Using dual channel memory equips you with two RAM pipelines to the CPU, to eliminate a bottleneck due to system bus. Most dual channel boards have one stick of RAM set to single mode. This article will explain all about Dual Channel RAM.
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 capacity of the system. Note: It is recommended that, when using Dual Channel, you use identical memory sticks in pairs (frequency, capacity, of the same brand if possible).
Memory locations are noted as indicated below:
Dual Channel: [A1-A2] and/or [B1-B2]
To make use of dual channels, you have to get a similar pair of RAM intended for use in your system. If you have 2 sticks of different capacity and memory size, ascertain that they have the same hardware configuration and build. Deploy the RAM in similar colored points, for example, when one RAM is inserted in the blue slot, the other must also be in a blue slot. This will make the dual channel activate. If the colors mismatch, the dual channel mode will not work. Make sure to have the same style chip in both slots of the same color.
