Upgrading the ram in your netbook can be one of the easiest, cheapest and most effective performance boost you can give.
Upgrading your netbook ram can usually be done in a matter of mere minuets, and usually involves simply removing the plastic cover on the base of your netbook and swamping out the old ram module for the new larger capacity module.
Many netbooks only come with 512mb-1GB or RAM, which can slow down the computer when loading many applications, increasing the netbook ram capacity usually provides an instant performance boost, allowing you to run the operating system better along with more applications at once.
You should check your netbook’s manual to find the correct RAM type, but most netbooks, such as the Eee PC range support 667 Mhz DDR2 200-Pin SODIMM.
A large 2GB DDR2 module can be bought for just over $40. I would highly recommend Crucial 2GB 667 Mhz DDR2 200-Pin SODIMM.
