Capacity & compatibility

This 768 GB kit provides twelve 64 GB DDR4 3200 registered DIMMs validated for ThinkMate GPX-XS12-24S3-8GPU servers. It targets administrators scaling memory in GPU-dense systems that require ECC RDIMM modules.

Build integration

The 288-pin registered design plugs directly into the server's DDR4 slots and operates at 1.20 V. ECC and 4Rx4 organisation free the platform from single-bit errors while delivering high density without extra risers or adapters.

Thermals & power

Modules run without heat spreaders at standard 1.2 V DDR4 voltage, relying on the chassis airflow typical of ThinkMate GPU-optimised servers. Registered buffering and ECC add minimal overhead, keeping power draw predictable under sustained workloads.

Questions about this item

Does the CL22 latency remain stable when all twelve 64 GB modules run at 3200 MT/s continuously?

The kit is rated CL22 at 3200 MT/s across all twelve 64 GB modules, so the latency spec holds under sustained operation.

What thermal output or fan noise should I expect from this registered ECC kit during 24/7 server workloads?

The modules run at 1.20 V without heat spreaders, relying on chassis airflow; registered ECC RDIMMs add minimal thermal load compared with unbuffered DIMMs.

Which motherboard slots and chipset features are required to support this 4Rx4 288-pin DDR4 RDIMM configuration?

A ThinkMate GPX-XS12-24S3-8GPU platform with DDR4 RDIMM slots that accept 4Rx4 registered ECC modules is needed for full 768 GB capacity.
