How do I go about finding compatible RAM upgrades?

When purchasing RAM for your system, it pays to know what your system is capable of using and what configurations are possible, so always refer to your motherboard manual for information regarding compatible RAM.

Of key importance with RAM upgrades is that you match as closely as possible what is already installed in your system in terms of memory speed, or replace all RAM in the system with the same kind.
While it is not vitally important that you install identical RAM (though it is recommended), installing matched pairs of RAM in individual memory channels is required so as to not break dual-channel support.

Note: When upgrading RAM from 2GB to 4GB, you may not get what you expect. Here is why.

You can research and purchase RAM online at any number of websites.
