What does it mean to support memory dual channels?

1, Memory dual channel what is the meaning?

The so-called dual channel is definitely two channels, this is the two memory size of the same brand of memory to be reconstituted together memory mode. And one memory is a single channel, and two memory is two memory controller to control two memory respectively. This is better than a single channel in performance, but the specific situation to be specific analysis.

2, the benefits of dual-channel memory:

But memory has only one memory controller, and dual memory has 2 memory directors, theoretically increasing the memory bandwidth by one times. and dual channel is two independent, has the complementary energy can only memory controller, is two memory controller in the normal situation all is the colleague work, if needs the complementary words also is mutually coordinated, each other. That is, a single channel memory is 1 time times more readable than dual-channel memory when reading access memory. That is, dual-channel and single-channel in memory reading is the same. Only two channels save half the memory read time than single channel memory. This speeds up the normal reading operation of the computer.

3, how to component memory dual channel?

When it comes to building memory dual channels, it is actually inserting two of the same size with the brand memory can be set up good channel memory. Why is it the same size and the same brand? That's because two memory compatibility can be considered. If you can not concurrently two memory, then there will be computer boot detect memory, can not start the machine failure. Of course, we found the location on the motherboard on the slot on the bad memory and plugged in two memory. The computer can be compatible with good, normally can boot, and then you download the Cpu-z tool to detect computer configuration parameters. Then check to see if the computer is in a dual-channel state.

User feedback:

Some netizens to the small part of the question that the computer motherboard memory slot has 4 slots, then can support four channels it? So the performance is not stronger? Then there is little motherboard support for four channels. So for 3 channels and 4 channels, it is recommended not to try. Just as understanding can be.

Another netizen asked a small set if two 2G memory card will be better than a 4G effect performance? In fact, 2 with the brand specifications 2GB memory set up dual-channel 4G memory, its performance is superior to a 4GB memory performance. But in the dual channel when the compatibility can also be considered, so there is a negative effect.
