Problem: What Dual Channeling, and Triple Channeling really are and how they work. This will require more than "two can do the job better than one" because that's not true of unmatched RAM. So, take the time to read and understand what these technologies are and how they work. Then take a look at the different DDR/PC speeds and explain how they affect performance, whether they need to be matched, and how to determine the right kind of upgrade for a given system.
