768 GB DDR5 4800 ECC RDIMM kit

This NEMIX RAM kit provides 768 GB of DDR5 4800 memory in six 128 GB registered DIMMs. It is built for the ThinkMate STX-NL-QE16 E4 nearline storage server and uses ECC RDIMM modules for data integrity. The modules operate at 1.1 V with CL40 latency.

Server administrators needing maximum registered

The six 4Rx4 modules fill all slots in the target platform, so administrators who need more than 768 GB or who require unbuffered UDIMMs cannot use this kit. It is also unsuitable for workstations or desktops that do not support registered DDR5 memory.

6 x 128 GB 4Rx4 registered configuration

The kit delivers its full 768 GB capacity only when all six 128 GB 4Rx4 RDIMMs are installed together in the compatible ThinkMate system. Mixing with other capacities or ranks will prevent the server from recognising the full memory amount.

Questions about this item

Will the 128 GB DDR5 modules need individual replacement if one fails?

The kit contains six 128 GB DDR5 RDIMMs; a single faulty module can be replaced without swapping the full 768 GB set.

What limits sustained throughput first on this registered ECC memory?

The DDR5 4800 MT/s data rate and CL40 latency set the bandwidth ceiling before thermal or power limits appear.

How much heat and power do the 1.1 V DDR5 RDIMMs produce under continuous load?

Each module runs at 1.10 V with no heat spreader, so airflow across the 288-pin DDR5 RDIMMs manages thermals during all-day operation.
