System-Specific DDR5 ECC RDIMM Kit

This NEMIX RAM kit provides 64 GB of DDR5 4800 memory in a matched set of four 16 GB registered DIMMs. It is built for Thinkmate Supermicro SuperServer platforms that require ECC RDIMM modules. The kit targets IT professionals upgrading compatible Thinkmate 111C-NR, 121C-TN2R or 121C-TN10R servers.

Registered ECC with 1Rx8 Organisation

The decisive specification is the registered ECC design combined with a single-rank 1Rx8 layout at CL40 latency. This combination determines whether the server's memory controller will initialise the modules correctly. Systems that expect unbuffered or dual-rank DIMMs will not accept this kit.

Straightforward DIMM Installation

Installation follows the standard 288-pin DDR5 DIMM procedure: power down, open the chassis, align the keyed notch, and press until the latches engage. The most common issue is populating slots in the wrong order for the specific SuperServer model; always consult the system manual for the approved population sequence. No heat spreader is fitted, so airflow across the bare PCB is required.

Questions about this item

What does the 4800 MT/s rating mean when the kit is installed in a Thinkmate Supermicro server?

The modules will run at up to 4800 MT/s on platforms that support DDR5 4800; the actual speed is set by the server's memory controller and may be lower depending on the CPU and DIMM population.

How does the DDR5 RDIMM interface affect usable bandwidth in these systems?

Registered DDR5 DIMMs add a clock cycle of buffering for signal integrity, allowing higher capacities per channel; the PC5-38400 rating shows the peak transfer rate the interface can deliver.

Will the 288-pin modules fit the memory slots in a Thinkmate 111C-NR or 121C-TN2R?

Yes — the kit uses standard 288-pin DDR5 RDIMM form factor, which matches the DIMM slots on the listed Thinkmate Supermicro SuperServer models.
