Is DDR4 and DDR3 same size?
Both DDR3 and DDR4 DIMMs are 5¼ inch (133.35 mm) in length but the pins in DDR4 are spaced closer (0.85mm) than DDR3 (1mm). They are also different in height and thickness — the increased height of DDR4 modules (31.25mm instead of DDR3’s 30.35mm) makes signal routing easier, and the increased thickness (1.2mm vs.
