DefinitionDDR4 SDRAM is the successor to DDR3 SDRAM and the fourth-generation DRAM standard of the DDR SDRAM series.
ExplanationIt transfers data faster than DDR3 and lowers the supply voltage to cut power consumption. Its module has a different pin count and a different notch position from DDR3, so it cannot be inserted into a DDR3 slot.
