This is a Kingston Fury Renegade Pro 128GB memory kit (KF556R36RBK4-128) made up of four 32GB DDR5-5600MT/s ECC Registered modules, designed for high-end workstation and server motherboards that support registered ECC memory rather than standard desktop DIMMs. Each module runs 1Rx4 ranking at CL36 timings and 1.25V, uses a black aluminium heatsink for thermal control under sustained load, and supports Intel XMP 3.0 for one-click overclocking/timing profiles on compatible boards. A built-in power-management IC handles on-module voltage regulation. Aimed at workstation builders and system integrators assembling high-core-count professional workstations or small servers that need both large total capacity and ECC data-integrity protection, backed by Kingston's limited lifetime warranty in a retail-packaged kit.
