What is the three-channel in memory

With the release of the Intel Core i7 platform, the three-channel memory technology is born and bred. Like dual-channel memory technology, the advent of three-channel memory technology is mainly to improve the communication bandwidth between memory and processor.

To say three-channel memory technology, we can trace back to dual-channel memory technology. Speaking of dual-channel memory technology, perhaps many people have heard, and even familiar with its principles.

Dual-channel memory technology launched the original purpose is to solve the CPU bus bandwidth and memory bandwidth mismatch between the contradictions, as the FSB increasingly high front-end bus, memory bandwidth is clearly a bottleneck, in such cases, the integration of two memory controllers, each memory controller to control a channel, Allow two of memory to be addressed independently so that the efficiency of the memory can be doubled. The application of this technology, which shortens the data waiting time to 50%, is of great significance to the whole PC system, although it is not effective in all applications, but it can achieve good results in most applications. And with the development of hardware technology, the effect of dual-channel memory technology also began to highlight.

Three-channel memory technology, in fact, can be seen as the follow-up technology development of dual-channel memory technology. The Core i7 processor's three-channel memory technology, the highest support for ddr3-1600 memory, can provide up to 38.4gb/s high bandwidth, compared with the current mainstream dual-channel memory 20gb/s bandwidth, performance improvement can almost double the effect.
