Dell 32GB 2666MHz Pc4-21300 Ecc Registered DDR4. DDR3 SDRAM (Double Data Rate 3 Synchronous Dynamic Random Access Memory) and DDR4 SDRAM (Double Data Rate 4 Synchronous Dynamic Random Access Memory) are types of memory used in computers. DDR3 and DDR4 have some similarities, such as being double data rate and synchronous, but they also have some key differences. DDR3 has a lower clock speed, typically ranging from 800 MHz to 1600 MHz, while DDR4 has a higher clock speed, typically ranging from 1600 MHz to 3200 MHz. This means that DDR4 can transfer data faster than DDR3.
