What is the difference between single and double sided memory modules?

The choice stating that single sided memory modules contain RAM on only one side is correct because single sided modules have memory chips installed on one side of the printed circuit board (PCB) only. This design allows for a more compact module but limits the total amount of memory that can be installed on a single module.

Single sided memory modules can be beneficial in situations where space is tight or when dealing with motherboards that may have restrictions on the height of memory due to other components nearby. This also means that they may be a bit less expensive to produce compared to double sided modules, which require chips on both sides.

In contrast, double sided modules have RAM chips on both sides of the PCB, allowing them to store more memory per module. This design can maximize the memory capacity within the physical constraints of the motherboard’s memory slots. However, the presence of chips on both sides does not necessarily imply better performance; the speed and performance would depend more on other factors such as RAM type, specifications, and system compatibility.

Understanding this distinction is vital for selecting the appropriate memory module for a given system, depending on the available space and memory requirements.
