Server-grade 128 GB DDR4 ECC LRDIMM

This module delivers 128 GB of DDR4 3200 memory in a single 288-pin load-reduced DIMM. It targets administrators upgrading compatible servers or workstations that require ECC error correction and quad-rank 3DS/TSV organisation. The 1.2 V operating voltage matches the DDR4 standard for this density. Desktop and laptop platforms cannot use this module.

Quad-rank 3DS stacking enables the 128 GB density

The 2S2Rx4 (4Rx4) configuration uses through-silicon via stacking to place four logical ranks behind a reduced electrical load on the memory bus. This allows the system to address 128 GB from one slot while maintaining signal integrity at 3200 MT/s. CL22 latency and 1.20 V operation are specified for the rated speed. No heat spreader is fitted on the module.

Installation follows standard server DIMM procedures

Align the notch on the 288-pin edge connector with the slot key, press evenly until the ejector tabs lock, then verify population order in the system manual for correct channel mapping. Common issues arise when the platform BIOS does not support quad-rank LRDIMM densities or when mixed-rank configurations violate the vendor’s memory population rules.

Questions sur cet article

Will the 288-pin DDR4 3200 ECC LRDIMM modules need replacement due to wear?

The 128 GB DDR4 3200 CL22 1.20 V ECC LRDIMM uses major-brand chips and has no moving parts; under normal server workloads it does not wear out and requires no scheduled replacement.

What limits sustained throughput on the 128 GB quad-rank 3DS LRDIMM?

The CL22 latency at 3200 MT/s and the quad-rank 3DS topology set the bandwidth ceiling during continuous heavy loads.

How much heat and power does the 1.2 V 128 GB load-reduced DIMM produce all day?

At 1.20 V standard DDR4 voltage the module draws nominal power and runs without a heat spreader, so thermal output stays within typical server DIMM limits.
