Dell PowerEdge R760xa DDR5 RDIMM

This 16GB DDR5 4800 ECC registered DIMM is built for the Dell PowerEdge R760xa rack server. IT teams choose it when they need verified compatibility and error-correcting stability in a single-slot module. The registered design reduces electrical load on the memory controller for reliable operation in dense configurations.

Upgrade from slower DDR5 or smaller capacity DIMMs

Replacing lower-speed DDR5 modules with this PC5-38400 part raises bandwidth to 4800 MT/s while keeping latency at CL40 and voltage at 1.10V. The jump is worthwhile when workloads demand higher throughput per channel and the platform supports DDR5 4800 registered memory. Mixing speeds will force the system to run at the slowest installed rate.

16GB single-rank capacity headroom

The 1Rx8 organisation delivers 16GB in one rank, leaving additional slots open for future expansion on the R760xa. It handles virtualisation hosts, database buffers and compute nodes that fit within this per-module footprint. Workloads requiring more than 16GB per slot or higher frequencies than 4800 MT/s will need different modules.

Questions about this item

Does the 288-pin DDR5 RDIMM fit the Dell PowerEdge R760xa memory slots?

Yes, the 288-pin DDR5 RDIMM form factor matches the R760xa DIMM slots exactly.

What is the correct orientation step when installing this registered ECC module?

Align the off-centre notch on the module with the key in the slot, press straight down until both side clips click, and verify the registered buffer seats fully.

When should the 16 GB 1Rx8 CL40 module be replaced?

Replace it if memory diagnostics report uncorrectable ECC errors, the system logs repeated corrected errors, or a capacity upgrade is required.
