16 GB DDR4 3200 ECC registered RDIMM kit (2 × 8 GB) validated for ThinkMate GPU-optimised servers
This 16 GB kit contains two 8 GB DDR4 3200 registered ECC RDIMMs built for ThinkMate GPX-PS4-12A1-2GPU and GPX-PS4-12A1-4GPU GPU-optimised servers. Modules run at 1.2 V with CL22 latency and a 1Rx8 organisation. The 288-pin form factor fits the qualified motherboard slots directly.
IT teams maintaining ThinkMate GPX-PS4-12A1 servers can install this matched pair to restore or expand ECC capacity. Builders working on consumer desktops, laptops or non-validated workstations should look elsewhere because the registered ECC design requires a compatible server chipset and BIOS support.
The single specification that determines compatibility is the registered ECC RDIMM module type; only systems qualified for DDR4 3200 registered ECC memory with 1Rx8 ranking will accept this kit.

Yes, the 288-pin DDR4 RDIMM design matches the registered DIMM slots used in the ThinkMate GPX-PS4-12A1-2GPU and GPX-PS4-12A1-4GPU GPU-optimised servers.
Power down the server, open the chassis, align each module notch with the slot key, press firmly until both retention clips click, then verify in BIOS that both 8 GB sticks are recognised at 3200 MT/s.
The modules are stress-tested and carry a lifetime replacement warranty; ECC error correction handles correctable errors in-service, so no scheduled chip replacement is required.
