128GB DDR4 ECC RDIMM for ThinkMate servers

This 128GB registered DIMM is built for ThinkMate HDX-XN24-52S3, HDX-XN24-32S3, HDX-XN12-52S3 and HDX-XN12-32S3 platforms that require DDR4 3200 ECC memory. The single 1x128GB module uses a 4Rx4 organisation and CL22 timing to deliver high-density capacity in one slot. IT administrators handling virtualisation, database or compute workloads on these qualified systems can install it without mixing ranks.

1.2V operation keeps thermals and power low

Running at 1.20V, the module draws minimal power per gigabyte and generates little heat inside crowded server chassis. No heat spreader is fitted, so airflow from standard system fans passes directly over the DRAM packages. The registered buffer reduces electrical load on the memory controller, helping maintain signal integrity at 3200 MT/s without increasing acoustic output.

Major OEM chips validated under load

Each stick is assembled with Samsung, Micron or Hynix components and stress-tested under load before shipping to confirm stability in the listed ThinkMate models. The package contains only the memory module itself; no additional brackets, cables or software utilities are bundled. Compatibility is limited to the specified server families, so builders needing unbuffered UDIMMs or different form factors must select another product.

Questions about this item

How do I install this 288-pin DDR4 RDIMM in a ThinkMate server, and what step is often missed?

Power down the server, open the chassis, align the notch on the 288-pin module with the slot key, press firmly until both ejector clips lock, then verify in BIOS that the 128GB module registers at 3200 MT/s with ECC active; the step often missed is enabling ECC in the firmware after physical installation.

What maintenance or replacement will this 4Rx4 registered ECC module need over its service life?

No routine maintenance is required; the module has no heat spreader and runs at 1.20V, so keep server air filters clean for airflow. Replacement is only needed if a correctable error count exceeds the platform threshold or a hard failure occurs, at which point the lifetime replacement warranty applies.

What limit appears first when this CL22 3200 MT/s RDIMM runs under sustained load?

The CAS latency of 22 cycles at 3200 MT/s sets the baseline access latency; under sustained heavy workloads the memory controller’s thermal throttling or the 1.20V voltage floor typically becomes the limiting factor before the module’s own timing budget is exhausted.
