What is dual channel RAM

Using dual-channel can allow you to get the most out of your hardware and highly increase the data rate between your components and your RAM. Here we reveal to you some useful information and tips about dual-channel RAM memory.

What is dual-channel memory?

Some memory controllers provide a dual-channel for memory. The aim is to use the memory modules in pairs and combine the bandwidth, therefore, maximizing the system's capacity. You should also use identical memory sticks in pairs (in terms of frequency, capacity, and from the same brand if possible).

How to use dual RAM channels?

To use dual channels, you have to get a similar pair of RAM intended for use in your system.
Your motherboard has several RAM channels where your RAM sticks are plugged. Those channels are usually named A1, B1, A2, and B2 (for a motherboard with four channels). Read your motherboard manual as if you want to use dual-channel memory, you will have to plug your RAM sticks on the right channel to make them work properly. For example, if you have two RAM sticks, you will likely have to plug them into the A1 and B1 slots to use the dual-channel memory feature.

Important notes

  • The following frequencies of memory stick are compatible with dual-channel technology: DDR1600, 2100, 2700, 3200, and those with a higher frequency.
    1. When using a single RAM stick, location A1 must be configured in single-channel mode.
    2. When using 2 RAM sticks of different brands, paired slots must be configured in single-channel mode.
  • To enable dual-channel mode, it is necessary to use 2 (identical) RAM sticks in the paired slots.
  • If you want to use 3 RAM sticks of different brands, it is necessary to use two identical bars in the first group and the last one of any other brand but with the same frequency.
  • On motherboards having both 2 DDR2 ports and 2 DDR ports, only DDR2 ports can be used.
  • This manipulation can be considered an inexpensive update, increasing the life span of your PC.
