We assembled the computer or upgrade the memory, found that there are four memory slots on the motherboard, do not know which memory slot can be plugged in, in fact, in theory, any plug to which memory slot can be used frequently, but any cap, not necessarily to form a dual-channel, and the formation of dual-channel is also a matter of concern.
So what does dual-channel memory mean? How do I install it? The following is general knowledge of memory dual-channel and attached to the formation of memory dual-channel correct plugging tutorial; I hope this article can help you.

1.What does dual-channel memory mean? What’s in it for you?
We know that if a motherboard supports dual memory channels, it means that the motherboard’s northbridge chip is designed with two memory controllers. These two memory controllers can work independently of each other; each memory controller controls one memory channel so that the CPU can address the two memories separately, can bring double the memory bandwidth for the computer, provide higher data bandwidth for the CPU, the software for frequent exchange of memory data gets a significant advantage, thus improving the speed of memory feedback information to the CPU.
For a simple example, we know that the data transfer between CPU and memory comes and goes. A single channel of memory is equivalent to having only one road divided into left and right lanes, one lane is solely responsible for going, and the other path is responsible for going back. Still, because the road (bandwidth) is relatively narrow, so the traffic flow is not very large.
And the two-channel memory is equivalent to one more road, in two ways, so that one path is responsible for going and the other is responsible for going back so that the road (bandwidth) doubles and the natural traffic is also higher.
The performance of dual-channel computers has improved, especially in nuclear display computers, such as AMD’s APU platform. It’s a doubling of bandwidth, but not a doubling of computer performance, so for our daily use, memory dual-channel isn’t very noticeable, or even perceptible.
2.Conditions for the formation of dual-channel memory
Motherboards need to support dual channels, and all motherboards nowadays support dual channels, so people don’t have to worry. Two or more memory sticks are required to support dual channels, which cannot be achieved with a single memory stick.
Finally, we’ll see how to plug in the memory to be dual-channel memory.
3.the formation of memory dual-channel correct insertion method tutorial.
If the motherboard provides two memory slots, then there is no doubt that two full memory slots can form a dual channel. If the motherboard provides four memory slots, then we need to pay attention to it. To make it easier for everyone to understand, we have numbered the memory slots, the memory slots closest to the CPU are numbered in the order of 1, 2, 3, 4 slots, as shown below.
We only need to insert the memory into the number “1, and 3 memory slots” or “2 and 4 memory slots” to complete the formation of the dual memory channel, from the priority suggested priority 2 and 4 memory slots, followed by 1 and 3 memory slots the 2 and 4 memory slots priority is the most significant advantage of avoiding the tower CPU cooler.
In the case of 1 memory, it is inserted in slot #2, single-channel memory.
In the case of 2 memory, priority is inserted in slots 2 and 4, followed by slots 1 and 3, completing the formation of dual-channel memory.
In the case of 3 memory, insert in slots 2 and 4. At the same time, the third one is arbitrary, and it is recommended to insert in slot 3 to avoid the tower CPU cooler blocking, completing the formation of dual-channel memory.
In the case of 4 memory, plug in full, complete the formation of dual-channel memory.
Wrong memory insertion.
In the case of 2 memory, insert slots 1 and 2 or 3 and 4 for a single channel.
4. Frequently asked questions.
Do I need to set up dual memory channels?
A: There is no need to set it up; just follow the above method to insert the right memory.
Does the dual-channel memory capacity have to be the same?
A: Memory capacity can vary, for example, DDR4 4G + DDR4 8G memory.
Does dual-channel memory have to be the same brand?
A: Memory strips cannot be the same brand.
Can dual-channel memory be different frequencies?
A: Dual-channel memory can be at different frequencies. Still, the highest frequency memory will automatically drop to the lowest rate, and various timing memory can also form dual-channel but must be the same generation, such as DDR4.
Its dual-channel memory a game boost?
In general, there is a difference between dual-channel memory and single-channel memory. However, depending on the game, some games still have a clear advantage over dual-channel memory, mainly in terms of frame rate improvement.
