What is the difference between dual-channel and single-channel memory?
1. Different requirements

Memory channel single channel means that one memory module is needed, and dual channel needs at least 2 memory.

2, memory capacity is different

In the case of a single 2G, two channels are two memory modules, and a single channel is one memory module.

3.Read speed is different

Single-channel memory can only be read or written at the same time; dual-channel refers to the use of different channels for memory read and write, which can be read and written simultaneously, and the memory bandwidth is doubled.

4. Different processing capabilities

Dual-channel has advantages over single-channel in reading and writing. Opening software or files in daily life is definitely faster than single-channel. For example, when running some large games, due to memory bandwidth issues, the performance improvement brought by dual channels can be clearly felt.
