Dell PowerEdge R760xa memory kit

This NEMIX RAM kit supplies 512GB across eight 64GB modules built for the Dell PowerEdge R760xa server. It targets administrators who need maximum registered ECC capacity in a single validated package. The modules arrive new and ready for immediate installation.

Registered DDR5 4800 ECC RDIMM

Each module runs at DDR5 4800 (PC5 38400) with CL40 latency, 2Rx4 organisation and 1.10V operation. The 288-pin registered design with on-die ECC is the single specification that determines whether the memory will post and run stably in the R760xa.

Eight 64GB modules fill 512GB

The kit populates eight slots with 64GB RDIMMs, delivering the full 512GB capacity for dense virtualisation, in-memory databases or large-scale compute jobs. Workloads that exceed this ceiling or require faster speeds will need a different memory configuration.

Questions about this item

What does the 4800 MT/s rating mean when the modules are installed in a Dell PowerEdge R760xa?

The server will run the memory at 4800 MT/s, delivering PC5-38400 bandwidth per module as long as the processor and BIOS support that speed.

How does the DDR5 RDIMM interface and CL40 latency affect real-world throughput?

Registered DDR5 at CL40 provides error-corrected data transfer at 4800 MT/s; the registered buffer adds one cycle but allows the full 8-module population the R760xa supports.

Will the 288-pin 2Rx4 modules fit the R760xa memory slots without clearance issues?

Yes — each 64 GB stick is a standard 288-pin DDR5 RDIMM with no heat spreader, so it seats directly in the server's DIMM sockets.
