1TB Registered ECC DDR4 Kit

This kit provides 1 TB of registered ECC DDR4 memory across sixteen 64 GB modules. It is built for ThinkMate GPX-XT6-24S3-8NVLink GPU-optimised servers that require registered DIMMs with error correction.

Thermals and Power Draw

Each module operates at 1.20 V with a CL22 latency at DDR4-3200 speed. The registered buffer reduces electrical load on the memory controller while the modules run without heat spreaders, relying on server chassis airflow for cooling.

Build Integration

The 288-pin RDIMM form factor fits standard DDR4 server slots and the 4Rx4 organisation increases rank density per channel. Compatibility is validated for the specified ThinkMate platform; other systems must confirm registered ECC support and qualified-vendor-list approval before installation.

Questions about this item

How do I install the 16 registered DIMMs into the ThinkMate GPX-XT6-24S3-8NVLINK and what step is often missed?

Power down the server, open the chassis, align each 288-pin RDIMM with its slot and press firmly until both latches click; the step most people miss is verifying the memory population order in the ThinkMate manual so the 4Rx4 modules run in the correct channels.

What maintenance or replacement will this 1 TB DDR4 3200 ECC RDIMM kit need later?

The modules have no heat spreaders and no moving parts, so no routine maintenance is required; if a DIMM ever fails, the lifetime replacement warranty covers a direct swap of the faulty 64 GB stick.

What limit appears first when the 16×64 GB 4Rx4 kit runs sustained workloads at 3200 MT/s?

The quad-rank 4Rx4 organisation places the highest electrical load on the memory controller, so the platform’s maximum supported rank-per-channel limit is typically reached before thermal or bandwidth ceilings become an issue.
