The Asus Eee PC 1101HA 11.6 inch laptop gives users more control over the clock speed of the Intel Atom Z520 CPU than any other Eee PC model. Not only can users adjust the clock speed using the Super Hybrid Engine in Windows, but there’s a BIOS setting that lets you tweak the overclock value from between 15% and 32%.
But it turns out there’s a catch: If you upgrade the computer’s RAM from 1GB to 2GB, you lose the ability to alter the overclock value in the BIOS. Apparently the same thing happens if you update the computer’s BIOS to the latest version.
It’s not clear at the moment whether the BIOS overclocking setting was an experimental feature that Asus wants to phase out, or if there are just a few glitches that need to be worked out.
