128GB DDR4 2666 ECC LRDIMM Server Module

This 128GB DDR4 2666 ECC LRDIMM module is built for server platforms that require high-density registered memory with error correction. It suits administrators upgrading compatible Dell systems or similar enterprise hosts that support load-reduced DIMMs. Buyers needing non-ECC consumer memory or standard RDIMM form factors cannot use this product.

Thermals noise and power at 1.2V standard voltage

Operating at the DDR4 standard 1.20V, the module runs within normal server thermal envelopes without additional cooling requirements. Load-reduced buffering reduces electrical load on the memory bus, helping maintain stable power draw under sustained workloads. No heat spreader is fitted, so airflow across the DIMM slots handles dissipation.

288-pin DIMM slot fit and single-module capacity

The 288-pin DDR4 DIMM installs directly into a compatible server slot, delivering 128GB in a single module to free remaining slots for further expansion. ECC LRDIMM architecture requires a platform that supports load-reduced registered memory and 8Rx4 3DS/TSV organisation. Systems limited to standard RDIMM or lower densities will not accept this module.

Questions sur cet article

How do I install the 288-pin DDR4 LRDIMM and what step is often missed?

Align the notch on the 288-pin DDR4 LRDIMM with the slot key, press firmly until both retention clips click, then verify the server BIOS recognises the full 128GB at 2666 MHz.

What maintenance or replacement will the 128GB ECC LRDIMM need over time?

The module has no heat spreader and no moving parts; keep server airflow clean and run periodic memory diagnostics — replace only if ECC correctable errors rise or a diagnostic flags a hard fault.

What limit appears first on the 1.2V LRDIMM under sustained heavy workloads?

The CL15 latency at 2666 MHz and the 8-rank 3DS/TSV density set the throughput ceiling; the memory controller will hit bandwidth saturation before the 1.2V power envelope becomes a constraint.
