128GB DDR5 ECC RDIMM kit

This 128GB kit contains four 32GB DDR5 4800 CL40 registered DIMMs built for Thinkmate TWX-QS8-14E4 and TWX-QS8-24E4 tower servers. Each module runs at 1.10V with 2Rx8 organisation and on-board ECC for data integrity in enterprise workloads.

Suited for Thinkmate tower upgrades

The modules are validated for the listed Thinkmate platforms and will not fit systems that require unbuffered UDIMMs or a different DDR generation. Buyers needing non-ECC memory or higher frequency bins should look elsewhere.

Sustained load behaviour

Registered buffering and ECC correction maintain signal quality during continuous server workloads. The 1.10V operating voltage keeps power draw steady across all four DIMMs under prolonged utilisation.

Questions about this item

Does this 128 GB kit need a ThinkMate TWX-QS8-14E4 or TWX-QS8-24E4 tower server to work?

The memory is validated for ThinkMate TWX-QS8-14E4 and TWX-QS8-24E4 tower servers that accept DDR5 4800 RDIMMs.

Can I mix these CL40 2Rx8 modules with older DDR5 ECC RDIMMs already in the server?

Mixing ranks or latencies may prevent the server from training at 4800 MT/s; populate all four slots with this matched kit for best stability.

How can I confirm the kit is running at 4800 MT/s with ECC active after installation?

Check the BIOS memory information screen — it should show 4800 MT/s, CL40, 1.10 V and ECC enabled for all 128 GB.
