System-Specific DDR5 Kit

This 256GB memory kit contains four 64GB DDR5 RDIMM modules built for the Thinkmate GPX-XS8-24S4-4GPU workstation. It targets IT professionals and system integrators who need validated, registered ECC memory for mission-critical server and workstation deployments.

Registered ECC with 2Rx4 Organisation

Each module operates at DDR5 4800 (PC5-38400) with CL40 latency at 1.10V. The registered 2Rx4 architecture provides the signal integrity and error correction required by the qualified platform, ensuring stable operation under sustained enterprise workloads.

256GB Total Capacity Across Four Slots

The kit populates four DIMM slots with 64GB per module, delivering substantial headroom for virtualisation, large datasets and multi-application workloads. Capacity limits are defined by the workstation's memory-controller and slot count; configurations exceeding four modules or higher per-module densities are not supported by this kit.
