Memory is one of the most critical system components in any computer. It is RAM that has allowed computers in the past and present to operate at such snappy speeds. You can picture RAM as one big buffer used to store any data temporarily for ultra fast access from the CPU (Central Processing Unit) or other components, allowing such component to go about its business with minimal delay.

Like most questions of this nature there is no simple "yes" or "no" answer that will apply to everyone. First things first, users need to know why Corsair among other memory manufacturers and vendors offer the more expensive type of memory and what it does.
