For laptops, the most common type of RAM used is Small Outline Dual Inline Memory Module (SODIMM) due to its smaller size compared to DIMMs used in desktops. DDR5 is the latest generation of RAM, offering higher speed and efficiency. ECC (Error-Correcting Code) DIMM DDR5 and Registered DIMM DDR5 are typically used in servers and high-end workstations for error correction and stability, not in standard laptops.
High latency DDR5 is not a desirable specification for RAM as lower latency is preferred for faster performance.
