Power Up Your Laptop With SO-DIMM 4 GB DDR2-SDRAM Modules

You're looking to add some more RAM to your laptop, but when you do some research about your model, you discover there's not too much space inside to do this. Short for Small Outline Dual Inline Memory Module, a 4 GB SO-DIMM is a smaller alternative to a dual in-line memory module and is a suitable choice for systems with limited space, such as notebooks and laptops.

What Is a SO-DIMM Memory Module?

Ranging from DDR2 to DDR2, SO-DIMMs are usually employed on laptops and notebooks based on Mini-ITX motherboards. However, they are also a suitable choice for networking hardware such as routers and high-end office printers that allow for memory upgrades. These memory modules are generally about half the length of a DIMM and allow you to incorporate them into slim laptops to upgrade their RAM. You can opt for buffered or unbuffered modules, but keep in mind that unbuffered ones are faster, whereas buffered modules put less strain on the memory controller, but they are slower, and as such better suited for servers.

How Many Pins Does a SO-DIMM DDR2-SDRAM Module Have?

You can easily identify the type of SODIMM by the number of notches they have. The number of pins differs between various types as well, with DDR2 types ranging from 100 to 200-pin modules. Keep in mind that DDR2 modules are not interchangeable with DDR3 and DDR4 modules, so make sure you know which type your computer uses before making a purchase.

Is DDR2-SDRAM Compatible With All Laptops?

While you can generally use these modules with any type of laptop as long as you match the specs on the RAM, you should make sure that the motherboard/bios of the machine supports extra RAM. For example, there are motherboards that are capped at 2 GB of RAM maximum. In other situations, the laptop may not accept a single 4 GB of RAM, and you may end up using two sticks instead. You should also check whether your laptop uses ECC or non-ECC memory and buy memory sticks accordingly. 

How Important Is the MHz on RAM?

The choice of MHz on your RAM should depend on what you intend to do with your computer. The number of MHz for RAM refers to the maximum number of clock cycles per second, and a higher memory frequency means a faster system because of the higher data bandwidth. Large amounts of RAM are essential for laptops and PCs used for graphics applications or gaming.
