During its development stages, the Dual Channel mode was improved and the requirements for modules were modified as well. The Dual Channel mode is activated by the system one by one for each memory channel if you insert two identical DIMMs as follows:.

Please note : Configurations that do not fulfil these requirements, automatically work in Single Channel mode. The Dual Channel Interleaved mode provides the highest performance. It is activated whenever the particular total capacity of the built-in modules is identical in both channels. However, it is important that the total capacity of channel A and channel B is identical — a requirement that can be met with two, three or four DIMMs.

The Single mode is activated when the particular total capacity of the built-in modules differs in both channels. Computer memory controllers may be categorized by the number of communication channels it supports. A single-channel memory, for instance, has one channel, while a triple-channel has three. The most number of channels RAM can have is eight. Many people mistakenly refer to dual-channel memory as multi-channel memory. The two channels on dual-channel RAM allow the reading and writing into the memory on remote channels.

DDR or Double Data Rate refers to the rate at which the data is written to memory and not the number of memory channels. Some memory controllers offer more than one channel for the module to communicate with the CPU, boosting data exchange rates. In essence, if a computer has one stick of RAM of multiple sticks of different configurations, it can only run one channel of communication between the memory and the CPU.

This feature is automatically enabled in most motherboards today when two RAM sticks with identical configurations are installed. The original dual-channel architecture design combined two separate bit buses into a single bit bus. This was later dubbed the ganged model. While the performance increase was apparent after combining the two buses, the boost was not enough.

Manufacturers discovered that a CPU performs better when two independent buses are used to transfer the data. We also use third-party cookies that help us analyze and understand how you use this website.
