192GB DDR5 4800 ECC RDIMM Kit

This NEMIX RAM kit provides 192GB of DDR5 4800 memory in a matched pair of 96GB registered DIMMs. It is built for ThinkMate TWX-QS8 tower servers that require ECC error correction and registered signal buffering. The modules operate at 1.1V with CL40 latency and use a 2Rx8 organisation.

Upgrade from smaller RDIMM sets

Replacing lower-capacity registered DIMMs with this 2x96GB kit doubles or quadruples the memory available to each CPU socket. The jump is worthwhile when virtualisation hosts, database engines or large-scale analytics workloads exceed the current memory ceiling and the platform supports 96GB single-rank densities.

DDR5 4800 registered platform limits

DDR5 4800 registered DIMMs rely on the memory controller and BIOS to initialise ECC and on-die ECC features at the rated speed. If the server firmware does not recognise 96GB densities, the system may train at a lower data rate or fail to post. The 288-pin form factor fits only DDR5 RDIMM slots.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the memory slots in a THINKMATE TWX-QS8-14E4 or TWX-QS8-24E4 tower server?

Yes, the kit is built for those models and uses the standard 288-pin DDR5 RDIMM form factor that matches the server DIMM sockets.

What is the correct order for seating the two 96GB modules so the server recognises the full 192GB capacity?

Install the first module in the primary channel slot indicated in the server manual, then add the second module in the matching channel slot; both must be fully latched before power-on.

If a 2Rx8 registered ECC module fails its self-test years from now, what replacement does the lifetime warranty cover?

The lifetime replacement warranty provides a new 96GB DDR5 4800 CL40 2Rx8 1.1V ECC RDIMM of the same specification.
