DDR4 R-DIMM Designed to meet the increased adoption of cloud computing, virtualization and high-performance computing technologies, Transcend's DDR4 R-DIMMs are fully compatible with Intel® Xeon® E5-2600 v3 server family processor (codenamed as "Haswell-EP"). Each R-DIMM module is constructed with top quality DRAM chips and rated at 2133MHz/2400MHz, maxmizing data transmission efficiency with higher bandwidth of up to 17GB/19GB/s. Operated at a nominal voltage of just 1.2V, Transcend's DDR4 R-DIMMs reduce electrical load on the memory controller, offering power savings of up to 40% compared to 1.5V standard DDR3.
