128 GB DDR5 ECC RDIMM for ThinkMate servers

This 128 GB DDR5 4800 registered DIMM is built for ThinkMate HDX-XH24-52S4 high-density servers. It delivers ECC error correction and registered buffering for mission-critical workloads. The single-module design occupies one 288-pin slot while providing maximum capacity per channel. IT teams can scale memory without mixing kits.

Thermals noise and power at 1.1 V

Operating at 1.10 V, the module runs at standard DDR5 voltage for reduced power draw compared to earlier generations. No heat spreader is fitted, so airflow across the PCB manages thermals in dense chassis. Registered buffering and ECC logic add minimal latency at CL40 while maintaining signal integrity under sustained load. Acoustic profile depends entirely on system fan curves.

Fits ThinkMate high-density platforms

The 4Rx4 organisation suits motherboards qualified for quad-rank registered DIMMs at DDR5 4800. Compatibility is validated for ThinkMate HDX-XH24-52S4 servers; other platforms require vendor qualification. One 288-pin slot is consumed per 128 GB, freeing remaining slots for further expansion. Major OEM Samsung Micron Hynix chips ensure consistent supply and firmware alignment.

Questions about this item

How do I install this 288-pin DDR5 RDIMM in my Thinkmate server and which step is most often missed?

Power down the server, open the chassis, align the module key with the slot notch, press firmly until both retention clips lock, then verify in BIOS that the 128GB module appears at 4800MHz with ECC active.

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

No scheduled maintenance is required; the module either passes continuous ECC scrubbing or it fails, at which point the single 128GB stick is replaced as a unit under lifetime replacement terms.

What is the first limit that appears when this 4Rx4 module runs sustained workloads?

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