Dell PowerEdge XR7620 memory upgrade

This 32GB DDR5 4800 ECC RDIMM is built for the Dell PowerEdge XR7620 rack server. It delivers registered, error-correcting memory for workloads that demand data integrity. The single 32GB module uses a 2Rx8 organisation at 1.10V and fits the 288-pin DDR5 slot.

Sustained-load behaviour

Registered buffering and ECC keep data consistent during long compute runs on the XR7620. The CL40 latency and 4800 MT/s rate provide steady throughput for virtualisation, databases and edge tasks. Modules are stress-tested under load before shipping to reduce early-life failures.

Build and connectors

The bare-module design omits a heat spreader, relying on the server's directed airflow for cooling. The 288-pin RDIMM keying prevents mis-insertion in the XR7620 memory slots. Major OEM DRAM from Samsung, Micron or Hynix underpins the lifetime replacement guarantee.

Questions about this item

How much power does the 1.1V DDR5 RDIMM draw under sustained load in the XR7620?

The module operates at 1.10V, the standard DDR5 voltage, and is a registered ECC RDIMM so the server chipset handles buffering; exact wattage depends on the XR7620 memory controller and workload.

What server configuration is required for this 288-pin 2Rx8 module to be recognised?

The XR7620 must support DDR5 4800 registered ECC RDIMMs and have a free 288-pin slot; the module is qualified for that platform and installs like any standard server DIMM.

Will this CL40 4800MHz stick run at rated speed alongside slower DDR5 modules already in the XR7620?

The server memory controller will negotiate a common speed; all installed DDR5 RDIMMs will operate at the lowest rated frequency and loosest latency among them.
