ThinkMate DDR5 ECC RDIMM kit

This 768GB kit contains six 128GB DDR5 4800 registered DIMMs built for ThinkMate TWX-QS8-14E4 and TWX-QS8-24E4 tower servers. It targets administrators who need maximum memory capacity for virtualisation, databases or high-performance computing workloads.

Registered DDR5 for multi-socket servers

Each module is a 288-pin 4Rx4 ECC RDIMM running at 1.1V with CL40 latency. Registered buffering reduces electrical load on the memory controller, allowing all six modules to operate together in supported ThinkMate platforms without additional configuration.

Replaces lower-capacity DDR5 RDIMM sets

The jump is worthwhile when moving from smaller registered kits that leave DIMM slots empty or limit total system memory. It is not suited for workstations or desktops that require unbuffered UDIMM modules or non-ECC memory.

Questions about this item

Will the 1.1V operating voltage stay stable under sustained server workloads?

The modules run at 1.1V DDR5 standard voltage; registered buffering and ECC help maintain signal integrity during continuous operation.

How much heat do six 128GB RDIMMs produce when the ThinkMate tower runs 24/7?

No heat spreader is fitted; the 4Rx4 organisation and 1.1V rating keep per-module power low, so standard server airflow is sufficient.

Which ThinkMate models must I already own for this 768GB kit to work?

The kit is validated for ThinkMate TWX-QS8-14E4 and TWX-QS8-24E4 tower servers with DDR5 RDIMM slots.
