Overview
Released in 2014, DDR4 was the standard system memory for nearly a decade. It offered significant improvements over DDR3 in terms of speed, power efficiency, and capacity.
Key Improvements
- Higher Speeds: Data rates ranging from 1600 MT/s to 3200 MT/s and beyond.
- Lower Voltage: Operates at 1.2V compared to DDR3's 1.5V, reducing power consumption.
- Increased Density: Allows for larger memory modules (up to 64GB or more per stick).
Legacy
While being replaced by DDR5, DDR4 remains widely used in many existing systems and budget-oriented builds.
