192GB DDR5 4800 ECC RDIMM kit

This NEMIX RAM kit provides 192GB of DDR5 4800 memory across six 32GB registered DIMMs. It is built for the ThinkMate GPX-QH12-12E4-2GPU GPU-optimised server. The modules carry ECC and registered buffering for data integrity in mission-critical workloads.

288-pin registered modules without heat spreaders

Each stick uses a standard 288-pin DDR5 RDIMM form factor and runs at 1.1V. The 2Rx8 organisation fits the server’s memory architecture. Because there are no heat spreaders, the modules sit low in the chassis and leave clearance for tall CPU coolers or dense GPU arrangements.

CL40 latency at 1.1V for stable throughput

Rated at CL40, the memory delivers predictable latency for sustained compute tasks. The 1.1V operating voltage keeps power draw modest across all six modules. Registered buffering reduces electrical load on the memory controller, helping maintain signal integrity under continuous load.

Questions about this item

Does DDR5 4800 cap at PC5-38400 bandwidth?

Yes, the kit runs at DDR5 4800 which is rated PC5-38400, so that is the maximum standard throughput.

Will six 288-pin RDIMMs fit the ThinkMate GPX-QH12-12E4-2GPU memory slots?

The server takes 288-pin DDR5 RDIMMs and this kit provides exactly six 32 GB modules to fill the available slots.

What is the correct order to install the 2Rx8 registered modules?

Populate the channels in the sequence shown in the server manual — usually one module per channel first — so the memory controller trains all ranks before adding the second rank per channel.
