128GB DDR5 ECC RDIMM kit for Dell PowerEdge R760xa

This registered DDR5 memory kit delivers 128GB across four 32GB modules built for the Dell PowerEdge R760xa rack server. Error-correcting code and registered buffering protect data integrity in mission-critical workloads. The kit targets IT professionals who need validated, system-specific memory for enterprise environments.

Tool-less DIMM installation

Modules slot into the 288-pin DDR5 sockets without tools, and the manufacturer notes that upgrades typically take minutes. The common issue is ignoring the server's population rules — mixing ranks or filling slots in the wrong order prevents the system from posting. Always follow the Dell service manual for the correct sequence.

4800 MT/s DDR5 speed with CL40 latency at 1.1V

The kit operates at DDR5 4800 (PC5-38400) with CAS latency 40 and a 1.1V supply, matching the platform's native memory specification. If the server requires a different data rate, voltage or latency profile, this kit will not meet the requirement.

Questions about this item

How do I confirm the 128GB kit is running at DDR5 4800 CL40 after installation?

Open the BIOS or iDRAC and check that each slot shows 32GB at 4800 MT/s with CL40 timings and 1.10V; run a memory stress test to verify stability.

What ships in the box and what must I source separately?

The kit includes four 32GB 288-pin DDR5 RDIMM modules; no cables, brackets or additional hardware are supplied.

Should I choose the 128GB 4x32GB kit or a different capacity for the PowerEdge R760xa?

Select this 128GB kit when the server requires four 32GB registered ECC modules at DDR5 4800; other capacities use different module counts or densities.
