The answer is no, for the most part. The first difference between the two is the size of the memory modules. Most desktop memory modules measure between 4.5 and 5.0 inches. Laptops use a modified form of DIMM called SO-DIMM, or small outline dual inline memory modules.

Subsequently, question is, what type of RAM is used in laptops? There are two types of RAM used in laptops produced in the last two years and only one offers an upgrade path: DDR4. DDR4 modules, or SO-DIMMS, are sold in varying speeds and sizes. The most common laptop memory speeds today are DDR4/2133 and DDR4/2400.

In this regard, are all laptop ram the same?
