Samsung DDR4 DIMMs are designed with an additional hardware register between the DRAM module & the system's memory controller. RDIMMs present several advantages for the system, such as a lower electrical load on the memory controller & sustained stability even with an increase in the number of installed memory modules. Thus, RDIMMs are often the default choice for deployment in server-class computing systems. In addition to DIMM's features, Samsung DDR4 memory provides an optimized solution for highly virtualized environments, high-performance computing & networking. Semiconductor modules of Samsung DDR4 are designed with system circuit architecture to deliver higher performance with low power requirements than previously available memory products. Doubled bandwidth, along with reduced voltage & dramatically lower power consumption, improves performance & optimizes the total cost of ownership. Samsung DDR4's enhanced reliability, availability & serviceability (RAS) features provide enhanced reliability & enhanced signal integrity (S/I).
