Capacity and compatibility

This NEMIX RAM kit delivers 1.5TB of DDR5 memory across 16 modules of 96GB each. It is built for the THINKMATE Supermicro SuperServer 121H-TNR, 221H-TNR and 221H-TN24R platforms. The 288-pin ECC RDIMM format with 2Rx4 organisation targets administrators who need maximum registered capacity in these qualified servers.

Thermals and power draw

Each module operates at 1.10V with a CAS latency of CL40 at 4800 MT/s. The registered buffer and ECC circuitry manage signal integrity under sustained load without a heat spreader. Power consumption scales with the 16-module population, so adequate chassis airflow is required to maintain stable temperatures during continuous operation.

Build integration

The kit occupies 16 DDR5 RDIMM slots and requires a motherboard qualified for 2Rx4 96GB modules at this density. It frees administrators from mixing smaller DIMMs to reach 1.5TB, simplifying population rules and leaving no empty slots for future expansion. Buyers whose platforms do not support 96GB registered modules or who need fewer than 16 slots should select a different capacity.

Questions about this item

How do I install the 16 DDR5 RDIMMs into the ThinkMate SuperServer 121H-TNR, and which slot-population rule is commonly missed?

Power down the server, open the chassis, and seat each 288-pin 2Rx4 module firmly until the ejectors click; the step most often missed is following the exact channel sequence shown in the ThinkMate service guide so all 16 slots are populated in the correct bank order.

What maintenance or replacement will the 1.5 TB DDR5 ECC RDIMM kit require over its service life?

The modules have no heat spreaders and no moving parts, so routine maintenance is limited to keeping server airflow paths clear of dust; replacement is only needed if a module fails ECC correction or the platform is upgraded beyond DDR5 4800.

At sustained load, which limit of the 96 GB 2Rx4 DDR5 4800 CL40 RDIMMs appears first?

The registered DDR5 4800 interface caps sustained throughput at the JEDEC PC5-38400 data rate, so memory bandwidth saturates before the 1.1 V power budget or the CL40 latency becomes the bottleneck.
