Capacity & Use Case

This 256 GB kit contains two 128 GB DDR5 RDIMMs built for Dell PowerEdge R760 rack servers. Registered ECC operation and a 4Rx4 organisation suit workloads that demand data integrity and large memory footprints such as virtualization, databases or high-performance computing.

Compatibility Check

Verify that your motherboard accepts 288-pin DDR5 registered DIMMs running at 4800 MT/s with CL40 timing at 1.1 V. Confirm the platform supports 4Rx4 modules and that the BIOS is current enough to initialise the full 256 GB capacity. Check the server manual for approved population rules and maximum supported rank per channel.

Build & Daily Implications

Modules ship without heat spreaders, relying on server chassis airflow for cooling; ensure your rack enclosure provides adequate front-to-back flow. Registered buffering adds a clock cycle of latency but reduces electrical load on the memory controller, helping stability in fully populated configurations. The 288-pin connector is keyed for DDR5 only, preventing accidental insertion into older slots.

Questions sur cet article

Does the kit include any mounting hardware or cooling accessories, or must they be purchased separately?

The kit supplies two 128 GB DDR5 RDIMM modules only; no heat spreaders, brackets or cables are included, and registered DIMMs do not require additional mounting hardware.

When would I choose the 256 GB 4Rx4 kit over a lower-capacity alternative?

Choose this 256 GB kit when the workload demands maximum registered ECC capacity per channel and the platform supports 4Rx4 modules at DDR5 4800 CL40.

What does the DDR5 4800 CL40 rating deliver in a Dell PowerEdge R760?

In a Dell PowerEdge R760 the modules run at 4800 MT/s with CL40 latency at 1.1 V, providing registered ECC throughput matched to the server's memory controller.
