Why DDR3 RAM is Not Compatible with DDR4 Explained

Discover the reasons behind the incompatibility of DDR3 and DDR4 RAM, ensuring optimal hardware performance and stability.

396 views

DDR3 is not compatible with DDR4 due to differences in their physical and electrical characteristics. DDR3 modules have 240 pins whereas DDR4 has 288 pins, making them physically incompatible. Additionally, they operate at different voltages and use different signaling methods. These differences ensure that DDR3 RAM cannot be used in DDR4 slots and vice versa, safeguarding against potential hardware damage and ensuring system stability.
