128 GB DDR5 RDIMM for Dell PowerEdge R7615

This 128 GB DDR5 registered DIMM is built for Dell PowerEdge R7615 rack servers that require ECC memory. It targets IT teams expanding capacity in mission-critical workloads where data integrity and stability are mandatory.

DDR5 4800 PC5-38400 registered operation

The module runs at 4800 MT/s with CL40 latency at 1.10 V. Registered buffering and 4Rx4 organisation place electrical load on the memory controller, so total capacity per channel is limited by the server platform's qualified vendor list.

No heat spreader, 288-pin form factor

The bare green PCB fits standard 288-pin DDR5 slots without extra height. Absence of a spreader means airflow from the server chassis must handle cooling directly. Compatibility is validated for the R7615 platform using major OEM DRAM from Samsung, Micron or Hynix.

Questions about this item

Should I pick the single 128GB module or combine smaller sticks to reach the same capacity?

This listing is a single 128GB stick (1x128GB). Add more identical modules to scale capacity further if your R7615 has free slots.

What does the DDR5 4800 speed mean for actual workloads on the R7615?

The module runs at DDR5 4800 with CL40 latency, giving the rated data rate the platform's memory controller expects for stable operation.

How does the 288-pin DDR5 RDIMM interface limit what I can install?

It fits only DDR5 RDIMM slots; the registered design and ECC function require a server chipset that supports registered ECC memory.
