This article describes what is meant by DDR4 SO-DIMM.

DDR4 SO-DIMM (Double Data Rate 4 Small Outline Dual Inline Memory Module) is a type of RAM used in laptop computers, small form factor desktops, and embedded systems. The SO-DIMM form factor is smaller than a standard DIMM (Dual Inline Memory Module), allowing it to fit in smaller computer systems with limited space for memory modules. This is currently the standard RAM used in Elo AIO touch computers.

DDR4 SO-DIMM operates using the DDR4 technology, which provides higher speed and improved power efficiency compared to previous DDR generations. DDR4 SO-DIMM typically has clock speeds ranging from 2133 MHz to 2400 MHz and higher, providing improved performance compared to DDR3 SO-DIMM.

Below is an example of the DDR4 SO-DIMM used in an EloPOS System
