NEMIX RAM 128GB (2x64GB) DDR4 3200 CL22 2Rx4 ECC RDIMM memory upgrade

Dell PowerEdge XR server memory kit

This 128GB kit contains two 64GB DDR4 3200 registered ECC RDIMMs built for Dell PowerEdge XR4000w, XR4510c and XR4520c rack servers. Each module runs at 1.20V with CL22 latency and a 2Rx4 organisation. The registered design adds a buffer that reduces electrical load on the server memory controller.

Sustained load behaviour with registered ECC

Error-correcting code detects and corrects single-bit errors during continuous operation, while the registered buffer stabilises signalling across all ranks under heavy multi-threaded workloads. Modules are stress tested under load before shipping to verify stability in mission-critical environments. The 1.20V operating voltage helps maintain consistent thermals during extended duty cycles.

Installation notes for 288-pin RDIMM slots

The 288-pin DDR4 RDIMM form factor fits directly into compatible Dell server DIMM slots without adapters. Installation typically takes minutes by following the server owner’s manual for population order and configuration rules. No heat spreader is present, so airflow across the modules must be maintained by the server chassis design. Buyers needing non-ECC or unbuffered memory for workstation boards cannot use this kit.
