Dell PowerEdge XR5610 memory kit

This 128GB kit contains eight 16GB DDR5 RDIMMs built for the Dell PowerEdge XR5610 rack server. Registered ECC modules detect and correct single-bit errors to protect data integrity in always-on workloads. The kit targets IT teams who need validated capacity expansion for this specific platform.

288-pin registered DDR5 build

Each module uses a 288-pin DDR5 interface with a 1Rx8 organisation and operates at 1.10V. The registered design adds a buffer that reduces electrical load on the server memory controller, helping stability when all eight slots are populated. No heat spreader is fitted, so airflow across the bare PCB must be provided by the chassis.

Eight matched modules in one package

The box delivers the full 128GB as a matched set of eight 16GB sticks, removing the need to source individual DIMMs. CL40 latency and 4800MT/s speed are pre-configured for the qualified server profile. Buyers who need a different capacity per module or a non-ECC configuration cannot use this kit.
