Purpose-built server memory kit

This NEMIX RAM kit delivers 1.5 TB of DDR5 capacity across twelve 128 GB registered DIMMs. It is designed for THINKMATE SuperServer 421GE-TNRT and 421GE-TNRT3 systems that require ECC protection and registered signalling. The modules run at 4800 MT/s with CL40 latency at 1.1 V.

Verify platform compatibility

Confirm that your motherboard supports 4Rx4 registered DDR5 DIMMs and can address the full 1.5 TB across all twelve slots. Check the system documentation for approved memory population rules and maximum per-slot capacity. Ensure the BIOS is updated to a version that validates this speed and rank configuration.

Registered ECC DDR5 for dense configurations

Each 288-pin module operates without a heat spreader, relying on chassis airflow for cooling. The registered design reduces electrical load on the memory controller, allowing all twelve slots to be populated. ECC circuitry corrects single-bit errors to maintain data integrity under sustained workloads.

Questions about this item

Does the 1.5TB kit include all 12 modules or must I buy extra DIMMs?

The kit ships with twelve 128GB DDR5 4800 CL40 ECC RDIMM modules, giving the full 1.5TB capacity in one package.

Why choose the 1.5TB 12x128GB CL40 kit instead of a smaller capacity?

This configuration fills all twelve slots with 4Rx4 registered DIMMs at 1.1V, delivering maximum supported density for the ThinkMate SuperServer 421GE-TNRT and 421GE-TNRT3.

What does the PC5-38400 rating mean for actual throughput in the SuperServer?

PC5-38400 indicates a 4800 MT/s data rate; the modules run at CL40 latency and 1.1V, providing the rated bandwidth when installed in the compatible ThinkMate platforms.
