Dual Channel Memory
Dual channel memory did not exist in the mainstream marketplace until just a year or two ago. Dual channel memory had long been available in servers and other high end computers, but single channel memory was the only option available to PC users. Now, dual channel memory plays as significant a role in determining system performance as the processor speed.
The use of dual channel memory in PCs became a virtual necessity as processor speeds increased. Today's PC processors are tremendously quick, but only when they have data to process. Think of the processor as a small lawn. In order for the grass to grow, it must be watered. Water is the data that the processor needs to perform. If there is only one sprinkler then the lawn may not receive enough water. Parts of the lawn might grow well while other sections lie fallow and wasted.
Doubling Up with Dual Channel Memory
Dual channel memory is like adding a second sprinkler on the other side of the lawn. With water coming in from two places, it's possible to get the most growth out of the lawn. With data coming in through two channels, the processor can reach its maximum potential.
Simply installing two RAM modules does not insure that a computer is operating in dual channel memory mode. Usually a motherboard will have 3 or 4 sockets for RAM, and the RAM must be installed on two separate channels. On many motherboards, slot one and slot 2 are on the same channel. That means to achieve dual channel memory mode on most motherboards, RAM must be installed in number 1 and number 3, although you should consult your motherboard manual to find out exactly what configuration you need.
