Dell PowerEdge XR5610 memory kit

This 256GB kit contains four 64GB DDR5 modules built for the Dell PowerEdge XR5610 rack server. Each module is a registered ECC RDIMM that adds error correction and signal buffering for stable operation in multi-socket enterprise workloads.

DDR5 4800 registered ECC constraints

The kit runs at DDR5 4800 with CL40 latency and 1.1V voltage. Registered DIMMs require a motherboard that supports registered memory and ECC; they will not function in consumer platforms or unbuffered slots. Mixing registered and unbuffered modules is not supported by the server memory controller.

256GB capacity across four slots

The 4x64GB configuration fills four DIMM slots to reach 256GB total capacity. Buyers who need a different total capacity or a different module density must select another kit; this part number does not offer alternative capacities or single-module options.

Questions about this item

Should I choose the 256 GB kit or a smaller capacity for my Dell PowerEdge XR5610?

The kit supplies 256 GB total across four 64 GB modules, filling four slots and matching the server's supported DDR5 4800 registered ECC configuration.

What does the DDR5 4800 speed rating deliver inside a PowerEdge XR5610?

At 4800 MT/s the modules run at the platform's native DDR5 4800 data rate, providing PC5-38400 bandwidth with CL40 latency for stable registered ECC operation.

How does the 288-pin RDIMM interface limit performance in this server?

The 288-pin DDR5 RDIMM form factor locks the kit to the XR5610's registered memory channels, capping speed at the platform's 4800 MT/s maximum and requiring ECC registered topology.
