Single Channel vs. Dual Channel vs. Quad Channel RAM

RAM (Random-access Memory) is a form of computer memory (short-term memory). Since it is speedy, RAM makes everything in your computer (like applications or data) run faster. When you turn your power off, this temporary storage goes away.

You will need a certain amount of RAM to play demanding game titles or do heavy tasks with multiple applications. If not, the programs will run slowly or crash.

When you study RAM, you will come across three main types:

  • Single channel

  • Dual channel

  • Quad channel

This article will go into detail explaining the differences among the three of them and some notes when choosing the memory. 

What are the differences between Single Channel vs. Dual Channel vs. Quad Channel RAM?

The name of channels comes from the number of RAM sticks that you insert on motherboards:

  • 1 RAM stick: Single channel

  • 2 RAM sticks: Dual channel

  • 4 RAM sticks: Quad channel

If you install 3 RAM sticks on your motherboard, two will run in dual mode, and the third will run in a single channel. 

For instance, if you install two 16GB RAM sticks to get 32GB RAM, they will be running in dual channel setup. If you install four 8GB to get 32GB RAM, you will be running quad channel configuration. If you install just one large 32GB RAM stick, you’ll be running single channels. 

The main difference between the three types of channels is the level of bandwidth. With the same amount of RAM, dual channel and quad channel may offer double and quadruple the memory bandwidth. The PC will use each stick individually, thereby enhancing the level of bandwidth which will boost the performance.

Single Channel vs. Dual Channel vs. Quad Channel: What should I choose?

For gaming, you may see single channel and dual channel aren’t that different. The games will run at similar frame rates; you will not be able to recognize the difference. Therefore, if your purpose is purely gaming, you can opt for the cheaper option. 

Typically, single channel RAM is less expensive than dual and quad kits. However, you can get great deals and sales on eCommerce stores. If you’re lucky, you can find a dual kit that is reasonably priced. 

Another point to consider is how many slots your motherboard supports and how much RAM you can afford at the moment. If you currently have 8GB RAM and your motherboard has two DIMM slots, it will make sense if you use a single 8GB RAM stick rather than dual 4GB sticks. 

The reason is that it will be more convenient for future upgrades. When you want to get 16GB, you just need to buy another 8GB RAM stick. If you use dual 4GB RAM sticks, you will have to throw them away and buy a new 16GB one. 

The choice of RAM also depends on other factors. Suppose you’re designing 3D models, and you need to render them on your rig. Frame rates will not be a concern in this situation, but CPU performance itself. 

Single channel setups deliver less bandwidth, which causes the processor usage to spike at a rate of 10 to 25 percentage. It means that the CPU with a single channel memory will work harder than it does dual or quad setups. 

Therefore, if you use a weak processor, you may want dual channel or quad channel RAM to avoid the excess load. 

In terms of aesthetics, using two or four sticks of RAM on a motherboard with four DIMM slots will make your build look cleaner. If you’re a person who cares about aesthetics, you may want to fill up your DIMM slots.

At the end of the day, RAM is not the only component that decides your computer’s performance. You need to invest in other parts like CPU or GPU, regardless of your purpose, gaming or design. 

Motherboard limitation

Keep in mind that some motherboards may not be compatible with quad channel configurations. Some CPUs are also incompatible with this type of RAM channel; they will run a quad channel setup as two dual channels. 

Therefore, you should check your motherboard and processor before buying a new RAM kit. You should also consider your purpose to install RAM to get the highest performance.

A final word

Going around online stores, you can recognize that many manufacturers started to adjust the prices to sell more dual and quad channel memory kits. If you have a limited budget, consider differents factors carefully.

The quad channel setup is the ideal option to push your computer performance to its limits, though you hardly notice the difference in gaming. It will be better if you upgrade your CPU and GPU to increase the whole performance.
