When you decide on the type of RAM to use, you must decide on more technical details; for example, the configuration of channels, which will be
dictated for the most part by the motherboard. Your particular environment might need RAM that doesn’t lag, so memory latency should be another consideration. There are several other lesser considerations, such as whether to use single-sided or double-sided RAM, parity, ECC RAM, and whether to use buffered RAM. For the most part, these additional factors don’t play into the decision much. Your motherboard dictates whether the RAM is single-sided or double-sided, and parity and ECC RAM are more rare nowadays. So let’s concentrate on the different channel architectures for RAM.
