Like other Asus Eee PC series notebooks, the Asus Eee PC 1101HA comes with the company’s Super Hybrid Engine software. This lets you underclock and overclock the CPU to boost performance or prolong battery life depending on your needs at the moment. But there’s one thing that makes the Eee PC 1101HA different – you can tweak a BIOS setting to adjust the overclock values.

For example, if you set the BIOS value to 5%, then when you use the Super Hybrid Engine to overclock your CPU, it will go up by 5%. The values range from 5% to 30%.

There’s just one problem: Most people who have upgraded the RAM in their Eee PC 1101HA laptops from 1GB to 2GB find that it disables the BIOS setting. Well, it turns out that it’s not simply the act of upgrading to 2GB of RAM. Rather, the Super Hybrid Engine only officially supports certain types of RAM. Last time we checked in, there were two approved memory modules. Now there are four:

  • DDRII800 SO-D HYNIX 1GB 200P
  • DDRII800 SO-D A-DATA 1GB 200P
  • DDR2-667 SO-D UNIFOSA 2GB 200P

Using a different RAM module won’t hurt your computer and you should get most of the benefits of a RAM upgrade. You just won’t be able to use the SHE to overclock/underclock your notebook.
