Server-grade capacity

This NEMIX RAM kit delivers 128 GB of DDR4 3200 memory across eight 16 GB registered DIMMs. It is built for ThinkMate TWX-XS8 tower servers that require ECC RDIMM modules to maintain data integrity under continuous workloads.

Registered DIMM integration

Each module presents a 2Rx8 organisation and operates at 1.2 V without a heat spreader, fitting directly into the 288-pin DDR4 slots of the compatible ThinkMate platforms. The registered buffer reduces electrical load on the memory controller, freeing the CPU to address the full 128 GB kit.

Sustained-load behaviour

Modules are stress tested under load before shipping, and the CL22 latency at PC4-25600 timing supports steady throughput during extended compute tasks. ECC correction operates continuously, preventing silent data corruption during long-running server applications.

Questions about this item

What is the CAS latency of these DDR4 3200 modules under sustained load?

The modules run at CL22, which is the rated latency at 3200 MT/s.

How much heat do the eight 16 GB RDIMMs generate when the server runs all day?

These sticks have no heat spreader and operate at the standard 1.20 V, so thermal output matches typical registered DDR4 at that voltage.

Which ThinkMate tower models must the buyer already own for this kit to work?

The kit is validated for TWX-XS8-14S3, TWX-XS8-24S3 and TWX-XS8-24S 3.1 tower servers.
