Samsung DDR4 Unbuffered DIMMs (or UDIMMs) are the most common type of memory used on desktop systems. A UDIMM memory module does not contain any buffer or additional hardware register between the memory module and the system's memory controller. UDIMMs also consume much lower power, and have much lower data access latencies than buffered or registered memory. As the semiconductor memory is widely used in current generation computers, DDR4 is considered the industry standard commercial version of DRAM memory. Advancements in semiconductor design, development, and fabrication processes have enabled the development of high-performance DRAM memory. By leveraging the full potential of Samsung DDR4, you can increase computing performance, while consuming less energy.
