Is my RAM compatible with my motherboard?
A memory upgrade is one of the easiest and most affordable ways to improve the performance of your system. While incredibly easy to upgrade and install, it’s paramount to check compatibility when purchasing a memory upgrade. For memory to work on your system, it must be compatible with your motherboard. We’ll show you how to get RAM that your motherboard will support. Find out other ways to fix a slow computer here.
The type of memory you purchase must match what your system’s motherboard will support. Depending on the age of your computer, it was designed to use one of the following types of memory technology:
- SDR (single data rate) technology primarily appeared in systems manufactured before 2002.
- DDR (double data rate) technology began to appear in systems manufactured in 2002.
- DDR2 (second generation double data rate) technology began to appear in 2004.
- DDR3 technology began to appear in 2007.
- DDR4 technology began to appear in 2014.
What is a motherboard?
The motherboard is the circuit board on which the processor, memory modules, storage (SSD or hard drive), and other components are located.
As a rule, each generation of memory technology has faster frequencies, runs on lower voltage, and boasts lower latencies than the generation of technology it succeeds. However, if your system was designed for DDR2 technology, it won’t be able to support DDR3 modules. Find out more about the generations of DDR technology here. Because each type of memory has different notch locations (which are important for installation), and motherboards have ridges that accommodate only one notch location, motherboards are generally able to support only one type of memory technology.
