A computer system’s memory slots are important for storage, and for the electrical signals that help control the computer’s operations.
Computer memory slots come in two varieties: DIMM (Dual Inline Memory Module) and SODIMM (Single Outline DIMM). A DIMM slot is typically found on the motherboard, while a SODIMM slot is typically found on laptop or desktop PCs.
DIMMs and SODIMMs have different capacities and shapes. A DIMM can hold up to 64GB of data, while a SODIMM can hold up to 128GB.
That’s because they have different dimensions – a DIMM is shorter and wider than a SODIMM.
The reason there are four DIMM slots is that a 4GB DIMM is the smallest size that can be used in a modern PC. The three larger sizes are 8GB, 16GB, and 32GB.
So if you want to install more than 4GB of memory in your PC, you need to use a combination of DIMMs and SODIMMs.
