With today's technology changing so quickly it is very easy to get behind. But when you hear about the fastest memory or CPU you think to yourself, "I have got to have it." Well, in truth, when looking at purchasing DDR based memory, there are a lot of things that you have to take into consideration. I am writing this article due to the fact that I frequently browse hardware forums and sites and one of the more notable questions that comes up all the time is, "What is the fastest memory?" or "What kind of memory should I buy?" People typically reply back and say what the faster modules are, or their opinion of different types of memory. What a lot fail to say are the other interesting points that one needs to know in order to maximize his / her system's performance, and at the same time spend money wisely.
