The Dell AD170482 is a high‑capacity server‑grade memory module designed for enterprise systems. With 128 GB per module, DDR5 architecture running at 6400 MT/s (PC5‑51200), it offers very high bandwidth suitable for workloads like virtualization, large in‑memory databases, analytics, high‑performance compute or data‑centres.Being an ECC Registered (RDIMM) module means it includes error‑correcting code support and a register (buffer) on the module to interface between the DRAM chips and the memory controller, which improves signal integrity and scalability (more modules per channel, more DIMMs per system) compared to unbuffered memory. The dual‑rank (2R) nature means there are two “ranks” (groups of DRAM chips) on the module; “×4” likely refers to the internal chip organisation (meaning each chip is 4 bits wide, etc). This gives a balance between capacity, performance and compatibility in server environments.Voltage being 1.10 V is lower than many older DDR4 modules (which typically ran 1.2‑1.35 V), so this DDR5 module is more power‑efficient for its performance class. The 288‑pin form factor confirms it's for server/workstation desktops (not laptop SO‑DIMM). Compatibility would require a server or workstation motherboard that supports DDR5 RDIMM at 6400 MT/s and 128 GB modules—and it is referenced for use in many of Dell’s own PowerEdge servers (or compatible OEM systems)
