ThinkMate GPX-PS4 Server Memory Kit

This 512GB kit delivers sixteen 32GB DDR4 3200 ECC RDIMM modules built for ThinkMate GPX-PS4-12A1-2GPU and GPX-PS4-12A1-4GPU GPU-optimised servers. It targets administrators scaling memory capacity in these specific platforms. The registered design and ECC support suit mission-critical workloads that require data integrity. Buyers needing memory for non-ThinkMate systems or consumer motherboards should look elsewhere.

DDR4 3200 ECC Registered 2Rx8 CL22

The decisive specification is the DDR4 3200 (PC4-25600) ECC RDIMM profile with 2Rx8 organisation and CL22 latency at 1.20V. These parameters must match the server's qualified-vendor list exactly; a different rank, voltage or latency will prevent the system from posting. No other speed grade or unbuffered alternative is compatible with the target platforms.

Sixteen-Module Kit With No Heat Spreaders

The package supplies sixteen individual 32GB modules, enabling full population of the supported server's memory slots in a single purchase. Modules ship without heat spreaders, relying on the chassis airflow design of the GPX-PS4 series for cooling. There is no bundled software, firmware tool or installation hardware beyond the memory itself.
