2TB DDR5 ECC RDIMM kit

This NEMIX RAM kit delivers 2TB of registered ECC DDR5 memory across sixteen 128GB modules. It is built for ThinkMate TWX-QS8 tower servers that require 288-pin DDR5 RDIMMs with error correction. The 4Rx4 organisation and CL40 latency suit workloads that prioritise data integrity over low-latency gaming or desktop use.

Sustained server workload behaviour

Registered buffering and on-die ECC keep signal integrity stable during continuous multi-threaded processing, virtualization or large in-memory databases. The 1.10V operating voltage helps limit thermal output when all sixteen slots are populated and the memory controller runs at the rated 4800 MT/s for extended periods.

DDR5 RDIMM platform constraints

The kit fits only systems that accept 288-pin DDR5 registered DIMMs with 4Rx4 ranking and CL40 timing at the JEDEC 4800 MT/s data rate. Workstations or consumer motherboards that require unbuffered UDIMMs, lower ranks or different latencies will not post with these modules.

Questions about this item

How much power does the 1.1 V DDR5 4800 kit draw when the ThinkMate server runs continuously?

Each module operates at 1.1 V, the standard DDR5 voltage; total system power depends on the server's memory controller and workload, not on the kit alone.

What must the ThinkMate TWX-QS8-14E4 or TWX-QS8-24E4 already have to accept this 16 x 128 GB registered ECC kit?

The tower server needs enough free 288-pin DDR5 RDIMM slots and a BIOS that supports 4Rx4 registered ECC modules at 4800 MT/s.

Can I mix these CL40 4Rx4 registered ECC DIMMs with older DDR5 modules already installed in the same ThinkMate server?

Mixing ranks, latencies or vendors is not recommended; the server will run all channels at the slowest common speed and may disable ECC or registration features.
