Dell PowerEdge R760xa Compatible Kit

This 32GB kit contains two 16GB DDR5 RDIMM modules built for the Dell PowerEdge R760xa rack server. Registered ECC operation protects data integrity in mission-critical workloads. The 4800MHz speed and CL40 latency deliver stable throughput for virtualisation and database tasks. IT teams can deploy the matched pair with confidence in enterprise environments.

Verify RDIMM Slots and CPU Support

Confirm the server has free 288-pin RDIMM slots and that the installed processors support DDR5 4800 registered memory. The 1Rx8 organisation must match the platform's population rules for optimal channel performance. Check the system firmware is current before installation to avoid POST issues. Mixing with different ranks or speeds may disable ECC or reduce bandwidth.

Registered Design With Major OEM Chips

Modules use Samsung, Micron or Hynix components selected for server-grade reliability. The registered buffer reduces electrical load on the memory controller, allowing higher capacities per channel. No heat spreader is fitted, so airflow across the DIMMs must be maintained by the chassis fans. Lifetime replacement coverage backs the validated compatibility promise.

Questions about this item

Does the kit include both 16GB modules or do I need to buy a second stick?

The kit contains two 16GB modules for a total of 32GB, so no additional sticks are required.

Should I pick the 4800 CL40 kit or a different speed grade for my Dell PowerEdge R760xa?

The 4800 CL40 specification matches the Dell PowerEdge R760xa memory controller, making it the correct choice for that server.

What does the 4800 CL40 rating deliver when installed in a registered DDR5 server board?

The modules run at 4800 MT/s with CL40 latency at 1.10V, providing ECC error correction and registered buffering for stable server operation.
