    Description

    Samsung DDR4 Registered DIMMs

    Samsung DDR4 Registered DIMMs (or RDIMMs) are designed with an additional hardware register between the DRAM module and the system's memory controller. This register helps to reduce the electrical load on the memory controller and ensures sustained stability, even with an increase in the number of installed memory modules. As a result, RDIMMs are the preferred choice for deployment in server-class computing systems.

    Optimized for High-Performance Computing

    In addition to the features of Registered DIMMs, Samsung DDR4 memory is also available as Registered DIMM, providing an optimized solution for highly virtualized environments, high-performance computing, and networking. The semiconductor modules of Samsung DDR4 are designed with a new system circuit architecture that delivers higher performance with lower power requirements compared to previous memory products. This results in doubled bandwidth, reduced voltage, and significantly lower power consumption, improving overall performance and optimizing the total cost of ownership.

    Enhanced Reliability and Serviceability

    Samsung DDR4 also offers enhanced reliability, availability, and serviceability (RAS) features, providing improved signal integrity and overall reliability. These features make Samsung DDR4 an ideal choice for critical computing systems where stability and performance are crucial.
