System-specific DDR5 ECC RDIMM for Dell PowerEdge

This 128 GB registered DDR5 module runs at 4800 MT/s with CL40 latency and 1.10 V operation. It uses a 4Rx4 organisation and 288-pin form factor designed for the Dell PowerEdge XR7620 rack server. ECC and registered buffering support data integrity in enterprise workloads.

Thermals noise and power draw in normal use

The module operates at the standard DDR5 voltage of 1.10 V without a heat spreader. Power consumption scales with the 4800 MT/s data rate and 4Rx4 density during typical server operation. Acoustic output is determined by the server chassis fans rather than the memory itself.

Behaviour under sustained load

Major OEM Samsung Micron Hynix chips are stress tested under load to maintain stability during continuous operation. Registered buffering reduces electrical load on the memory controller during extended sessions. ECC corrects single-bit errors that can accumulate over long-running compute tasks.

Compatibility limited to qualified Dell platforms

This part is validated for the Dell PowerEdge XR7620 and is not intended for consumer desktop boards or non-Dell server platforms. Buyers needing unbuffered UDIMM memory or higher-speed DDR5 bins should select a different module.

Questions about this item

How do I install this 288-Pin DDR5 RDIMM in the PowerEdge XR7620 and what step is often missed?

Align the notch on the 288-pin module with the slot key, press firmly until both side clips click, then verify the server BIOS recognises the full 128GB capacity.

What maintenance or replacement will this ECC RDIMM need during its service life?

No scheduled maintenance is required; if a correctable error count rises or the module fails, replace it with another DDR5 4800 4Rx4 1.1V RDIMM of matching capacity.

What limit appears first when this 128GB 4Rx4 module runs sustained workloads?

The quad-rank 4Rx4 organisation increases electrical loading, so the memory controller typically hits its maximum supported rank-per-channel limit before bandwidth or thermal limits become an issue.
