Server-grade capacity kit

This NEMIX RAM kit delivers 768GB of DDR5 memory across six 128GB registered DIMMs. It is built for Thinkmate TWX-XS8 tower servers that require high-density ECC modules for virtualisation, database or compute workloads.

Suited for Thinkmate towers needing maximum DIMM

Administrators expanding a TWX-XS8-24S4 or TWX-XS8-14S4 to its full memory potential will use this kit. Systems that only accept unbuffered UDIMMs or run at lower DDR5 speeds cannot use these registered 4Rx4 modules.

Straightforward DIMM installation

Modules install in minutes by seating each 288-pin RDIMM into the server's slots following the manufacturer's population guide. The most common issue is ignoring the required slot order for 4Rx4 registered DIMMs, which prevents the system from posting.

Questions about this item

Does my Thinkmate TWX-XS8-24S4 or TWX-XS8-14S4 server need a specific BIOS version or CPU to run this 768GB DDR5 4800 kit?

The kit is validated for the Thinkmate TWX-XS8-24S4 and TWX-XS8-14S4 tower servers. Consult the server manual for any required BIOS updates before installing the six 128GB modules.

Can I mix these 128GB 4Rx4 registered ECC modules with smaller DDR5 RDIMMs already installed in my Thinkmate server?

Mixing different capacities or ranks is not recommended. For stable operation, populate all channels with identical 128GB 4Rx4 modules so the memory controller trains at DDR5 4800 with CL40 timings.

How do I verify the full 768GB is recognised and ECC is active after installing the six modules?

Enter the server BIOS or UEFI and confirm 768GB total capacity at 4800 MT/s. Check the ECC status field — it should show enabled or active for each of the six 288-pin RDIMMs.
