PC RAM Compatibility

Knowing the type of RAM your computer uses is crucial to upgrading.

While RAM and computer memory may seem confusing, understanding the basic difference between memory modules will help you figure out the type you need for an upgrade. Upgrading your RAM will often increase PC performance and speed.

Compatibility

Different computers are designed with specific parts that are supposed to be used with certain types of memory. Different memory modules are designed to meet different specifications based on bandwidth, speed and efficiency.

Desktop vs. Laptop Memory

While desktops use dual in-line memory modules (DIMMs), laptops use small outline dual in-line memory modules (SO-DIMMs). Due to the smaller size of the computers they go in, SO-DIMMs are physically smaller, though technologically similar to desktop DIMMs.

Warning

If you purchase the wrong type of RAM for your PC, chances are it may not even physically fit. If your RAM doesn't fit, don't force it, that could ruin the memory slot. If you do happen to install improper memory, your computer won't work properly.

Prevention/Solution

When considering a memory upgrade, you can often find the type you need in the owner's manual that came with your computer. Alternately, many websites have tools to help determine the type of RAM your PC needs.
