RAM is responsible for the loading speed of applications and affects their work. Its speed can be increased without even buying a new expensive kit. To do this, you need to put it in two-channel mode. How to do it – in this article.
What is Dual Channel Mode
Dual channel mode means that two memory channels will work in parallel. This is one of the most common multichannel memory modes. It improves the performance of your PC by increasing the number of communication channels between the dies and the memory controller in the processor.
Criteria for dual channel operation
The most common question: is it possible to install RAM of different sizes in a computer? The answer is yes, you can, while it will work stably. BUT, 2-channel mode will not work with this setting.
The average user will not notice the difference, but for those who work with demanding programs and like to sit in heavy games, this is a significant disadvantage. Tests confirm this.
Dual Channel – two-channel mode.
Single Channel – single channel mode.
Detailed tests in games can be viewed here:
You can also install modules with different frequencies and timings, but they will work with the characteristics of a less productive bar. There are no problems with dual channel mode with this configuration.
The manufacturer of the memory does not matter if all the previous nuances have been taken into account. It is desirable that all strips have the same chip manufacturers, otherwise compatibility problems may arise. If one of the bars contains Samsung chips, then the other must also contain Samsung chips.
The exact information about which chips are used in a particular model can be found on the website of the manufacturer of memory dies.
Thus, strips with different volumes or different chip manufacturers will not work in dual-channel mode; in all other cases, you just need to correctly insert the modules into the motherboard.

How to set up dual channel mode
To use multichannel memory mode, the processor must have a controller that supports this function, and the motherboard must support this architecture. In addition, it is desirable that the memory chips are from the same manufacturer, otherwise the system may simply not start.
Let’s start installing the memory. In motherboards with four slots for RAM, the channels are usually distributed as follows: each pair of connectors has its own channel.
In this case, if you have only one RAM module, wherever it is, the memory will always work in single-channel mode. If there are two modules, then, if installed incorrectly, communication with the processor will either be carried out in single-channel mode, or there will be a black screen altogether, since the motherboard will begin to swear at the incorrect installation.
In order for the dual-channel mode to work, in most cases the RAM should be inserted into slots A2 and B2 if you have two modules, or into all four slots if there are four modules.
In some cases, manufacturers distribute communication channels differently, therefore, before installation, it is better to look at the documentation for the motherboard.
If the motherboard has only two slots for RAM, then you should insert the modules either into both slots, or into the B1 slot.
Sometimes motherboard manufacturers paint the slots in different colors. In most cases, slots are colored through one:
Usually, the slots where you need to insert modules to obtain dual-channel mode are very bright and immediately attract attention so that the user does not confuse anything. There are exceptions where the manufacturer decides to do the opposite, so, again, it’s worth reading the documentation. In addition to it, you can be guided by the marking of the slots, which is applied next to it.
Less common are the options when the manufacturer paints the slots via communication channels. That is, A1 and A2 slots are colored, for example, in red, since one channel approaches them, and B1 and B2 – in purple, because information is transmitted from them through another channel.
Speaking of motherboard documentation. Usually, in manuals, slots are signed according to the following scheme: form factor + slot name, for example, DIMM_A2. Only recommended options for installing modules in the motherboard are indicated here. In order not to get confused in the name and order of the slots, you need to compare the images from the documentation with the markings on the motherboard.
After the performed operations, you can enter the CPU-Z program to check if the dual-channel mode has turned on. To do this, after installing the program, you need to go to the Memory tab, in the “Channel #” line it will be written in which mode the modules are working now:
Single – one-channel or Dual – two-channel.
Thus, dual channel RAM is a very cool thing that speeds up your computer a lot. Moreover, for its implementation, you do not need to rack your brains with complex schemes and a wallet – with big expenses. It is enough either to rearrange the memory modules, or to buy a bar in addition, which will not be so expensive, but it will greatly improve your experience of using a PC.
