Episode 44: RAM Types — DDR Three, DDR Four, DDR Five, SODIMM, ECC

This episode focuses on the various types of system memory covered in the A Plus exam. We start by distinguishing between DDR 3, DDR 4, and DDR 5, outlining differences in voltage, speed, and pin count. You’ll also hear how to identify these modules visually and understand which platforms or chipsets support each type. We emphasize backward compatibility and the risks of inserting the wrong module into a motherboard.Next, we explain the importance of SODIMM modules, typically used in laptops and small form factor systems, and ECC memory, which is essential for error correction in servers and mission-critical environments. These distinctions are often tested in hardware specification questions, and by mastering them, you’ll feel more confident identifying the right type of RAM for any given system.
