Dell PowerEdge XR7620 256GB kit

This 256GB kit contains four 64GB DDR5 registered DIMMs built for the Dell PowerEdge XR7620 rack server. Each module runs at 4800MT/s with CL40 latency at 1.1V. ECC and registered buffering protect data integrity in mission-critical workloads.

Suited for XR7620 capacity expansion

IT teams scaling memory in a PowerEdge XR7620 will match the platform's validated configuration. Buyers needing unbuffered UDIMMs, lower capacities, or consumer desktop memory should look elsewhere because this kit is registered ECC RDIMM only.

Four-module kit simplifies population

The package delivers four identical 64GB sticks so all channels can be filled in a single step. No heat spreaders are included, relying on server airflow. No extra software or cables ship with the memory.

Questions about this item

Does the Dell PowerEdge XR7620 require a specific BIOS version or CPU generation to run this 256 GB DDR5 4800 kit?

The module specifications list DDR5 4800, CL40, 1.1 V, 2Rx4 registered ECC, 288-pin RDIMM — these are the electrical and mechanical requirements the server must meet.

Can I install this four-module 256 GB kit alongside existing DDR5 RDIMMs of a different capacity or rank in the same server?

The kit provides four 64 GB 2Rx4 modules; mixing different capacities or ranks is governed by the Dell PowerEdge XR7620 memory population rules in the system manual.

After seating all four modules, what indicator confirms the server recognises the full 256 GB at 4800 MT/s with ECC active?

POST memory test and the BIOS memory configuration screen will show 256 GB total, DDR5 4800 speed, and ECC enabled for each installed RDIMM.
