NEMIX RAM
16 GB DDR5-4800 ECC registered DIMM with CL40 latency, 1.1 V operation and single-rank 1Rx8 layout built for Dell PowerEdge XR5610 servers
This 16 GB DDR5 module is built for the Dell PowerEdge XR5610 rack server. It delivers registered ECC memory for workloads that require error correction and signal integrity. The single-rank 1Rx8 organisation keeps electrical loading low on the memory bus. It is not suited for desktop boards or consumer laptops that lack RDIMM support.
The module runs at 4800 MT/s with a CAS latency of CL40 and operates at 1.1 V. Registered buffering adds one clock cycle of latency but allows larger memory populations per channel. ECC corrects single-bit errors and detects multi-bit errors, essential for data integrity in server environments. Systems that do not support registered DDR5 or ECC will not recognise this DIMM.
Major OEM chips from Samsung, Micron or Hynix are assembled without a heat spreader, relying on server chassis airflow for cooling. The 288-pin RDIMM keying prevents insertion into UDIMM or SO-DIMM slots. Installation follows the Dell PowerEdge XR5610 service manual; no additional tools are required beyond those used for standard server memory maintenance.

The 16GB 1Rx8 module fits a single 288-pin slot at 1.1V and is validated for the XR5610; add identical modules to scale capacity in matched channels.
The module runs at 4800 MT/s with CL40 latency, providing PC5-38400 bandwidth for registered ECC workloads on the server platform.
The registered 288-pin DDR5 interface caps operation at the rated 4800 MT/s and CL40 timing, with ECC and 1.1V voltage enforced by the server memory controller.
