that gives you far more options for controlling everything from your Eee PC’s clock speed to the fan speed.
First, a word of warning. Eeectl was written for the Eee PC 701, which has a 900MHz Intel Celeron processor. It was not designed for use with Intel Atom-powered machines like the Eee PC 901 and 1000H. But some users have figured out that by adjusting the settings in the eeectl.ini file, you can get decent performance on these machines.
French site Blogeee has posted two modified .ini files, one for the Eee PC 901 and another for the Eee PC 1000H. All you need to do to use them is to download eeectl, unzip it, and open the eeepc.ini file in notepad or a similar text editor. Replace the text with the italicized text from Blogeee.
Before you click on eeectl.exe, make sure to turn off the Asus Super Hybrid Engine. These two apps will not play well together.
I loaded eeectl on my Eee PC 1000H and now have the ability to adjust my clock speed to 1GHz, 1.3GHz, 1.6GHz, 1.8GHz, or 2GHz. If you know what you’re doing, you can adjust the eeectl.ini settings further to give yourself more options. But if you’re not careful, you can cause your PC to crash.
In fact, some users have reported problems when using preconfigured eeectl.ini files as well. If you want to go back to using Super Hybrid Engine after adjusting the speed, it may be enough to simply reset your clock speed ot 1.6GHz and then exit eeectl. But some EeeUser forum members recommend powering down your machine, removing the battery, waiting a while, and then turning it back on with eeectl disabled.
So now that I’ve scared you away from even thinking about using this software, whyy would you want to? Because by underclocking your Eee PC to 1GHz, it’s likely that you can squeeze a bit more life out of the battery. I haven’t run a thorough test, but I wouldn’t be surprised to see an extra 15-20 minutes of battery life on a 6-cell Eee PC 1000H. And by overclocking to 2GHz, you may see a performance boost in some applications (although you’ll also see a reduction in battery life).
While eeectl was originally designed for the Eee PC, this modified version should work with other Intel Atom based machines including the MSI WInd and Lenovo IdeaPad S10. Use at your own risk. (See comment below)
