Dell PowerEdge R7615 Server Memory Kit

This 64GB kit contains four 16GB DDR5 4800 ECC Registered RDIMM modules built for the Dell PowerEdge R7615 rack server. It targets IT professionals who need validated, error-correcting memory to keep mission-critical workloads stable and supported.

Simple DIMM Installation and Validation

Modules slot into the 288-pin RDIMM sockets and are recognised automatically by the server BIOS. Each stick has been stress-tested under load, so the usual causes of boot failure — mismatched ranks or unqualified chips — are eliminated before the kit ships.

64GB Registered ECC Capacity at 4800 MT/s

The four-module kit delivers 64GB of registered ECC memory running at PC5-38400 with CL40 latency at 1.10V. It comfortably handles virtualisation, database and heavy multi-threaded tasks; larger datasets that exceed 64GB will require additional qualified DIMM slots.

Questions about this item

How can I confirm the 4800 MT/s speed and CL40 latency are active after installing the four 16 GB modules in my PowerEdge R7615?

Enter the system BIOS or use a tool such as CPU-Z to verify the memory runs at DDR5 4800 with CL40 timings and that all 64 GB are recognised.

What ships in the kit and do I need any extra parts for installation?

The kit contains four 16 GB DDR5 4800 ECC RDIMM modules (1Rx8, 1.10 V, 288-pin); no additional components are required for a standard server DIMM slot install.

Which capacity or speed variant should I pick for a Dell PowerEdge R7615?

Choose the 64 GB (4 x 16 GB) DDR5 4800 ECC RDIMM kit (part MR38400-618K4) — it matches the R7615's supported speed, voltage and registered ECC requirement.
