192 GB DDR5 ECC RDIMM kit

This 192 GB kit supplies two 96 GB registered DIMMs built for the Thinkmate RAX-XS4-21S4 rackmount server. Each module runs at DDR5 4800 with CL40 latency and on-die ECC for data integrity. The 2Rx8 organisation suits multi-channel server boards that require registered memory.

Thermals and power at 1.1 V

Operating at 1.10 V keeps power draw low for high-density server configurations. No heat spreader is fitted, so airflow across the bare PCB must be provided by the chassis fans. Registered buffering adds negligible latency while reducing electrical load on the memory controller.

Packaged as a matched pair

The kit contains exactly two 96 GB modules tested together for compatibility. No software, cables or additional brackets are included. Installation follows the server manufacturer's documented memory population rules.

Questions about this item

How do I install the 288-pin DDR5 RDIMM modules in the Thinkmate RAX-XS4-21S4 server, and what step is often missed?

Power off the server, open the chassis, align each 288-pin module with the DDR5 DIMM slots, press firmly until the retention clips lock, then verify in BIOS that all 192 GB are detected at 4800 MT/s.

What maintenance or replacement will the 2Rx8 ECC RDIMM kit need over its service life?

The modules have no heat spreaders and no moving parts, so no routine maintenance is required; if a module fails the lifetime replacement warranty covers a direct swap of the defective 96 GB stick.

At what point does the CL40 1.1 V DDR5 kit hit its sustained-use limit?

The registered 2Rx8 design and ECC correction keep error rates within spec at the rated 4800 MT/s continuously; the first limit encountered is the platform’s maximum supported memory capacity or DIMM slot count.
