However, if your motherboard has the dual-channel feature, then you obviously go for the 2 4 GB RAM stick to get the better bus speed. So, it is better to use 1 8 GB RAM if your motherboard supports single-channel. So, if you add 2 4GB RAM, then two RAMs will use the same path to communicate with the processor and due to excessive traffic, the speed will be reduced. If your motherboard doesn’t support dual-channel, the communication will establish through a single path. In a single channel, the RAM communicates with the CPU through a single path, and in a double channel, the RAM uses two individual paths to establish communication with the CPU.

1. Which Channel Does the Motherboard Support?Ī motherboard can support single-channel, dual-channel, or quad-channel to make communication between the RAM and the processors. If your motherboard has 4 slots, then you can add four 2 GB RAMs to achieve 8GB RAM.īut which one is suitable for your computer and with which option, you can achieve the best performance? Well, it depends on some factors which are discussed here briefly.

You can either add one 8 GB RAM stick or add two 4 GB RAM sticks to your motherboard. If you want to add 8 GB of RAM to your computer, then there are three options in your hand depending on the available slots on the motherboard. 1 8GB RAM or 2 4GB RAM – Which One Is Better Depends on Some Factors?

How fast the program will respond completely depends on how fast the RAM can communicate with the CPU. RAM stores data of programs temporarily on its memory and when you run the program on your computer, it delivers the stored data quickly to the processor. Before going any further, it is necessary to learn how RAM works on a computer and if you know this, it will be clear to you why multiple RAM is better than a single RAM.
