ThinkMate RAX-QE12 DDR5 ECC RDIMM Kit

This NEMIX RAM kit provides 128GB of DDR5 registered ECC memory in a matched pair of 64GB modules. It is built for the ThinkMate RAX-QE12 rackmount server and similar enterprise platforms that require registered DIMMs. The kit targets IT professionals upgrading mission-critical workloads.

Registered ECC DDR5 4800 CL40 2Rx4

The single specification that decides fit is the registered ECC RDIMM design running at DDR5 4800 with CL40 latency and a 2Rx4 organisation. Consumer motherboards and workstations that accept only unbuffered non-ECC modules cannot use this memory. Verify the server manual lists DDR5 RDIMM support before ordering.

Tool-free DIMM installation with seating checks

Installation follows the standard server procedure: power down, open the chassis, align the 288-pin key notch, and press firmly until both ejector tabs click. The most common issue is a module that appears seated but has one tab partially engaged, which causes a boot-time memory error. Reseat both modules and confirm tab lock before closing the case.

Questions about this item

What does the 4800 MT/s speed mean once the modules are installed in the ThinkMate RAX-QE12?

The memory will run at DDR5 4800 (PC5 38400) with CL40 latency at 1.1 V, delivering the rated bandwidth and timings the server platform supports.

How does the 288-pin DDR5 RDIMM interface affect what the kit can do in this server?

The registered 288-pin DDR5 RDIMM interface provides error-correcting code and registered buffering required by the RAX-QE12 motherboard, capping operation to the DDR5 4800 standard.

What physical space and slot layout does the 2 x 64 GB kit need to fit the RAX-QE12?

Two 288-pin DDR5 RDIMM slots are required; each module is a standard-height registered DIMM with no heat spreader, so they install directly into the server memory sockets.
