Compatible server memory kit

This NEMIX RAM kit supplies 64 GB of DDR4 3200 ECC registered memory in a matched pair of 32 GB modules. It is built for Thinkmate rackmount servers such as the RAX-XN24, XS4, XT10, XS8, XH8, XH10, XH12, XT24 and S3 platforms. The modules are tested for stability in enterprise workloads and carry a lifetime replacement guarantee. System administrators upgrading these specific Thinkmate models can install the kit with confidence.

Thermals and power

Each module operates at the standard DDR4 voltage of 1.20 V and runs without a heat spreader. Registered buffering reduces electrical load on the server memory controller, helping to keep power draw predictable under sustained use. The bare-DIMM design relies on the chassis airflow of the target rackmount systems for cooling. Noise and thermal behaviour will match the server manufacturer's original specifications.

Registered ECC requirement

This memory uses 288-pin DDR4 RDIMM modules with ECC and registered buffering, a combination required by the compatible Thinkmate servers. Systems that accept only unbuffered non-ECC UDIMMs cannot use this kit. Buyers must verify that their motherboard explicitly supports registered ECC DDR4 before purchasing.

Questions about this item

How do I install these 288-pin RDIMMs in a Thinkmate rackmount server and what step is often missed?

Power down the server, open the chassis, align each module's notch with the DDR4 slot key, press firmly until both retention clips click, then enter the BIOS to confirm the 64 GB kit is recognised at 3200 MT/s before loading the OS.

What maintenance or replacement will this 2Rx8 ECC registered kit need over its service life?

No routine maintenance is required; if a module ever fails the ECC logic will log correctable errors and the lifetime replacement warranty covers a direct swap of the defective 32 GB stick.

What limit appears first when this CL22 1.2 V memory runs sustained workloads in a Thinkmate XT24?

The CAS 22 latency at DDR4-3200 sets the timing floor, so sustained throughput is bounded by the 25600 MB/s peak transfer rate rather than thermal or voltage headroom.
