NEMIX RAM 256GB DDR4 3200 ECC RDIMM Kit

This 256GB kit contains two 128GB registered DIMMs built for ThinkMate RAX-XS4 and RAX-XH2 rackmount servers. ECC and registered buffering protect data integrity in mission-critical workloads. The modules run at 3200MHz with CL22 latency and operate at 1.20V. IT professionals needing validated compatibility for these specific platforms will find this kit fits directly.

Capacity and Headroom

Two 128GB 4Rx4 modules deliver 256GB total capacity for memory-intensive virtualization, database and analytics tasks. DDR4 3200 (PC4-25600) bandwidth supports high-throughput applications while registered signalling reduces electrical load on the memory controller. Workloads exceeding 256GB or requiring faster clock speeds will need a different configuration.

Thermals Noise and Power

The modules operate at 1.20V standard DDR4 voltage without heat spreaders, relying on server chassis airflow for cooling. Registered buffering and ECC logic add minimal power overhead compared to unbuffered alternatives. In normal server operation the kit runs silently with no moving parts and stays within typical DDR4 thermal limits when installed in supported ThinkMate systems.

Questions about this item

Will these 288‑pin DDR4 3200 RDIMMs work with the existing 1.2 V modules already in my ThinkMate server?

Yes — both kits run at 1.2 V and share the same DDR4 3200 PC4‑25600 speed, so they can operate together when the motherboard supports mixed capacities.

How can I confirm the 4Rx4 ECC registered modules are running at CL22 after installation?

Enter the BIOS or use a tool such as CPU‑Z; the memory tab will show DDR4‑3200, CL22 timings, ECC active and registered mode for each 128 GB DIMM.

Does the package include only the two 128 GB RDIMMs or are any cables or brackets supplied?

The box contains the two 128 GB DDR4 3200 ECC RDIMMs only; no cables, brackets or additional hardware are included.
